National Photocolor offers a wide variety of coated pellicles from their large inventory.

NPC Standard Uncoated Pellicles have an average R/T ratio of 8/92%, from 350nm to 2.5µm.

The following are Standard Coatings kept in their constantly updated inventory.

All R/T ratios may vary with wavelength and angle of incidence.

All illustrated curves are for unpolarized light at 45° angle of incidence. In general, a given coating will transmit more P polarized light than S polarized light; a coating will usually reflect more S polarized light than P polarized light. Coatings can be provided on a custom basis for your specific state of polarization.

Reflection/Transmission can be documented on request...
