Precision Optical Rail, 36.48 in. Length, 3.93 in. Width, 36 in. Scale

The PRL Series Precision Dovetail Optical Rail system maintains a low profile with its 3.93 in. (99.8 mm) wide base to provide a sturdy hold of carriers with a combined height of 1.26 in. (31.9 mm). The precision-machined, anodized aluminum dovetail construction provides smooth and easy-to-use carrier translation with a straightness of 0.001 in over 8 in. (25 µm over 25 cm).

The optical rail carriers are also easy to use and may be removed or installed at any point on the rail. The aluminum carriers ride on extra-hard polymer pads, selected for low friction, resistance to cold flow, and long life. The overall nominal height of a carrier mounted on to an optical rail is 1.256 in. (31.9 mm). Convenient thumb-adjust lock knobs securely clamp the carriers in place anywhere on the rail.

A metric and imperial linear scale is engraved in the side of the precision-machined anodized aluminum optical rail for ease of optical system set-up.
