uEye Camera Manual Version 3.80
Filter Types
Every uEye camera has a filter glass in the front flange to prevent the entry of dust particles. Color cameras by default use an IR cut filter, which is required to ensure correct color rendering. The default filter glass in monochrome cameras has no filter effect. Every camera model is available with different filter variants such as daylight cut filters (type DL). The filter type is given at the end of the uEye model name.
The following table shows an overview of the different optical filters used in the uEye cameras:
