69-205 25 mm Dia. Dichroic Shortpass Filter; t=1.05mm 650nm

The 69-205 is a Dichroic Shortpass Filter, boasting a 25 mm diameter and a thickness of 1.05mm, specifically designed for a cut-off wavelength of 650nm. This filter is sourced from the reputable vendor, Edmund Optics, and is a part of their extensive catalog of optical elements.

The filter's primary function is to reflect wavelengths shorter than the specified cut-off while transmitting wavelengths longer than this value. This makes it an ideal component for applications where the removal of specific wavelength ranges is required.

The 69-205 features a Base Shape of Circular, with a geometry that includes a 25mm diameter, providing a substantial surface area for light interaction. The thickness of 1.05mm is optimized for its functionality and is identified as UVFS Mal-1965 in the Material ID.

The coating of the filter is consistent on both the front and back surfaces, utilizing the EDM 69-181 coating. This coating enhances the filter's performance, ensuring efficient reflection and transmission of the designated wavelength ranges.

The filter's physical data includes a cut-on of 0, indicating that it begins transmitting from the specified cut-off wavelength without any initial reflection. The shape of the filter is Thin Lens, which is ideal for applications requiring minimal optical path deviation.
