Semrock's LP02-830RU-25 is a Longpass Filter, designed with a circular shape and a 25 mm diameter. This filter is made of UVFS Mal-1965 material and has a thickness of 2 mm. The filter's primary function is to allow light transmission at wavelengths above 830 nm while blocking wavelengths below this point.
The filter's coating, both on the front and back, is Sem LP02-830RU, which is specifically designed to ensure optimal performance. The physical data of the filter indicates a cut-on wavelength of 830 nm and a cut-off wavelength of 0 nm. This means that the filter starts transmitting light at 830 nm, and there is no lower limit to the wavelength it blocks.
The filter is available from the vendor Semrock and can be found on their website with the catalog number LP02-830RU-25. The link to the product page is valid and indicates that the filter is in stock, ensuring quick delivery for your optical system needs.
