This datasheet tells the reader information such as sensitivity, radiant sensitivity, and amplifier. In this datasheet we can find description regarding characteristics, laser, and laser sensor.
Lots of information regarding maximum response wavelength, response, and uv laser sensor are explained inside this datasheet. The following are taken from the datasheet:
UV Laser Sensor Modules provide high sensitivity in the VUV to UV region. Excellent solar blind characteristics eliminate the need for visual cut-off filters, thus extending the service life of the module. The phototube is assembled in a compact, easyto-use TO-8 style package, along with a high voltage power supply that operates by low voltage input. The H8497 further incorporates an amplifier for voltage output. FEATURES GUV Laser Monitor Excimer laser YAG laser (4 ω: 266 nm, 5 ω: 213 nm)
Also, this datasheet gives the reader info around maximum response, and signal output.
