Dovetail Optical Rails

The RLA Series of optical rails are our smallest rails. These compact dovetail rails are precsion machined on all surfaces to maintain good lateral alignment, which is necessary for an optical assembly. The rails are compatible with our RC Series snap-on rail carriers. Our snap-on rail carriers are easily inserted or removed from existing rail systems.
Both the rails and rail carriers are machined from an aircraft grade aluminum, which ensures good dimensional stability during manufacturing. The rails feature numerous 1/4" (M6) counterbores for mounting flexibility. Rails 12" (300 mm) and longer offer mounting slots to provide additional mounting flexibility. The end of each rail is 8-32 (M4) tapped for vertical mounting.
The rails are laser engraved with graduations every 1.0 mm and labelled every 10 mm. The scale allows for precise placement of rail carriers and attached hardware, crucial for instrument designs involving distance-sensitive elements such as lenses and non-collimated beams.
