SENSORS for PHOTOMETRY & RADIOMETRY

UDT Instruments offers a wide range of photosensors for both photometric and radiometric applications. Basic sensors, used alone, are suitable for illuminance or irradiance measurements. Each type of sensor can be combined with various types of optical adaptors to form sensor head assemblies suitable for measurements of flux, intensity, luminance, or radiance.

UDTi photosensors and sensor heads are offered in three different mechanical configurations: Sensors from the Standard Series adapt for use with most accessories. The Miniature Series includes a similar range of sensors with a smaller-diameter package, compatible with UDTi's line of integrating sphere accessories. The Low-Profile Series is designed for applications with limited mechanical clearance.
