87-064 25.2 x 35.6 mm Fluorescence Dichroic Filter 635nm

The 87-064 is a 25.2 x 35.6 mm Fluorescence Dichroic Filter with a center wavelength of 635nm, sourced from the renowned optical vendor, Edmund Optics. This filter is a crucial component in various optical systems, particularly those involving fluorescence detection and imaging.

The filter is designed with a rectangular base shape, making it compatible with a wide range of optical setups. It is fabricated from UVFS Mal-1965, a material specifically chosen for its optical properties, ensuring high-quality performance. The filter's geometry, including its width of 25.2mm, height of 35.6mm, and thickness of 1.05mm, is meticulously designed to provide optimal optical path length and minimize unwanted reflections.

The 87-064 features a cut-on wavelength of 635nm, meaning it begins to transmit light at this wavelength, while blocking or reflecting wavelengths below this point. This characteristic makes it ideal for applications where specific wavelength selection is required.

The filter's coating is another notable feature. Both the front and back surfaces are coated with EDM 87-052, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission.

In terms of shape, the 87-064 is designed as a thin lens, further enhancing its functionality in optical systems. The filter's availability and in-stock status, as indicated by its valid weblink, make it a readily accessible option for users.
