Reference cells contain vapors of specific atomic elements or molecular compounds, each of which has a well-defined absorption spectrum. These cells are commonly used in spectroscopic applications such as tunable diode laser calibration, stabilization of laser frequencies, and calibration of wavelength meters. Thorlabs offers both borosilicate and quartz reference cells that contain a range of standard fill materials. Custom reference cells can be manufactured upon request.

Since each fill material is associated with a unique absorption spectrum that serves as its fingerprint, the contents of a reference cell can be determined via a linear absorption measurement (as depicted by the simplified schematic above). By scanning a tunable diode laser over a wavelength range and detecting light absorption (A) with a photodetector, a series of peaks will be recorded, which is characteristic of the vapor inside the cell.

All of the cells offered here are baked and evacuated to 10-8 Torr prior to filling in order to remove contaminants. Additionally, each cell is helium leak checked to ensure the longevity of the vapor cell. The vapor pressure of the alkali metal will cause it to migrate throughout the cell and condense at the coolest area. Heating the windows of the cell rather than the cell body will help ensure the windows stay warmer and thus that the alkali will collect elsewhere. If obstruction of the optics becomes an issue, apply cooling to an area on the cell body, such as near the fill stem, and heat the windows in an alternating fashion to drive the metal from the window surfaces and collect it at the cool spot. The metal may eventually move back to the windows depending on how the cell is heated.

Please note: These reference cells are subject to hazardous goods regulations and must be shipped separately using specifically regulated shipping methods and may require special shipping and handling charges. Next day delivery is not available. All orders will ship from our US warehouse regardless of destination and cannot be returned. Due to hazardous materials shipping regulations, we are currently unable to ship our reference cells to Brazil, China, or Uruguay.

Mounting & Heating Options
These cells can be mounted in our V-Clamp Mounts, which are available in standard, kinematic, or Ø1.5" post-compatible versions. Please check that the cell diameter is supported by the mount. Our VBC1(/M) and VBC2(/M) Post-Mountable Band Clamps provide a distributed clamping force that is well-suited for holding glass cells without marring. The cells can be heated using the GCH25-75 Glass Cell Heater, illustrated in the Application Idea at the top of the page, or the GCH25R Heater Caps, shown in the photo above. Our HT10K and TLK-H Resistive Foil Heaters wrap around Ø25.4 mm glass cells and feature adhesive backing.

We also offer sealed acetylene reference cells for frequency and wavelength calibration. Also available are pre-assembled compact and Herriott multipass cells for gas absorption spectroscopy applications as well as empty glass cells, glass cells with angled windows , glass cells with Brewster windows, glass cells with textured windows, and threaded glass or stainless steel cells for custom spectroscopic applications.

Dear Thorlabs Team, I assume in specs sheet the mentioned pressure is for the pressure of Rb vapor. The pressure is 10^-7 Torr for borosilicate tube and >0.1 Torr for quartz tube and in MSDS sheet it is showing Density at 20 °C (68 °F): 1.532 g/cm³ for both the cell. Are the amount of Rb is different for both the cell?
jpolaris  (posted 2023-12-19 07:45:29.0)
Thank you for bringing to our attention the discrepancy in the pressure specifications between our borosilicate and quartz vapor reference cells. Both the borosilicate and quartz versions of these cells are evacuated and sealed closed while actively pumping in the 1E-8 range. As the stem is heated to collapse, the manometer reads in the low 1E-7 range. Once the cell is sealed, there is a natural vapor pressure inside the cell which increases with temperature. We do not have hard data on the vapor pressure inside the cells. However, we do know that there is 2 mg - 5 mg of alkali metal within both cells.

Dear Thorlabs team, do you have information related to the lifetime of the Rb vapor inside the cell? I really appreciate any help you can provide. Marino

Thank you for reaching out to us! We unfortunately do not have lifetime spec for these cells. We have had customers in the past report constant use for 6 weeks until the reference signal was no longer viewable, though they were a bit brief in the conditions in which they were testing. We recommend use at 80-125C as higher temps will cause the alkali metals in the reference cells to react with the glass tube at a faster rate, thus diminishing the lifetime of the reference signal.

Dear Sir/Madam, For a customized vapor cell, I would like to know the minimum ID of the Rb reference cell you can provide? Is it possible to fabricate a 500mm long vapor cell in parallel? How is the lifetime reduced with a thin SiO2 wall? Otherwise, one question for the pressure level of the reference cell, why it is 10^-7 Torr for borosilicate tube and >0.1 Torr for quartz tube? Thank you in advance and best regards, Ximeng ZHENG

