Radiation detector

摘要

The invention concerns a radiation detector for detecting radiation having a defined spectral sensitivity distribution ( 14 ) that exhibits a sensitivity maximum at a defined wavelength lambda₀, wherein the radiation detector preferably contains a III-V semiconductor material and particularly preferably comprises at least one semiconductor chip ( 1 ) and at least one optical filter disposed after the semiconductor chip, the semiconductor chip containing at least one III-V semiconductor material and the optical filter absorbing radiation of a wavelength that is greater than the wavelength lambda of the sensitivity maximum.
