69-865 12.5 mm Dia. Dichroic Longpass Filter; t=1.05mm 450nm

The 69-865 Dichroic Longpass Filter is a high-quality optical component manufactured by Edmund Optics, a leading global provider of optical components. This filter is designed with a diameter of 12.5 mm and a thickness of 1.05 mm, making it suitable for a wide range of optical applications.

The filter is a Dichroic type, which means it reflects one wavelength and transmits another. In this case, the cut-on wavelength is 450 nm, indicating that it begins to transmit wavelengths of 450 nm and longer. The cut-off wavelength is 0 nm, meaning it continues to transmit all wavelengths beyond 450 nm. This makes it an ideal choice for applications that require the separation of shorter wavelengths from longer ones.

The filter's material ID is UVFS MAL-1965, and it comes with coatings on both the front and back surfaces, specifically EDM 69-865. The geometry of the filter is that of a thin lens, which contributes to its versatility in various optical systems.

The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status. For more detailed information, users are encouraged to visit the provided weblink.
