Linear Scales

Maximize performance of any optical encoder with precision glass scales by VC America. Rotary and Linear scales are manufactured using soda-lime glass with chrome reflective and absorptive layers optimized for 630-640nm (Red LED), with dimensional precision and low defect density.

Standard scales provide opportunity for fast evaluation and support production and we manufacture to customer specifications for unique patterns and dimensional requirements.
