Current L200 Packaging
Smart Pack
- Reduce Weight of Packaging
- Increase Usage of Recyclable Materials
- Improve Packing Integrity
- Decrease Shipping Costs
Thorlabs' Smart Pack Initiative is aimed at minimizing waste while providing adequate protection for our products. By eliminating any unnecessary packaging, implementing design changes, and utilizing eco-friendly materials, this initiative seeks to reduce the environmental impact of our
product packaging.
The updated L200(/M) packaging consists of recycled cardboard and weighs 13% less than the original packaging. This weight change results in a
more than 6.71 kg reduction in travel-based CO2 emissions per year, based on typical product sales.*
The other products on this page have also transitioned to recycled paper packaging. The new L490(/M) packaging results in a 41% reduction in
weight and more than 107.46 kg reduction in travel-based CO2 emissions per year, while the updated LJ750(/M) packaging results in a 28%
reduction in weight and more than 5.15 kg reduction in CO2 emissions per year.*
As we move through our product line, we will indicate re-engineered, eco-friendly packaging with our Smart Pack logo, which can be seen in the
image to the right.
*This product transitioned to smart packaging in 2013. Travel-based emissions reduction calculations are estimated based on the total weight reduction of packaging materials used for all of that year's product sales, traveling 1,000 miles on an airplane, to provide general understanding of
the impact of packaging material reduction. Calculations were made using the EPA’s shipping emissions values for different modes of transport.

(posted 2023-04-10 11:13:36.007) Is it possible for the L490(/M) to be made with a knob on both sides, instead of just one side? cdolbashian
(posted 2023-04-13 10:24:00.0) Thank you for reaching out to us with this inquiry! We may be able to do this type of custom! I have reached out to you directly to discuss this. Dan Clark
(posted 2022-08-04 14:21:09.76) Would it be possible to have the lead screw swapped out to have a larger lead? I would like the full vertical travel to be accomplished in 10-20 turns, not 90, and I am hoping to stay away from a motorized stage. Would this alteration be possible? I would be looking to order two of these modified stages. cdolbashian
(posted 2022-08-05 04:44:32.0) Thank you for your interest in a variation of this product. Changing the number of turns would require a redesign in which the lead screw would be less TPI. Unfortunately for a single custom, this isn't feasible for us. That being said, I have requested this in our internal product development forum as the idea itself is sound. nandita menon

(posted 2022-01-19 08:15:40.0) Thank you for contacting Thorlabs. The approximate weight of our products is listed in the product's auto cad pdf drawing. The approx. weight of the L490 is 2.24 kg. Sergio Gonzalez
(posted 2021-05-28 11:20:36.42) I have a motorized labjack MLJ150/M. I am trying to control it via Kinesis software using USB cable but this seems impossible, always getting "Device not responding". Is there anything I could try ? jcater
(posted 2021-06-01 12:25:34.0) Response from Jack at Thorlabs: Thank you for your inquiry, I am sorry to hear this is happening. The 'device not responding' error can occur for a number of reasons. We will reach out to you directly to help troubleshoot further. user
(posted 2020-10-19 03:55:41.303) What is the accuracy and repeatability of height adjustment for LJ750/M? I know that graduation is each 10um, but is it possible to move ring eg. half of graduation? YLohia
(posted 2020-10-19 03:12:48.0) The pre-loaded design will allow for minimal backlash, making the repeatability and accuracy dependent on the user's dexterity to visually resolve the space between the engraved graduations. Typical users can indeed rotate the adjustment ring/knob by half graduations, so a 5 µm accuracy would likely be reasonable. Jason Yobby
(posted 2020-04-15 13:01:25.497) What is the fully open and fully closed heights of the L490? These dimensions are needed for bottom mounting hardware I am developing. YLohia
(posted 2020-04-15 02:39:48.0) Hello, thank you for contacting Thorlabs. The maximum and minimum heights for the L490 are given in the engineering drawing : https://www.thorlabs.com/_sd.cfm?fileName=1708-E0W.pdf&partNumber=L490. The top plate is 112.0 mm when fully extended and 54.7 mm when completely contracted. Decibel Elpa
(posted 2020-03-25 06:37:11.99) Where can I download the software for this motorized lab jack? I downloaded the software for the model that replaced this, but I am experiencing some problems. We had it installed previously but now we don't have the software for L490MZ/M. S/N 46844913 DJayasuriya

