Quadrant photodiode delivers 5mm active area
OPTO DIODE SXUVPS4 multi-element photodiode detector with a 5mm² active area in a quadrant configuration resists radiation damage from high intensity UV lasers. Devices provide high stability, and can withstand 4 days of exposure to 10 eV 1016 photons/cm2 without degradation in responsivity. Device provides 0.125 to 0.02 A/W over a 10 to 200 nm wavelength range. The large circular detection surface is optimized for precise alignment of lasers with 4 elements, each offering 1.25mm² active area.
