Do all digital camera lenses have infrared filters?
The image sensor of a digital SLR camera can sense infrared rays. In order to avoid the interference of infrared rays on normal imaging light, an infrared cut-off filter is usually installed in front of the sensor. However, some special digital SLR cameras are not equipped with infrared cut-off filters. For example, Canon EOS20Da is an astrophotography camera that can take infrared photos, and Fuji S5UV/IR is a digital camera that can take infrared and ultraviolet rays for medical treatment and criminal investigation.
Can be imaged, not visually.
