PPLN Oven Mount Adapters
For easy integration into your optical arrangement, Covesion provides a flexible range of oven mounting adapters for post mounting solutions or flexure stage solutions, as well as a small compact mount for oven-free arrangements.
Temperature Controller
For high stability temperature control, the Covesion OC2 is a compact stand-alone bench-top unit for use with our PPLN oven range.
PPLN Ovens
For fixed wavelength applications PPLN should be maintained at a constant operating temperature for maximum conversion efficiency. In tunable wavelength applications the temperature of the crystal can be adjusted for fine wavelength tuning.
