Precision Optical Filters Manufacturer
OPTOStokes Optical Filter Manufacturing & Engineering Support
OPTOStokes supplies stocked and custom optical filters, including bandpass, longpass, shortpass, ND, dichroic, fluorescence, Raman, notch and IR filters.
Precision Optical Filters for Research, Instrumentation and OEM Systems.
OPTOStokes Precision Optics Limited provides precision optical filters, custom-coated optics, and selected optical components for research, imaging, sensing, instrumentation, and OEM applications.
We support wavelengths from the UV through the LWIR, supplying both stock filters for fast evaluation and custom solutions for application-specific optical systems. Our filter portfolio includes bandpass, longpass, shortpass, neutral density, dichroic, fluorescence, Raman, notch, and infrared filters, together with optical windows, mirrors, lenses, and prisms.
For custom projects, our engineering support covers wavelength and substrate selection, coating design, precision cutting, spectral measurement, and performance review. Custom capabilities include narrowband and high-blocking filters, steep-edge designs, multiband filters, gradient filters, fluorescence imaging filters, Raman edge filters, and infrared filters.
Our focus is practical: helping engineers move efficiently from initial specification and prototype evaluation to stable, repeatable supply.
For custom filter requirements, contact sales@optofilters.com with your specifications and application details.
Optical Filter Manufacturing, Coating & Inspection
Our production workflow combines substrate preparation, thin-film coating, spectral verification, dimensional control, and final appearance inspection to support optical filter programs from prototype evaluation to stable volume supply.
