68-653 25 mm Dia. Traditional Coated Infrared (IR) Longpass Filter; t=1mm 2400nm
The 68-653 is a 25 mm diameter Infrared (IR) Longpass Filter, manufactured by Edmund Optics. This filter is designed with a traditional coating, providing excellent performance in the infrared spectrum. The filter features a circular base shape and is made from germanium burnett material, ensuring durability and reliability.
The filter has a wavelength of 588 nm and a thickness of 1 mm. It is designed to cut on at 2400 nm, meaning it allows all wavelengths of light shorter than 2400 nm to pass through while blocking those longer than 2400 nm. The cut off is 0, indicating that it blocks all wavelengths beyond its cut on point.
The 68-653 filter is coated on both the front and back with edm 33-969, a type of coating that enhances its performance and longevity. The filter's shape is that of a thin lens, making it suitable for a wide range of optical applications.
