Introduction
Optical System
Grating The combination of dispersion and spectral imaging is accomplished by using
a concave holographic grating. The grating separates the light beam into all its
component wavelengths and reflects the light onto the photodiode array.
Diode Array The diode array is a series of 1024 individual photodiodes and control circuits
located on a ceramic carrier. With a wavelength range from 190 – 950 nm the
sampling interval is < 1 nm.
