The 919P-040-50 is a thermopile sensor with a broadband absorber for measuring continuous power up to 35 W and pulsed energy up to 200 J. It has an active diameter of 50 mm and a spectral response from 0.19 to 11 µm. The sensor includes a DB15 connector and internal EEPROM for calibration data, and uses a heat sink for cooling. It measures 90 mm in diameter and 33 mm in depth, and weighs 1.32 lb (0.6 kg). Calibration uncertainty is ±1.9%, with repeatability of ±0.5% and linearity of ±1%. The maximum average power density is 10 kW/cm², and maximum energy density is 0.3 J/cm² for pulses under 100 ns. It is compatible with Newport power meters including the 843-R, 1919-R, and 2938-R.
The 919P-040-50 is a large aperture thermal sensor measuring up to 35W continuously and 150W with a 3 minute limit. Its BB absorber type is spectrally flat and covers the wavelength range of 190 nm to 11 µm. It has an aperture of 50 mm and can measure power from 300 mW to 35 W and single shot energy from 100 mJ to 200 J. It has a 1/4-20 tapped hole for post or plate mounting and includes a 2.25 inch long 1/2 inch diameter post with a 1/4-20 tapped hole on both ends.
