Molded Composite Material

ValuMax® SPV Series Optical Mounting Posts are precision molded from a composite material known as Ryton® and have a 0.5 in. (12.7 mm) diameter. The composite material has an exceptional degree of thermal stability, dimensional stability, and chemical resistance.

Tapped Holes in Both Ends

These optical posts each have an 8-32 (or M4 for the metric equivalent) tapped hole in one end and a 1/4-20 (M6) tapped hole in the other. Each post is supplied with a 8-32 (M4) double-ended set screw, for joining posts together to create customizable lengths.

Available in Six Standard Lengths

SPV series optical posts are offered in six different heights between 0.75 in. (19.1 mm) and 4 in. (101.6 mm). The length of the optical posts, in inches, is included after the dash in the model numbers, with the following available: SPV-.75 , SPV-1 , SPV-1.5 , SPV-2, SPV-3 , and SPV-4. These are all also available in metric versions (which include an ""M-"" prefix in the model number).
