(Advanced Photonix: Camarillo, CA) –- Advanced Photonix, a division of OSI Optoelectronics and a leading provider of optoelectronics solutions, has introduced two new silicon carbide (SiC) broadband UV photodiodes for ultraviolet source monitoring. The APX-SC0010 features a 1 mm² active area, and the APX-SC00025 features an active area of 0.25 mm². The robust, solar-blind devices operate in the spectral range from 200 nm to 380 nm and can completely block out any wavelengths outside this range, including the visible spectrum.

The new SiC photodiodes have been specially designed for UV index monitoring, dose measurement, and flame detection applications. With a broadband (UVA+UVB+UVC) sensitivity peaking at 275 nm, excellent UV responsivity characteristics, and very low dark current even at elevated temperatures, these devices are ideal for ultraviolet radiation detection tasks requiring outstanding visible wavelength blocking. They can operate at high temperatures and are responsive between 200 nm and 400 nm, and not responsive to longer wavelengths because of the wide band gap.
