National Photocolor is a manufacturer of pellicles used as beamsplitters, filters or protective windows for the optics industry. We offer a broad selection of pellicle beamsplitters, filters and windows for UV to IR applications. Many custom type coatings and specially sized mounts are available for shipment within days after receipt of an order. In addition to special pellicle membranes, frames and coatings we offer technical and prototype design assistance.
As each application is different, we welcome your call, fax or email. We will help you design the right pellicle for your application. Critical reflection flatness specifications met, often with better than one wave flatness. For critical transmission applications: better than 1/10 wave and fractional fringe thickness uniformity.

The frames are black anodized aluminum which is lapped and polished for best reflection flatness.
National Photocolor has manufactured circular pellicles as small as 1/16"ID to greater than 15"ID.
NPC also manufactures rectangles, ellipses, truncated cylinders, and triangular frames.
We enjoy collaborating with customers to create the best design for a particular application.

National Photocolor offers seven (7) standard frames and we routinely mount pellicles on custom frames.
Frames, which should be designed in conjunction with NPC, may be supplied by the customer or National Photocolor.
Frequently, a frame can be quickly and inexpensively supplied from our large inventory of special frames.
Custom frame design is usually similar to standard design, although cross sections may be altered and the bevels varied or eliminated.
Though flatness of standard pellicles is suitable for most uses, some applications require unusual flatness.

Using improved manufacturing techniques NPC now provides Ultraflat Pellicles with up to 1/10 reflection on central areas of smaller diameter pellicles.
Better than 1 wave reflection flatness can be obtained on larger diameter pellicles.
The central 75% to 80% central area of a circular pellicle is normally specified as the best area for reflection flatness.
Computer reduced interferometric documentation can be provided.
Specially manufactured pellicles with transmitted wavefronts of better than 1/10 are available.

Specially manufactured pellicles with transmitted wavefronts of better than 1/10 are available.
Adding to our large inventory of coatings, NPC now carries minimal loss 45%/55% R/T Average coatings for wavelength ranges 400nm to 700nm, 700nm to 900nm, 1um to 2um and 3um to 5um.
We can select these coated pellicles for single wavelength and angle applications for P, S, or unpolarized light.
Transmission documentation is provided.
