69-907 25.2 x 35.6 mm Dichroic Longpass Filter; t=1.05mm 900nm
The 69-907 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 above 900nm, making it ideal for applications that require the separation of infrared light from other spectral regions.
The filter is constructed from UVFS Mal-1965 material, a common choice for optical components due to its excellent transmission properties and durability. The rectangular shape of the filter is designed for ease of integration into various optical systems.
The 69-907 features a coating of EDM 69-874 on both the front and back surfaces, enhancing its performance and ensuring consistent results across a wide range of applications. This coating is designed to optimize the filter's longpass characteristics, providing a sharp cut-on wavelength at 900nm.
The filter's physical data further highlights its capabilities. With a cut-on wavelength of 900nm, it efficiently separates infrared light from other spectral regions. The cut-off wavelength is 0, indicating that it allows all wavelengths above 900nm to pass through.
