Heat; Air Quality And Humidity - THORLABS SPDC810N User Manual

Narrowband Photon Pair Source
2.3.2 Heat
The SPDC810N crystal temperature is regulated by a resistive heater oven. Make sure that there is sufficient
clearance around the device (approximately 1" on all sides) to allow airflow.
2.3.3 Air Quality and Humidity
The SPDC810N source is not hermetically sealed. Small amounts of contamination and moisture can penetrate
the enclosure. An excessively dusty or humid environment will damage the system.
The humidity should be controlled to avoid condensation and resultant damage to optical components. The
system should not be placed close to air handling vents (cooling or heating), to avoid sudden changes of humidity
and/or temperature.
