Optical filters make it possible to control the effect of different types of light on the sensor. These filters are defined by their characteristic filter curve, which shows how much light they transmit or absorb. By understanding this curve, photographers can better adjust light sources and sensors to achieve the desired effects.

Learn moreColor errors occur because the refractive index of optical glass varies for different wavelengths (colors). This phenomenon is called dispersion. There are two classes of chromatic aberration.
Learn moreIf the sensitivity of the image sensor is to be used in the near infrared range, lenses must be used that have sufficient transmission and imaging performance in this wavelength range (approx. 700-1000 nm).
