66-250 35 x 35 mm N-BK7 45 deg Reflective Magenta Dichroic Filter; t=3 mm 400-465/635/725nm

The 66-250 is a 35 x 35 mm dichroic filter with a 45-degree angle of incidence, designed and manufactured by Edmund Optics. This filter is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of optical applications.

The filter's primary function is to reflect and transmit specific wavelengths of light. It is designed to reflect light in the 400-465nm and 725nm ranges while transmitting light in the 635nm range. This makes it particularly suitable for applications that require the separation or manipulation of specific wavelengths, such as in spectroscopy or laser technology.

The filter has a thickness of 3mm, providing durability and stability. It features a thin lens shape, which is designed to minimize optical aberrations and distortions. The coating on both the front and back surfaces of the filter is EDM 66-244, a proprietary coating developed by Edmund Optics for enhanced performance and durability.
