5.13 Infrared Cut-Off Filters—Cased Models
Note:
Board-level color models do not have infrared cut-off filters.
Color camera cased models are equipped with an additional infrared (IR) cut-off filter. This filter can reduce sensitivity in
the near infrared spectrum and help prevent smearing. The properties of this filter are illustrated in the results below.

In monochrome cased models, the IR filter is replaced with a transparent piece of glass.
