Dichroic optical filters consist of thin film dielectric coatings on glass and exhibit sharp transitions between transmitted and reflected wavelengths. Dichroic filters are similar to traditional interference filters but differentiate themselves by reflecting all unwanted wavelengths. Consequently our dichroic range also offers minimal absorbance characteristics.
Our dichroic filters are available in longpass, shortpass, bandpass, bandblocking and colour correction types over a range of wavelengths. Dichroic shortpass and longpass filters can also act as hot and cold mirrors respectively.
Dichroic filters can divide natural light from a certain wavelength into two parts, one of which passes through, and the other is reflected or absorbed. Filters that allow longer wavelengths of light to pass through are referred to as long wave pass filters, and filters that allow shorter wavelengths of light to pass through are referred to as short wave pass filters.
The desired spectral range can be achieved by using different dichroic filters.
