Oven for Nonlinear Crystals CH7

CH7 is a compact oven with build-in thermocontroller for temperature up to 60 °C. CH7 oven provides more crystal mounting options in comparison with CH3 or CH4. Like in CO1, each crystal is mounted into adapter before insertion in oven. CH7 and CO1 crystal adapters are compatible. Maximum crystal size for this model is 12x12 mm. and the length of the crystal - 30 mm.

The pre-set temperature can be adjusted in ±5°C range by the help of potentiometer. The current temperature is not indicated.  CH7 has “temperature ready” signal, changing state when pre-set temperature is reached. For additional protection of crystal surfaces from the dust or other contamination, we offer CH7-20 model – windowed version of CH7 oven.
