69-212 25.2 x 35.6 mm Dichroic Shortpass Filter; t=1.05mm 400nm
The 69-212 is a Dichroic Shortpass Filter, measuring 25.2 x 35.6 mm, with a thickness of 1.05mm, sourced from Edmund Optics. This filter is designed to reflect shorter wavelengths and transmit longer wavelengths, making it ideal for applications that require the separation of light based on wavelength.
The filter's physical data includes a cut-on wavelength of 0 nm and a cut-off wavelength of 400 nm. This means that it will begin to transmit light at 400 nm and block all wavelengths shorter than this. The filter's coating, both on the front and back, is EDM 69-176, which is a dichroic coating designed for high transmission and reflection efficiency in its specified wavelength range.
This filter is rectangular in shape and has a base shape of a thin lens. It is made from UVFS Mal-1965, a material known for its excellent optical properties. The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status.
