Nov. 17, 2014 – Camarillo, CA – Opto Diode (www.optodiode.com), a division of ITW, introduces the SXUVPS4, a new multi-element detector with a 5 mm² active area in a quadrant configuration. Designed to resist radiation damage from high intensity UV lasers, the SXUVPS4 photodiodes are ideal for laser alignment applications. Offering unmatched stability, the SXUV series of photodiodes are the only commercially available detectors that can withstand 4 days of exposure to 10 eV 10¹⁶ photons/cm² without degradation in responsivity.

The new photodiode features excellent responsivity providing 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 1.25 mm² active area. The compact TO-5 package allows for easy integration into new or existing systems.

As with all Opto Diode products, the new quadrant photodiodes are designed to maximize measurement repeatability and reliability.
