This is a robust device consisting of one photodiode. The photodetector offers performance which is characteristic to a single photodiode: large field of view and active area, compact construction and comfortable handling. Due to high back-reflectance, the quantum efficiency of one-element photodetector is significantly less than unity. Nevertheless, by knowing photodiode antireflection coating thickness the spectral reflectance and responsivity can be modelled at any incidence angle and state of beam polarisation. The photodetector consisting of one photodiode can successfully used in the simple measurements of optical quantities.
