The current OPTOStokes product catalog spans bandpass filters, optical filters, shortpass filters, longpass filters, dichroic mirrors, neutral density filters, fluorescence filter sets, PCR optical filters, NIR bandpass filters, SWIR filters, IR filters, and precision optical flats and laser windows. The paginated listings also show concrete stocked or promoted examples such as ND90%, ND65%, LP500, LP580, LP920, LP940, LP960, BP810, BP905, BP940, and large-aperture laser flat windows. That matters for buyers because one catalog already covers attenuation, edge filtering, NIR signal isolation, fluorescence paths, and precision windowing without forcing you to source across multiple vendors.
