69-902 25.2 x 35.6 mm Dichroic Longpass Filter; t=1.05mm 650nm

The 69-902 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 longer than 650nm, making it ideal for applications that require the separation of infrared light from visible light.

The filter's Dichroic properties are achieved through a specialized coating on both the front and back surfaces, identified as 'edm 69-869'. This coating ensures high transmission efficiency for longer wavelengths while effectively blocking shorter wavelengths. The 650nm cut-on wavelength is a crucial specification, indicating the point at which the filter begins to transmit light.

The filter's rectangular shape and thin lens design contribute to its versatility, allowing it to be easily integrated into various optical systems. The vendor, Edmund Optics, provides a catalog number (69-902) for easy identification and ordering. The filter's current status is 'in stock', as indicated by the weblink, ensuring quick delivery for your optical project needs.
