Product Announcements: Pellicle Beamsplitters

National Photocolor Corporation is a manufacturer of off-the-shelf and custom pellicles. They offer a broad selection of pellicle beamsplitters, filters and windows for UV to IR applications... (read more)

Adding to our large inventory of coatings, National Photocolor 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. (read more)

Pellicles mounted to stands for use on optical-tables. Pellicle shown has an excellent transmitted wavefront quality and is used as a filter for Interferometers (read more)

Elliptical Pellicle Frames cut from tube at 45 Degrees.

This will minimize Vignetting of the Transmitted Beam. This enables transmission of a larger beam diameter (read more)

Pellicle Beamsplitters

Rolyn Pellicle Beamsplitters are precision optical components. The actual pellicle is an ultra-thin membrane. They are stocked uncoated and with 3 standard coatings: 50/50 dielectric @ 632.8

70/30 dielectric, 40/40 inconel. Special coatings also available (read more)

NPC Standard Pellicle Frames are stocked in 1",2",3",4",5" and 6" circular rings, plus 5"x7" rectangles. Top surfaces are beveled. The frame is black anodized, then lapped to create a flat at the inner edge.

The membrane is then stretched over the flat and firmly adhered to the beveled area. The machined aluminum rings have two threaded mounting holes on the back. (read more)

Pellicles manufactured by National Photocolor Corp. can be used for varied applications. Standard coatings cover wavelength ranges from the UV to IR. Many of the coatings are minimal loss type for power applications. (read more)

NPC Pellicles are fitted to post mounts and optical table mounts. Pellicle rings and mounts can be machined to specifications for custom applications (read more)

IR Pellicle Applications

Minimal loss (typical 45/55 R/T Ave.) beamsplitting pellicles are available for selected bandwidths within the 700nm to 5µ range. Coatings can be altered for different states of polarization as well as for single wavelength applications. (read more)
