Features

76 mm, Single-rail System with Stiff Box Beam Cross-section Construction

This unique New Focus 3.0 in. (76.2 mm) wide optical rail system uses an enhanced box-beam cross section to reduce weight to 10 oz./ft. (1.8 kg/m) without sacrificing stiffness. Rails are available with either 12.0 in (305 mm) or 24.0 in (610 mm) length.

English and Metric Linear Scales

Both Metric and English rulings are printed clearly on each optical rail. This helps to speed-up optical system set-ups.
