OSI annular quadrant silicon photodiodes have typical peak wavelength of 980 nm

Annular quadrant silicon photodiodes operate between 350 and 1100 nm, and are used for backscatter reflectivity measurements. The active area on each element is 1.6 and 19.6 mm², respectively, with a spectral range from 190 to 1100 nm and a typical peak wavelength of 980 nm.
