Newport’s 818P Series Thermopile Detectors provide a full range of detectors to meet the power measurement needs for CW or pulsed Ion, Nd:YAG, Ti:Sapphire, CO₂, Holmium lasers, high-power laser diodes and Excimer lasers. 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.

Each 818P thermopile detector include a DB15 connector and internal EEPROM for storing factory calibration data. 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 recommended annually to assure NIST traceability. Newport’s fast turnaround recalibration services will meet your tight schedule.

Note: For Gaussian beams multiply power and energy density by a factor of 2 when comparing to online damage threshold specifications. For beams with hot spots multiply power and energy density by a factor of 3 when comparing to online damage threshold specifications.

Laser Alignment

For laser alignment applications consider the all new LAKIT series laser alignment kit. Kits include a 918D series semiconductor detector or 818P thermopile, 1917-R power meter, post, post holder and clamping fork all at an excellent price.

LAKIT-HEP-30W includes an 818P-030-18HP, 1917-R, post, post holder and clamping fork all at an affordable price.

Output power of most Excelsior lasers can be measured by 918D series sensors by expanding the beam and reducing the output power density (maximum limit for 918D-SL-OD3 is 2 W/cm^₂)
Notes
¹ can measure the output power up to 2 minutes of operation
