Chengdu Optical Coating
Laboratory, Inc manufactures high tolerance,
precision prisms in standard (right angle, porro,
trihedral, etc) or customer designs.
Capabilities include angle tolerances as small
as ¡À arc, surface quality
of 10-5, and sizes from under 1mm to as large as
120mm. AR coatings designed specifically for
your requirements can be applied to the entrance
and exit faces. Call us with your requirements
or send us your print for a quotation.
