Smart Pack Goals

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 TS240 and TS240/M packaging consists of recycled cardboard and weighs 6.7% and 14.7% less, respectively, than the original packaging. This weight change results in a respective 0.86 kg and 1.85 kg reduction in travel-based CO₂ emissions per year, based on typical product sales. The other products on this page have transitioned, or are in the process of transitioning to recycled paper packaging.

As we move through our product line, we will indicate re-engineered, eco-friendly packaging with our Smart Pack logo, which can be seen here.

The design of this right angle mount limiting, and working with it is particularly frustrating. I cannot use it to securely connect 2 metric breadboards together at a right angle. The short side has 3 holes with 25mm spacing, hence I can connect it with >=2 screws to my breadboard. However, the long side has no holes spaced appart by a multiple of 25mm, which means that I can only have 1 screw connecting the long side of the right angle mount to my breadboard. This is extremely limiting ! It means that the breadboard can freely rotate around the single ancrage point. Is this a manufacturing issue, or is this by design ? If it is by design I think this is a design flaw which should be adressed. If you have a solution to this issue I would appreciate you getting back to me. Best regards, Theo Nass

Thank you for reaching out to us with this concern. Thankfully, on each side there are holes which are spaced at integers-of-25mm. I have contacted you directly to show you which mounting holes would be best to use with your application.

make metric to imperial adapter plates for hole spacing conversion. like a right angle bracket with 25 / 50 mm slot spacing on one side, and 1 inch slot spacing on the other arm. I want to mount a metric breadboard vertical on an imperial table. Also should make bread boards with interleaved metric / imperial and color code the holes with paint thanks

cdolbashian (posted 2024-10-30 04:19:59.0)

Thank you for reaching out to us with this feedback! For the smaller slotted right angle brackets, the slots are designed such that they could be used with imperial or metric spacing. For the larger brackets, as you mentioned, I think there is definitely some design space where a hybrid imperial-metric right angle bracket design could be advantageous. Regarding the imperial/metric breadboards, typically it is good practice to use all imperial, or all metric parts, to avoid stripping threaded holes and getting screws stuck or broken-off in threaded holes. I have reached out to you directly to discuss your suggestions.

I would like to get a copy of the Specification Sheet for the AB90B/M, if one exists, for my records and BOM. Thank you.

Thank you for contacting Thorlabs. We unfortunately do not have a spec sheet for this item. All the specifications and support documentation such as CAD drawings can be found on the product family page: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=223&pn=AB90B/M

Need vertical supports 300-500 mm tall. Your products do not have good structure when mounted on vertical rails

jpolaris (posted 2024-01-04 06:19:59.0)

Thank you for contacting Thorlabs. I have reached out to you directly to get clarification on the issue with structure of TS240 that you have found, as well as to work out a potential solution with you.

z lucky (posted 2023-01-31 18:37:15.27)

Why don't you just give simple dimension on the product like height and width. without having to go to all the other precedures.

jdelia (posted 2023-02-01 10:22:42.0)

Thank you for contacting Thorlabs. The length, width, and height of the AP90 bracket can be found readily available under the "Overview" section of our product family page.

David Moy (posted 2021-06-23 11:17:22.987)

We would like a version of this bracket where the 3 holes in the bottom (shortest) leg of the bracket are replaced with a single slot.

Hello, custom products can be requested by clicking on the "Request Quote" button above or by contacting your local Thorlabs Tech Support group. We will discuss the possibility of offering this directly.

There is an inconsistency. The title/label of this item says "M6 Tapped Holes" but the technical PDF drawing says "M6X1.0-6H THRU".

llamb (posted 2020-07-31 02:42:51.0)

Thank you for your feedback on the AB90A/M. The holes are indeed tapped with an M6 x 1.0 thread, as opposed to smooth Ø6 mm holes, and they pass THRU the entire material's thickness, as opposed to being blind holes of a finite depth. We will consider clarifying these call-outs.

gergely.ercsey (posted 2016-07-07 13:08:34.17)

Dear Madam/Sir! The holes should be in exact distance from the bottom. For example the first hole's axis distance from the bottom should be in 20mm. Best Regards, Gergely Ercsey

Response from Tim at Thorlabs: Thank you for sharing this idea with us! We would like to send you some complementary pieces for your feedback. We will also update this page to indicate that they were customer inspired.

I see you now have added the brackets I designed to the catalog! I will definitely be buying many of these!

Update from Tim at Thorlabs to the customer who couldn’t consistently fit the washer onto the XE25A90: Your suggestion led to an updated design that solved this problem. Thank you for your feedback!

Response from Javier at Thorlabs to Patrick. Thank you for your feedback. I will contact you directly to get details about your application. We can discuss the possibility of custom making this part and/or potentially adding it to our catalog.

patrick.berry (posted 2010-11-03 09:27:57.0)

It would be nice if you had some 90 degree brackets available which were the size of the AB90 but had 1/4-20 threaded holes on one or both sides. It would also be nice to have one that was half as wide, possibly with one counterbored 1/4-20 and one threaded on each side.

klee (posted 2009-09-14 17:15:44.0)

A response from Ken at Thorlabs to sabba_yoni: We do not have any angle bracket that is smaller than the AB90. However, we can custom make one if you can send us a sketch or drawing.

sabba_yoni (posted 2009-09-14 15:46:52.0)

i need a small "angle bracket" , like 1.5*1 inch did you have something like that?
