Dichroic Color Filter

45° Reflective Dichroic Color Filters

DELN 45° Reflective Dichroic Color Filters are designed to be used at a 45° angle of incidence and will reflect the stated color while transmitting the remaining visible wavelengths.

Each filter provides greater than 98% reflection over the specified color range and greater than 90% transmission of the remaining wavelengths.

0° Dichroic Color Filters

DELN 0° Dichroic Color Filters are commonly used for color separation and contrast enhancement applications. these filters are easily integrated into a variety of existing camera and illumination setups.

Typical configurations include photo enlargers, beam separation, and placing filters in front an imaging lens to selectively isolate spectral regions/colors. If the light source is already colored (i.e., red LEDs), then a filter in front of the lens can be used to filter out unwanted ambient light.
