69-888 25 mm Dia. Dichroic Longpass Filter; t=1.05mm 500nm

The 69-888 is a Dichroic Longpass Filter, boasting a 25 mm diameter and a thickness of 1.05mm, sourced from the reputable vendor, Edmund Optics. This filter is designed to transmit light with wavelengths longer than 500nm, making it ideal for applications that require the separation of visible and infrared light.

The filter's geometry is meticulously crafted, with a 25mm diameter ensuring a wide field of view and the 1.05mm thickness providing robustness and durability. The cut-on wavelength is set at 500nm, indicating that it begins to transmit light at this point of the spectrum, while the cut-off wavelength is 0nm, meaning it transmits all wavelengths longer than 500nm.

The 69-888 filter features a dichroic coating on both the front and back, specifically the EDM 69-866 coating. This coating enhances the filter's performance by reflecting or transmitting specific wavelengths of light, thereby improving its efficiency and effectiveness in its intended applications.

The filter's shape is that of a Thin Lens, which not only contributes to its compactness but also allows for easy integration into various optical systems. The filter's catalog number is 69-888, and it is currently in stock, as indicated by its weblink status. For more information or to make a purchase, users can visit the provided weblink.
