The 86-698 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 transmit light below a specified wavelength (cut on) and reflect light above that wavelength (cut off).
In this case, the 86-698 filter has a cut on wavelength of 0 nm, allowing all wavelengths to pass through, and a cut off wavelength of 1150 nm, reflecting or blocking all wavelengths above this point. This makes it ideal for applications where short wavelengths need to be isolated or emphasized, such as in certain imaging or spectroscopy setups.
The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent transparency and durability. It features a Thin Lens shape, which is designed to minimize optical aberrations and distortions, further enhancing its performance in a variety of applications.
The front and back surfaces of the filter are coated with EDM 86-680, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and increasing transmission, ensuring optimal light passage through the filter.
