LOPF-25C-736 25 mm Diameter Mounted Longpass Filter; t=3.5mm 761-850nm

OptoSigma's LOPF-25C-736 is a 25 mm diameter Longpass Filter, designed for use in optical systems where light of specific wavelengths needs to be isolated or blocked. This filter has a cut-on wavelength of 736 nm, meaning it allows light at wavelengths greater than or equal to 736 nm to pass through while blocking lighter wavelengths.

The filter is 3.5 mm thick and is made of UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. The filter's coating, Opt LOPF-736, is applied to both the front and back surfaces, further enhancing its performance.

This filter is shaped as a Thin Lens, which is beneficial in systems where a flat filter might introduce unwanted aberrations. The circular geometry of the filter, with a diameter of 25 mm, ensures easy integration into various optical setups.

The LOPF-25C-736 is currently in stock and available for purchase through the OptoSigma website. For more information, you can refer to the provided weblink.
