|CPG3 - 30 mm Cage Plate Gasket|
This optical gasket is used to create a light-tight interface between two mating optical mounts. The highly compressible foam, measuring 0.25" (6 mm) thick in an uncompressed state, can easily adapt to uneven surfaces to maintain a light-tight seal between mating parts.
Most commonly used in cage assemblies, these gaskets are perfect for highly sensitive instrumentation such as CCD cameras and amplified photodiodes where ambient lighting is sufficient to saturate detection equipment or degrade signal-to-noise ratios.
