LOPF-25C-635 25 mm Dia. Mounted Longpass Filter; t=3.5mm 660-1200nm

The LOPF-25C-635 is a Longpass Filter with a 25 mm diameter, designed and manufactured by OptoSigma. This filter is specifically engineered for use in optical systems that require long-wave pass filtering capabilities within the 660-1200nm range. The filter is mounted and has a thickness of 3.5mm, providing a robust and stable platform for integration into various optical setups.

The filter's primary function is to allow light transmission above a specified wavelength (cut on wavelength) while blocking or significantly reducing light transmission below that wavelength (cut off wavelength). In this case, the cut on wavelength is 635nm, and the cut off wavelength is 0nm, indicating that this filter will pass all wavelengths above 635nm.

The LOPF-25C-635 features a Thin Lens shape, which is beneficial in applications where minimal optical path difference is required. The filter's coating, both on the front and back, is 'opt lopf-635', which contributes to its longpass filtering capabilities.
