Optical Filters

Filmetrics optical filter

Filmetrics optical filters are used to flatten spectral response for improved measurement precision and to remove short-wavelength light that may damage light-sensitive films. These thin film optical filters are designed to work with many of our thin film measurement systems to reduce transmittance.
Measurement of optical filters themselves is usually an application best-suited for our F10-RT transmittance and reflectance measurement system.
