87-286 25.2 x 35.6 mm Multi-Edge Fluorescence Dichroic Filter 444/521/608nm

The 87-286 is a Multi-Edge Fluorescence Dichroic Filter, manufactured by Edmund Optics, measuring 25.2 x 35.6 mm. This filter is designed to reflect and transmit specific wavelengths of light, making it ideal for applications involving fluorescence microscopy and other multi-wavelength optical systems.

The filter's primary function is to reflect light at 444nm, 521nm, and 608nm, while allowing all other wavelengths to pass through. This is achieved through a specialized coating, denoted as 'edm 87-286' on both the front and back surfaces. The filter's base shape is rectangular, and it has a thickness of 1.05mm, providing durability and stability in its mounting.

The physical data of the filter indicates a cut-on wavelength of 444nm and a cut-off wavelength of 0nm. This means that the filter begins to transmit light at 444nm and continues to do so for all longer wavelengths. The filter's geometry, including its width of 25.2mm and height of 35.6mm, is designed to fit standard optical mounts and systems.

The catalog number for this item is 87-286, and it can be found on the Edmund Optics website, where it is currently in stock. The link to the product page is provided for convenience. This filter is part of the UVFS MAL-1965 material ID, further indicating its suitability for fluorescence applications.
