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. The flat glass used as the light input window is less susceptible to scratches than resin windows,
allowing easy handling.
