Dichroic Filter
Dichroic filters block certain wavelengths. They can also be used in another way: different wavelengths can be divided but also combined.
High quality dichroic filters with low-loss may need up to 30 hours in the coating process. In order to achieve a high-quality surface, it is recommended to use a thick substrate.
Nevertheless, there has to be a compromise, because a 45° dichroic filter refracts the beam in the substrate which then causes drifts.
