69-892 25 mm Dia. Dichroic Longpass Filter; t=1.05mm 700nm
The 69-892 is a 25 mm diameter Dichroic Longpass Filter, manufactured by Edmund Optics. This filter is designed with a thickness of 1.05mm and features a cut-on wavelength of 700nm. It is circular in shape and constructed from UVFS material, identified as MAL-1965.
The filter's primary function is to transmit light at wavelengths above 700nm while reflecting or absorbing wavelengths below this point. This makes it ideal for applications that require the separation of specific wavelength ranges.
The 69-892 is coated with EDM 69-870 on both the front and back surfaces, enhancing its performance and durability. Its thin lens shape ensures minimal distortion and maintains the integrity of the light path.
This filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
