Frequently Asked Questions
They are used for optical applications that require low backscatter for the input or output surfaces of the disc.
They can be used in laboratory, industrial and OEM settings, laser optics, high-power laser systems, sensors, measurement systems, laser beam shaping, and spatial filtering.
The centering is PP or LQ and the aperture tolerances are 3-5 microns.
The diameter is 9.5mm +0.025 / -0.050mm (0.374in +0.000984 / -0.00197in) and the thickness ranges from 0.013 - 0.050mm (0.000512 - 0.00197in) to 0.254 - 0.381mm (0.01000 - 0.01500in).
The materials used are SS-302/304 per ASTM A666 with a blackened finish per SOP 037-BLACK, flat white finish per SOP 037-WHITE, tighter tolerances, glass (borosilicate), and PTFE Teflon.
