Approximately: 40% at 193nm, 45% at 250nm, 55% at 0.4um, 65% at 0.6um, 70% at 0.8um, 80% for 1 -3um
Power Meters FAQ's
We only have data to 10.6um but have reason to believe that it absorbs >80% up to 40um.
It can be used and is calibrated but very poor accuracy ~15% and high reflectance ~85%
No. The diffuser transmits very little past 2.5um. Use the PE50-DIF-ER.
PE sensors are Pyro Electric and they require both a heating and cooling cycle to generate a voltage to produce the signal read by the display. With a CW laser the sensor is never able to go through the cooling cycle, so it does not generate the voltage needed to produce the signal read by the display. If you have a CW laser, it is better to use a Thermal or Photo Diode sensor depending on your laser’s wavelength. Please contact your local Ophir representative for assistance in selecting the correct sensor for your application.
