Pleiger Laser Optics IR filters are made of silicon, germanium, spahir, IR fused silica, and ZnSe. The bandpass filters are usually used for gas anlytics (H2O, ethanol, methanol, formaldehyde, CO2, CO, NO,).
Neutral density filters (gray filters) are placed in front of the sensor to reduce the amount of light on the detector. Long-pass and short-pass filters are used to block out spectral ranges.
