Thank you for your assistance. cdolbashian
 (posted 2023-10-19 10:10:38.0) Thank you for for finding this discrepancy and notifying us. The correct measurement should be 5.08mm, measured from the bottom of the rail to the mounting hole. Matthias Müller
 (posted 2021-05-17 11:05:57.95) Hi,
could you tell me the accuracy/bow/warp of a rail based on a certain length?
Thank you. YLohia
 (posted 2021-05-20 11:35:35.0) Hello, thank you for contacting Thorlabs. While we don't spec the accuracy/bow/warp of these rails, we do spec their straightness (+/- 0.001"). This spec is valid for all the stock lengths that we offer (300 mm to 2400 mm). Drew Shields
 (posted 2020-10-18 01:56:34.857) Hi, I am wondering about using three of these rails to make a large (450mm square) x/y measuring grid. So I'd have two parallel rails for one axis, and a third rail, attached on each end to a rail carrier, sliding along those for the other axis. My question is if you anticipate this working well, sliding without resistance, and overall easy to use. Also wondering if others have tried this in the past. llamb
 (posted 2020-10-22 02:43:00.0) Thank you for contacting Thorlabs. Somewhat similar setups have been constructed in the past, so as long as both sliding rail carriers are given an even load to avoid more friction in one rail than the other, I do not see any major issues with your arrangement. c
 (posted 2015-02-11 10:21:47.5) Do you have any advice for mounting the rail straight onto an optical table? That is to match the axis of the rail with the line of holes of the optical table since there is a little play in the orientation as you screw the rail onto the table. cdaly
 (posted 2015-02-12 02:01:28.0) Response from Chris at Thorlabs: There's no specified way to ensure it is aligned, but what I have found is useful when using these is to put a screw through a mounting hole at either end and thread them down into the table somewhat, deep enough that the head of the screw is in the counterbore but loose enough that the rail is still able to move about with the small amount of play that exists. Then you can apply a small pressure to one side of the rail so that the rail is in contact with both screws. Tighten them down while doing this and this should help aligned the rail parallel to the grid of holes, or at least more so than just mounting it to the table without doing so. LNicoletti
 (posted 2014-04-14 18:29:36.723) Good morning,
I have a question on product RLA600/M. is it possible to attach two of them in order to make a 1200mm length?
thank you in advance

 (posted 2014-04-17 10:43:59.0) Response from Jeremy at Thorlabs: We do not currently have a rail joiner for this. There are tapped holes on both ends of this and there's not really a good way to ensure good alignment when two rails tighten against each other. You can bolt one piece to the table and then adjust the position of the 2nd one until a rail carrier slides somewhat smoothly between the two. We can also offer the rails in longer lengths but without features like slots, holes, and anodization. gyg2101
 (posted 2013-09-04 11:01:06.24) Hi,
I would like to automate a system based on your dovetail rails. Is there any way to "motorize" the rail carriers? I would need a couple of inches of computer-controlled motion.

 (posted 2013-09-10 15:32:00.0) Response from Jeremy at Thorlabs: Unfortunately we do not have an easy way to motorized the dovetail optical rail carrier at this moment. You could possibly put a motorized stage on top of the rail, but that better on the 66mm rail than the RLA dovetail rails. I will get in contact with you directly to discuss about your application. tcohen
 (posted 2012-02-22 17:15:00.0) Response from Tim at Thorlabs to Jiabin: Thank you for your interest in our dovetail optical rails. Unfortunately, we are currently unable to provide longer lengths than 600mm for this series. As an alternative, we are able to offer the XE25-CUSTRAIL/M up to 2000mm. We have contacted you with more information. jiabin.tuo
 (posted 2012-02-20 11:54:52.0) I would like to buy a Dovetail Optical Rail for my test, I am wondering can I custom the length to 2000mm?
Thank you for your time.
Regards,
