Crystal oven controller.

Such an elevated temperature is often required for noncritical phase matching ncpm or to avoid optical damage of crystals. An oscillator of this type is known as an oven controlled crystal oscillator ocxo where xo is an old abbreviation for crystal oscillator. Crystals crystal oven red optronics supplies a special designed crystal oven and temperature controller for heating and stabilizing crystals at a predefined temperature. The involved time delays are often substantially longer than desirable in particular when the oven temperature has to be scanned through some range.

Hc photonics hcp provides crystal ovens and controllers to well manage the temperature of nonlinear crystals especially ppln and pplt. Crystal oven controller this oven and precision temperature controller is used to hold a crystal and maintain it at an elevated temperature. The operating range is from room temperature up to 200 c which enables a wide wavelength tuning range. Alexandrite perform much better at an elevated and stable temperature.

Crystal oven is a device isolated box with the purpose of controlling the temperature of crystals for a stable phase matching protection from humidity or precise working temperatures. When the oven controller is turned on or when the desired crystal temperature is changed it will take some time until the oven has precisely reached the new temperature. Although this circuit is small and simple the design use a pwm output to preserve the efficiency.

Temperature controller tc2 together with co1 crystal oven is a high temperature set up to 200 c. The temperature of a quartz crystal for oscillator should to be kept constant to operate at very stable frequency. 4 5 days heatpoint oven for nonlinear crystals. Thermocontroller tc2 can be managed from pc through usb or lan interface.