(posted 2019-12-17 06:44:48.927) The drawing for LJ750/M shows the top plate as having metric tapped holes with Imperial spacings - is that correct?
e.g M6 holes with 1 inch spacing. YLohia
(posted 2019-12-17 11:38:25.0) Thank you for contacting Thorlabs. Yes, the LJ750/M has metric holes that have imperial spacings. user
(posted 2019-11-14 10:28:36.273) Hello,
what is the maximum load if you use the L200 upside down ? That is, if the load pulls the two plates apart, instead of pushing them together. llamb
(posted 2019-11-18 02:04:59.0) Thank you for contacting Thorlabs. We have not formally tested the L200 for the inverted orientation, however, we would not expect failure of the unit when using the same load capacity. The key issues in this orientation would be repeatability and stability. When mounted upright on a table, the leadscrew and springs provide a mechanical advantage for a load compressing the two plates together. I have reached out to you directly to discuss your application and this lab jack further. user
(posted 2019-05-08 09:11:49.407) Hi!
You claim the Ø2.64" Compact Lab Jack(LJ750/M) has a "high stability" - what exactly do you mean with that? The load capacity or positional stability?
Do you have any numbers concerning the mechanical creep/long term positional stability of this stage?
I'm interested in moderate loads of about 5-10kg, over several hours/days. We are looking for a vertical stage that can keep it's position in the (sub)micron range. Other suggestions are welcome, too! llamb
(posted 2019-05-10 05:30:58.0) Thank you for your feedback. The high stability refers to being able to support a high load while maintaining its 10 µm resolution from the engraved dial. We have not tested the long-term positional stability of this stage, as it will also depend on thermal conditions and how the load is mounted. I have reached out to you directly to discuss your application further. xrb09126
(posted 2017-06-29 11:30:29.127) For the L200/M labjack we are having problems with what it seems to be the adjuster rod where iis struggling to move the jack at all? Just wondering if you can help tfrisch
(posted 2017-07-01 11:45:32.0) Hello, thank you for contacting Thorlabs. I will reach out to you directly to troubleshoot your labjack. dw
(posted 2017-03-22 16:59:11.467) After some use, these lab jacks tend to get jammed. It would be very helpful to have some info as to how to take apart the lab jack and fix this. jlow
(posted 2017-03-29 04:41:06.0) Response from Jeremy at Thorlabs: Typically the common cause for the stage getting jammed is dirt contamination on the lead screw. If you move the stage until it is at the end of the upright position, you can access the leadscrew somewhat to clean it with solvents (e.g. isopropyl alcohol). Once the lead screw is clean, you can then regrease it. The grease we use on the lead screw is Apiezon M. Afterwards, run the lead screw back and forth fully a few times. andrew
(posted 2013-07-23 06:32:01.503) We own a L490/M. Can we add the motorized stage to it?
L490MZ/M Motorized Lab Jack, 50.8 mm Travel, M6 Taps
http://www.thorlabs.hk/newgrouppage9.cfm?objectgroup_id=4018 cdaly
(posted 2013-07-25 10:34:00.0) Response from Chris at Thorlabs: Thank you for using our feedback tool. I'm afraid I am not sure if you are asking these can be mounted together or if the manual stage can be turned into a motorized one, so I will answer both. No, unfortunately, the L490(/M) cannot be motorized by adding the controller afterwards. Yes, you would be able to mount one on top of the other. In a perpendicular or offset configuration, you can just use M6 (1/4-20) cap screws, but if you are mounting them together flush to one another, you would need also to use the corresponding nuts in order to fasten them. rlang
(posted 2012-11-30 00:00:00.0) The L490/M includes 19 M6 mounting holes manufactured with 25 mm spacing. The tapped holes each include a positional tolerance that would allow the spacing to range between 24.87 mm to 25.13 mm. Our apologies, but our supporting documentation is currently inaccurate and will be updated shortly. Thank you for pointing out this inconsistency, and please note that the L490/M will suit your application. oleg.mavr
(posted 2012-11-28 11:17:17.123) This product would be very useful to our company if it is really "METRIC" as it is mentioned in short description of L490/M:
"The top and bottom plates each have an array of nineteen 1/4"-20 (M6) tapped mounting holes on 1" (25 mm) centers."
However one can see 25.4 mm spacing between tapped mounting holes. Please clarify is it possible to order L490/M with 25.0 mm spacing? tcohen
(posted 2012-05-14 09:34:00.0) Response from Tim at Thorlabs: Thank you for contacting us. The L490 uses anodized aluminum and stainless steel almost exclusively. There are, however, a few steel components which may not be stainless. I am checking into this and will contact you with more details. johannes.sparrer
(posted 2012-05-10 18:56:07.0) Is the L490 completely made of stainless materials? I would like to use it in an environment with a high humidity. eliseo
(posted 2010-06-01 00:04:15.0) Do you have any experience in making the L200 UHV compatible? Would it be feasible to scrub out the lithium grease and replace with vacuum grease? jjurado
(posted 2010-06-01 21:41:58.0) Response from Javier at Thorlabs to eliseo: we currently do not offer a vacuum-compatible version of the L200 labjack. There is not only grease, but other components that would require a redesign of the assembly in order to make the L200 vacuum compatibe (~10^-6 Torr). Alternatively, I would suggest looking at our LNR series stainless steel stages. We could customize its mounting accesories for use in vacuum environments. I will contact you with more details. apalmentieri
(posted 2010-01-27 10:00:00.0) A response from Adam at Thorlabs to rick: This is a very interesting application and we would like some more information. I will email you directly to get this information. With respect to the grease, the L490 uses Apiezon grease while the L200 uses white lithium for moving parts and a combination of Apiezon grease with NYE PG-44A grease. vvv
(posted 2010-01-26 16:47:55.0) I have an application for the L490 and or L200. The lab jacks would be used in a radioactive hot cell. That only causes problems if some kind of solid bearing material is used. Most lubricants are Ok, if one is used; I need to run it through our system.Your help will be appreciated.

(posted 2010-01-14 11:44:53.0) The STEP file thats available for L200 is flawed in a subtle but serious way. The hole spacings on the top and bottom plates are incorrect in one dimension. The holes, as modeled, are on a 1" x 25mm grid! tyler
