How to Specify

When requesting a quote for optical filters, providing the following information helps us give you an accurate quotation:

Filter Type
Bandpass, ND, longpass, etc.
Center Wavelength
Target wavelength
Bandwidth / OD
FWHM or optical density
Size
Dimensions or diameter
Substrate
Glass type preference
Quantity
Number of pieces

Engineering Considerations

When selecting bandpass filters, consider the angle of incidence — tilted filters shift the passband toward shorter wavelengths. For high-OD applications, stacking two filters can improve blocking performance. Absorptive ND filters handle high-power lasers better than reflective types. Always verify the damage threshold for your laser power density.
