Thermoelectric Cooling NIR-PMT Module H12694A

The H12694 series are compact NIR-PMT (Near Infrared Photomultiplier Tube) NIR-PMT modules developed using advanced photocathode technology.The NIR-PMT is contained in an adiabatic hermetically sealed enclosure pumped to a high degree of vacuum. Its internal thermoelectric cooler does not require liquid nitrogen or cooling water.
The optical input window of these modules uses a concentrating lens to provide a virtually larger photosensitive area for easy optical coupling. A gate function prevents saturation caused by excessive light input. Adapters for connection to optical fibers and monochromators are also available as options.
