69-899 25.2 x 35.6 mm Dichroic Longpass Filter; t=1.05mm 500nm

The 69-899 is a Dichroic Longpass Filter, measuring 25.2 x 35.6 mm, with a thickness of 1.05mm, sourced from Edmund Optics. This filter is designed to transmit light at wavelengths longer than 500nm, making it ideal for applications that require the separation of visible and infrared light.

The filter is made from UVFS Mal-1965 material, a common choice for optical components due to its excellent transmission properties and durability. The rectangular base shape ensures easy integration into various optical systems.

The 69-899 features a coating of EDM 69-866 on both the front and back surfaces, enhancing its performance and longevity. This coating helps to reduce surface reflections and improve transmission, ensuring optimal performance in your optical setup.

The physical data of the filter indicates a cut-on wavelength of 500nm, meaning it begins to transmit light at this point in the spectrum. The cut-off wavelength is 0nm, indicating that it transmits all wavelengths longer than the cut-on point.

This filter is available in a Thin Lens shape, providing versatility in its application. The catalog number, 69-899, can be used to easily locate this item on the Edmund Optics website, where it is currently in stock.
