When and Why to use an IR corrected lenses?
Use a color day & night or monochrome cameras for the IR corrected lenses.
Regular color cameras will not be affected by the IR corrected lens. When using
the
color day/night or monochrome cameras, nearly any outdoor, as well as some
indoor applications, will require, or at least benefit from using IR corrected
lenses.
This is because many natural light sources also contain infrared light, lighting
changes with a higher infrared, lower infrared, or without infrared at all.
When using ordinary lenses, the result is a blurred, or in a worst case scenario,
a completely unfocused picture.
