Description
1 / 3
The lters of the detectors determine the frequency range of the infrared radiation
which is detected by the sensitive element of the sensor. The wavelength range of the
lters is mainly dened by the target application. The lters are primarily characteri-
zed by their centre wavelength and the full width at half maximum.
Micro-Hybrid Electronic GmbH oers the following dierent types of lters:
a) Narrow band pass lters (NBP)
b) Specic lters provided by the customer
Not all lters can be combined with all detectors oered by MHE due to their dierent
geometrical dimensions and environmental durability. Please conrm your selected
lters with MHE before you nally order.
