1 Introduction
Optical System
Grating and Diode Array
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.
The diode array is a series of 1024 individual photodiodes and control circuits
located on a ceramic carrier. It has a wavelength range from 190 – 640 nm and
the sampling interval is ∼0.5 nm.
