光学レールRLAシリーズは、安定で剛性のあるメカニカルアセンブリの構築向けに、当社製品の中でも最小サイズの製品です。アルミニウムを機械加工しており、アリ溝付きの取付面には当社のスナップオン式レールキャリアが取り付け可能です。取り付けられた部品は、固定前にアリ溝式レール上を簡単にスライド移動できます。レール幅はわずか19.1 mmで、標準品は75~600 mmの長さでご用意しております。

こちらのアリ溝式光学レールにはM6ザグリ穴が多数付いており、部品を柔軟的に取り付け可能です。両端にはレールを垂直に取り付ける際のM4タップ穴が開いています。長さが300 mm以上のレールには取付用スロットも付いています。上部の写真でご覧いただけるように、レールには1.0 mm間隔の目盛りと、10.0 mm間隔の数値がレーザ刻印されており、オプトメカニクスハードウェアの精密な配置が可能です。

当社のRLAシリーズの光学レール製品には、スナップオン式レールキャリア取付アクセサリが含まれます。これらを、レールを水平や垂直方向に取り付けられるスペーサーセットやテーブルクランプと組合わせて用いることにより、あらゆるオプトメカニクスのセットアップに適した剛性のある汎用的な構築ブロックを作ることができます。

Hi, on the webpage diagram, the mounting hole is shown to be 4.4 mm from the bottom of the rail, but it appears to be 5.08 mm high in the CAD file for the RLA600/M. Could you confirm the value as it is important for our design? Thank you for your assistance.

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.

Hi, could you tell me the accuracy/bow/warp of a rail based on a certain length? Thank you.

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).

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.

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.

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.

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.

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 Luisa Nicoletti

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.

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. guy
jlow  (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.

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.

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, Jiabin

アリ溝式レールの断面図
  • コンパクトな構成のための当社最小サイズの光学レール
  • 両端にM4 x 0.7タップ穴付き
  • スナップオン式レールキャリアに対応
  • 光学素子の精密アライメント用にレーザ刻印された目盛付き

当社のアリ溝式光学レールは安定した1次元アセンブリの構築用に設計されています。 部品はアリ溝式取付け面のどの位置にも固定可能です。 レールの両端にはM4 x 0.7のタップ穴があるので、標準的なオプトメカニクス部品との組合せが可能です。

標準品は、75 mm~600 mmの長さでご用意しております。 1.0 mm間隔で目盛りが、10.0 mm間隔で数値が刻印されています。 レールは非常にコンパクトで、またテーブルクランプCL6を用いることにより簡単に光学テーブルやブレッドボードに固定できます。
