The 86-694 is a Dichroic Shortpass Filter, measuring 25.2 x 35.6 mm with a thickness of 1.05mm, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed to selectively transmit light below a specified wavelength while reflecting light above that wavelength, making it ideal for applications that require the separation of different spectral bands.
The filter's primary wavelength is 588nm, and it features a cut-on wavelength of 0nm and a cut-off wavelength of 950nm. This specifications make it suitable for use in systems where short wavelengths need to be isolated or passed, while longer wavelengths are blocked. The filter's Dichroic properties are achieved through a specialized coating on both the front and back surfaces, specifically the EDM 86-676 coating.
The 86-694 filter is available directly from Edmund Optics, and the vendor's website indicates that it is currently in stock.
