Products/ Spectrometer Modules/ PGS Series
|
PGS stands for Plane Grating Spectrometer,
meaning that a planar grating is used in conjunction
with lenses to provide the necessary imaging. Due to
the superb quality of the gratings (blazed) and the
selected materials / components, high-end spectrometer
modules are created, allowing high flexibility with
respect to customization of spectral ranges and resolutions.
The PGS NIR is available in two standard versions. In
addition, this new series of NIR diode-array based spectrometers
from Zeiss allows to create customized solutions quite
easily.
