Opto Sigma

• Low profile and square aluminum rails
• Two standard widths
• Range of carriers offered
• Compatible with most mounting systems

When it is required to provide linear adjustment of the spacing of optical components over a wide range, the best way is to use a rail. The rails we offer have an extremely low profile so they do not cause excessive height build up. These rails are in the form of a dovetail. They are used with mating carriers which may be inserted at various points along the rail without interfering with adjacent carriers. Two widths of rail are offered, 50mm and 100mm. A series of slots along the centerline of the rail facilitates attachment to an optical table or breadboard. Both inch and metric hole spacings can be accommodated by the slots.

Alternatively the rails may be clamped using ledges along the sides. Each size of rail has its own series of carriers. These are attached by releasing the clamp screw and hooking the lip over the dovetail section on the rail. The clamp may then be loosely tightened to permit sliding or fully tightened to lock the carrier in place. On the upper surface of the carriers is a standard inch or metric mounting hole pattern which may be used to attach stages, post holders or other mounting devices. The surface is parallel to the base when in use.
