The 69-881 is a Dichroic Longpass Filter, measuring 12.5 x 17.6 mm with a thickness of 1.05mm, sourced from Edmund Optics. This filter is designed to transmit light at wavelengths above 700nm, making it ideal for applications that require the separation of infrared light from other parts of the spectrum.
The filter features a dichroic coating on both the front and back surfaces, specifically the EDM 69-870 coating. This coating is designed to reflect or transmit light based on its wavelength, enhancing the filter's performance in longpass applications.
The 69-881 is a rectangular filter, with a base shape that is commonly used in optical systems due to its ease of alignment and integration. The filter is made from UVFS Mal-1965, a material known for its optical quality and durability.
This filter is currently in stock and available for purchase through the Edmund Optics website. The catalog number for this item is 69-881. For more information, please refer to the provided weblink.
