New! 500 Watt Thermopile Detector, Model 818P-500-55!
Newport’s 818P Series High Power Thermopile Detectors provide a full range of the highest quality detectors to meet most laser power measurement needs. These thermal detectors offer broadband, spectrally flat power detectors for general use. High peak power pulse damage resistance in specific UV and IR bands are also available. Maximum power range up to 500 Watts. Higher maximum power ratings require heatsink, fan, or water-cooled operation. Standard apertures of 12, 19, 25 and 55 mm are available. Volume absorber versions with an 18mm aperture are also available. Typical applications include measurements of CW or pulsed Ion, Nd:YAG, Ti:Sapphire, CO2, Holmium lasers, high-power laser diodes and Excimer laser measurements in the UV range.
Each 818P thermopile detector include a DB15 connector and internal EEPROM for storing factory calibration data, making them compatible with Newport's 1936-C and 2936-C (see Optical Power and Energy Meters, High Performance, 1936-C/2936-C ), 1928-C (see Benchtop Optical Meter, 1928-C)and 1918-C (see Optical Power Meters, High-Performance, 1931-C/2931-C) optical meters. When using with Newport's legacy 1835-C and 2835-C Series Optical Meters, use the adaptor cable 818P-DIN (ordered separately).
All 12mm aperture thermal sensor heads have a 8-32 tapped hole and all other detectors have a 1/4-20 tapped hole for post or plate mounting.
Calibration of the thermopile detectors is required annually to assure NIST traceability. Newport’s recalibration services are geared to provide fast turnaround to meet your tight schedule. |