Hello, I've been using two of your quartz reference cells for atomic magnetometer applications, 87Rb and Cs. I have read in one of the comments below that it is advised to operate them below 110ºC. Can you confirm me if this is the case for both cells I'm using? Nevertheless, I have been heating them up to 70~80ºC and I noticed that both Rb and Cs have deposited on the angled walls of each of the cells; does this mean that I have damaged the cells in some way or are they still functional?
YLohia  (posted 2020-10-15 11:04:27.0)
Hello, thank you for contacting Thorlabs. Although there have been no published papers to our knowledge on the topic of alkali reaction with glass in excess of 110C, we have plenty of anecdotal evidence the phenomenon does occur. The reaction is slow at 110C but the higher the temperature, the faster the reaction until all the metal is consumed. Due to the chemical composition, the reaction with Pyrex (borosilicate) is slower than with quartz (silicon dioxide). Operation at 70-80C should provide many years of trouble-free use. Each cell is He leak checked to ensure UHV compatibility prior to being added to a vacuum manifold. The cells are baked out and evacuated to 1E-8 Torr prior to the addition of alkali metal. Under 1E-7 Torr and lower, alkali metal has a natural vapor pressure and will migrate throughout the cell to find the coolest area to condense. Heating the windows of the cell rather than the cell body will help ensure the windows stay warmer and thus the alkali will collect elsewhere. If obstruction of the optics becomes too big of an issue, apply a cool spot to the cell body, perhaps at the fill stem, and heat the windows in an alternating fashion to drive the metal from the window surfaces and collect it at the cool spot. The metal may eventually move back to the windows depending on how you are heating the cell. The fact that you can see metal in the corners means the cells are perfectly fine.

Hello, Regarding the Rb87 cell, I'm undergoing a master's dissertation where I'm trying to study the influences of light and magnetic fields on the vapour cell. My project funded the cell you have currently commercially available. I've been using it for a while and I can attest that the manufacturing is remarkable and well done, I've had no issues with it whatsoever. I have a few questions I've been struggling to get cleared up and I'm wondering if you know the values of relative permitivity, relative permeability and electrical conducitivity of the vapor of Rb87 you have in your cell. Also, I've downloaded your CAD files in order to use the model to import in COMSOL and after trying to re-edit on Solidworks I can't seem to access all the functionalities of the software with the files you provided. I wanted to fill the interior of the cell with a solid, because in COMSOL, so that magnetic field equations become appliable I need a volume inside the cell, not a surface around, and I haven't managed to do so because it simply doesn't let me. I was wondering if you had a model like that or could quickly sort one out. I am extremely sorry for the long text and the plentiful of questions I have asked. If you don't have an answer for them it's alright, I'm just trying my best to gather the information I need to do a good project, as the literature doesn't cover certain aspects. Best regards.

I'm interested in the I2 cell, but concerned with the statement of, "Although quartz will survive temperatures up to 800 °C, the reference vapor will be consumed by reactions with the wall of the cell at temperatures significantly lower than quartz's melting temperature." I want to use the cell at near room temp. Is the suggestion that I would be losing I2 there? Additionally, it seems that the cell has a small pressure of the I2 vapor and some buffer gas. What is the pressure of the vapor and the pressure of the buffer gas? Lastly, can you send my a reference spectra at 18788 cm-1 nm?
nbayconich  (posted 2018-04-02 10:40:08.0)
Thank you for contacting Thorlabs. For the Iodine vapor reference cells there is no indication that the Iodine vapor will react with the quartz cell or glass at any temperature. Most reactions occur with alkali metal vapor reference cells at high temperatures around 110 degrees Celsius. The quartz cell alone can handle temperatures up to 800C however we recommend the operating temperature of the vapor inside the reference cells to be below 110 degrees Celsius for any reference cell using an alkali metal vapor such as Cesium or Sodium. These cells are sealed at a pressure of 1 x 10-8 Torr 25 °C and the buffer gas is helium. We do not have any reference spectra at the moment for these particular iodine vapor cells but I will reach out to you directly with some references.

Good to see these as being available again. However, do you charge "Hazardous cargo" shipping charges for these? To ship to Australia, other suppliers say they must specify hazardous cargo, which means they cannot go on passenger planes, and the additional cost is very high (approx. $500). If you can circumvent that it makes your cells significantly lower in cost. Thanks

Dear Kevin, The yellowish gold film that you see on the cell is most likely condensed Na. As you heat the cell, the vapor pressure increases, causing the vapor will coat the cell walls themselves. If you blow warm air onto the areas of the cell where this condensation has occured using a heat gun (or even a hairdryer) while keeping the rest of the cell cooler, youll be able to remove the condesed vapor from the surfaces that you need access to for your experiment.
Kevin.lyon  (posted 2007-11-21 11:50:22.0)
We have purchased this cell along with the heater GCH09-150 and the associated controller. The cell works fine however the heater was only rated for 80 C which does not provide hardly any vapor pressure for sodium. It may be enough if you are looking at absorption however for any fluorescence it is insufficient heat. We then used heater tape to heat the cell to around 150 degrees and got the results we needed however the cell turned an odd yellowish gold. I am not yet sure what reaction may be responsible for this however the cell still provides an atomic sodium spectra despite the discoloration.

Note that for the iodine reference cell GC19100-I, the length is 100.0 mm rather than 75.0 mm.

Thorlabs' quartz reference cells feature UV fused silica windows for superior transmission in the UV spectral range. The windows, which are angled to compensate for beam offset, are designed with a 2 degree wedge so as to eliminate etalon effects.

The rubidium reference cell (GC19075-RB) is sold with the natural isotope ratio of Rb, which is 72.15% 85Rb and 27.85% 87Rb . A version is also available with 98% pure 87Rb (GC19075-RB87).
