Dichroic Filters, also known as Interference Filters, are highly precise color filters that transmit light within a narrow range of colors while reflecting the unwanted portions. These filters split light into two components: one component is transmitted, and the other is reflected. This unique ability allows users to select spectral regions of interest and determine whether the separated light spectrum should be utilized or discarded.
