C-band is defined as 1525 nm – 1565 nm (but can be OEM customized)
100% dielectric materials – No polymers, epoxies, gelatins or metals
Grating chip thickness: 0.625 mm
Operating temperature at least 500° C
Packaging: Packed in semiconductor grade Gelpak containers, sealed in class 10 cleanroom

Product Overview

While we primarily supply PING gratings as OEM products, the following gratings, and many other gratings, are available from stock. You can order the gratings via the product links, or request a quotation on these or customized gratings.
