Crystal Oven Controller

Although this circuit is small and simple the design use a pwm output to preserve the efficiency.

Crystal oven controller.

Some optical crystals e g. Thermocontroller tc2 can be managed from pc through usb or lan interface. Crystals crystal oven red optronics supplies a special designed crystal oven and temperature controller for heating and stabilizing crystals at a predefined temperature. The temperature of a quartz crystal for oscillator should to be kept constant to operate at very stable frequency.

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. The operating range is from room temperature up to 200 c which enables a wide wavelength tuning range. Here is the schematic diagram of the temperature control circuit. The involved time delays are often substantially longer than desirable in particular when the oven temperature has to be scanned through some range.

This oven temperature controller is suitable for such purpose. Alexandrite perform much better at an elevated and stable temperature.

Hc photonics hcp provides crystal ovens and controllers to well manage the temperature of nonlinear crystals especially ppln and pplt. Temperature controller tc2 together with co1 crystal oven is a high temperature set up to 200 c. Crystal oven controller this oven and precision temperature controller is used to hold a crystal and maintain it at an elevated temperature. Ordering instructions on bottom of page.

A crystal oven is a temperature controlled chamber used to maintain the quartz crystal in electronic crystal oscillators at a constant temperature in order to prevent changes in the frequency due to variations in ambient temperature. Click here for schematic installation and set up instructions. 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. An oscillator of this type is known as an oven controlled crystal oscillator ocxo where xo is an old abbreviation for crystal oscillator.

Crystal oven controller microwave l o. The ch 25 is an affordable alternative to professional channel element temperature compensation. 4 5 days heatpoint oven for nonlinear crystals.
