PHOTODIODE Si PIN photodiode S3994-01 Si PIN photodiode for optical power meters S3994-01 is a Si PIN photodiode designed for optical power meters. Compared to the previous type (S3994), S3994-01 has an improved anti-reflection film and sensitivity optimized for detection of violet laser beams. The flat glass used as the light input window is less susceptible to scratches than resin windows, allowing easy handling.
