The 818-RAD-UVA is a photodiode-based irradiance and dosage sensor calibrated for the spectral range of 350-450 nm, with an irradiance measurement range of 1.5 µW/cm² to 15 W/cm² and a 2.75 mm clear aperture. It features a cosine-corrected diffuser for accurate angular response up to 70 degrees, and includes a 1.5 m cable with a DB15 connector. The sensor has a maximum power density limit of 50 W/cm² and a thermal coefficient of -0.03%/°C, with calibration uncertainty of ±3.6% (350-400 nm) and ±3.4% (400-450 nm). It is NIST-traceable, certified CE, UKCA, and China RoHS compliant, and measures 35 mm in diameter and 21 mm in height, weighing 0.11 kg. It is compatible with Newport 1919-R, 843-R/843-R-USB, 844-PE-USB, and 845-PE-RS meters.
The 818-RAD-UVA photodiode based sensor is a versatile solution for measuring narrowband and broadband sources, such as LEDs and lasers, in the spectral range without the need to know the exact wavelength, enhancing its flexibility and utility in diverse applications, the sensor facilitates the simultaneous measurement of sources at different wavelengths,
This eliminates the need for precise knowledge of the exact wavelength. Importantly, the measurement of broadband sources, such as LEDs, remains accurate despite variations in source bandwidth or wavelength shift due to heating.
The 818-RAD-UVA and laser radiometer serves as a modern replacement for conventional radiometers, which are typically calibrated for a single wavelength such as 254 nm or 365 nm. This innovative device offers calibration across a wide spectral range, allowing users to input any wavelength within the calibration range.
Designed as a versatile circular geometry photodiode irradiance and dosage sensor, the 818-RAD-UVA features a 2.75 mm aperture and a cosine-corrected diffuser. Its spectral range spans from 350nm to 450nm, and it can measure irradiance within the range of 1.5μW/cm² to 15W/cm².
The sensor comes equipped with a 1.5 meter cable for seamless connection to 1919-R & 843-R/843-R-USB meters with or without PMManager or the 844-PE-USB ,845-PE-RS PC interface.
