Crystal Oven/Controller

Crystal Oven/Controller
Crystal Oven/Controller Crystal Oven/Controller

This oven and precision temperature controller is used to hold a crystal and maintain it at an elevated temperature. Such an elevated temperature is often required for noncritical phase matching (NCPM) or to avoid optical damage of crystals.

The crystal is first mounted in a Dia=10 mm metal cartridge before it is inserted into the oven to ensure an excellent temperature homogeneity.  For customer convenience crystals from Newlight Photonics can be pre-mounted in an oven upon request.
