NIST will supply the customer with a Hamamatsu model S2281 windowed silicon photodiode characterized in the visible to near-IR spectral region. The spectral responsivity of the photodiode is measured from 300 nm to 1100 nm in 5 nm steps. The 1 cm2 photosensitive area is underfilled for the measurements with a beam from 1.1 mm x 1.1 mm up to 2 mm x 2 mm. The spectral responsivity is measured at radiant power levels of less than 1 μW. The bandpass of the measurement is 4 nm. The spatial uniformity of responsivity over the photosensitive area is also measured at 500 nm.
