The 919P-250-35 is a thermopile sensor designed for measuring optical power up to 250 W with a spectral range of 0.19 to 11 µm. It features a broadband absorber, an active diameter of 35 mm, and active area of 9.62 cm², with fan cooling. The sensor supports maximum continuous power of 250 W, maximum energy of 300 J, and maximum average power density of 10 kW/cm². Energy density limits are 0.3 J/cm² for pulses under 100 ns, 5 J/cm² for 0.5 ms, 10 J/cm² for 2 ms, and 30 J/cm² for 10 ms at 1064 nm. Calibration uncertainty is ±1.9%, repeatability ±0.5%, linearity ±1%, and uniformity ±2%. Dimensions are 64 mm × 64 mm × 95 mm, and weight is 0.88 kg. The sensor includes a DB15 connector and internal EEPROM for calibration data.
The 919P-250-35 Fan Cooled Thermopile Sensor is a general purpose thermal sensor measuring optical power up to 250 W. It's BB type absorber is spectrally flat and covers the wavelength range 190 nm to 11 µm. It has an active diameter of 35 mm and can measure continuous optical power from 150 mW to 250 W and single shot energy from 50 mJ to 300 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.
