The 818-RAD is a photodiode irradiance and dosage sensor with an 8mm clear aperture and cosine-corrected diffuser, designed for measuring irradiance from 100 nW/cm² to 250 mW/cm² across a spectral range of 200-850 nm. It features auto-ranging across seven irradiance scales, a 500 samples per second dosage sampling rate, and a 1.5 m cable with a DB15 connector. The sensor has a maximum power density of 10 W/cm², a noise level of 5 nW/cm², and a thermal coefficient of -0.03%/°C. Its dimensions are 35 mm in diameter by 21 mm in height, weighing 0.11 kg. It is NIST-traceable calibrated with ±3.4% uncertainty at 400-850 nm, and meets CE, UKCA, and China RoHS standards. Compatible power meters include the 1919-R, 843-R/843-R-USB, 844-PE-USB, and 845-PE-RS.
The 818-RAD Irradiance and Dosage Sensor replaces traditional radiometeric sensors which are calibrated to specific wavelength or bands such as UVA, UVB, UVC, or Photopic. It is deal to measure the radiant flux per unit area for a large area uniform light source. It offers calibration over a broad spectral range, which the user can access by entering any wavelength in the calibration range. 818-RAD is a general purpose circular geometry photodiode with an 8mm aperture and a cosine corrected diffuser. Its spectral range is 200 - 850 nm and its irradiance measuring range is 100 nW/cm² - 250 mW/cm². The sensor has a 1.5 meter length cable for connecting to a power meter. It has a 1/4-20 tapped hole for post or plate mounting. The product includes a 2.25 inch long 1/2 inch diameter post with a 1/4-20 tapped hole on both ends.
