87-056 12.5 x 17.6 mm Fluorescence Dichroic Filter 635nm

The 87-056 is a high-quality dichroic filter, designed and manufactured by Edmund Optics, a leading vendor in the optical industry. This filter, measuring 12.5 x 17.6 mm, is specifically engineered for fluorescence applications, with a cut-on wavelength of 635nm.

The filter is made from a unique material, UVFS MAL-1965, which ensures optimal performance in its designated applications. The rectangular base shape of the filter allows for easy integration into various optical systems. The filter has a thickness of 1.05mm, providing sufficient durability while maintaining a compact profile.

The 87-056 features a dichroic coating on both the front and back surfaces, specifically the EDM 87-052 coating. This coating is designed to reflect or transmit light depending on the wavelength, making it ideal for separating or combining different wavelengths in an optical system.

The physical data of the filter indicates a cut-on wavelength of 635nm, meaning it begins to transmit light at this wavelength, and a cut-off wavelength of 0, indicating it transmits all wavelengths below this point. This broad transmission range makes it versatile for various fluorescence applications.

The filter is designed in a thin lens shape, which not only contributes to its compactness but also allows for easy integration into optical systems that require lens elements. The filter is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
