45-720 12.5 x 12.5 mm SCHOTT KG1 Heat Absorbing Glass IR Cut-Off Filter 300-2700nm
The 45-720 is a rectangular heat absorbing glass filter, measuring 12.5 x 12.5 mm, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed to absorb and block infrared (IR) radiation within the 300-2700nm wavelength range, making it an ideal choice for applications that require effective heat management and IR rejection.
The filter is made from SCHOTT KG1 glass, a material known for its excellent optical properties and durability. The KG1 glass is cut off at 300nm and cut on at 2700nm, ensuring precise control over the wavelengths that are allowed to pass through. The filter has a thickness of 3mm, providing robustness and stability in its structure.
The 45-720 filter features a coating on both the front and back surfaces, identified as EDM 45-646. This coating enhances the filter's performance by reducing surface reflections and improving transmission, thereby optimizing the overall optical system's efficiency.
The filter's geometry is designed in the shape of a thin lens, which can be beneficial in certain applications where a lens-like component is required. The filter's dimensions and lens shape make it suitable for use in compact optical systems where space is at a premium.
