69-900 25.2 x 35.6 mm Dichroic Longpass Filter; t=1.05mm 550nm

The 69-900 is a Dichroic Longpass Filter, measuring 25.2 x 35.6 mm with a thickness of 1.05mm, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed to transmit light at wavelengths above 550nm, making it ideal for applications that require the separation of longer wavelengths from shorter ones.

The filter boasts a unique dichroic coating on both the front and back surfaces, identified as EDM 69-867. This coating is specifically designed to reflect or transmit light depending on its wavelength, enhancing its longpass filtering capabilities. The 69-900 is cut on at 550nm, meaning it starts to transmit light at this wavelength, and there is no specified cut-off wavelength, indicating that it continues to transmit all longer wavelengths.

The filter is rectangular in shape and made from UVFS MAL-1965 material, a common choice for optical components due to its excellent optical properties. It is designed to fit into systems with thin lens configurations. The filter's physical data, including its dimensions and material, are meticulously controlled during manufacturing to ensure consistent performance and compatibility with other optical elements.

According to the vendor's website, the 69-900 is currently in stock, indicating its availability for immediate use in your optical systems.
