G29010e ` Precision Beam Splitter Optic – Coated Mirror in Machined Mount, Possibly Military Rangefinder
Detailed Description
We think this is a weird, precision-made optical part—possibly from a military rangefinder or laser alignment system. It features a clear rectangular optical glass (approx. 0.95" x 1.36") with a coated surface designed to pass or reflect a specific wavelength of light. The coating has a subtle hue, typical of dielectric or dichroic filters used in scientific and military-grade optics.
The optic is securely housed in a black anodized aluminum mount with multiple hex screw adjustments, likely for fine alignment. The build quality suggests it cost the government a small fortune when originally manufactured.
