69-891 25 mm Dia. Dichroic Longpass Filter; t=1.05mm 650nm
The 69-891 Dichroic Longpass Filter is a circular filter, 25 mm in diameter, with a thickness of 1.05 mm, sourced from Edmund Optics. This filter is designed to transmit light with wavelengths longer than 650 nm, 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 69-869 coating. This coating is designed to reflect or transmit light based on its wavelength, enhancing the filter's performance in longpass applications.
The 69-891 filter is designed for use with thin lenses, making it a versatile option for a wide range of optical systems. It is currently in stock and available for purchase through the Edmund Optics website.
