LP02-442RE-25 25 mm Dia. 442nm RazorEdgeUltrasteep Long-Pass Edge Filter by Semrock
The LP02-442RE-25 is a Longpass Filter from Semrock, designed with a 25 mm diameter and a thickness of 2 mm. This filter is specifically engineered for applications that require sharp cut-on characteristics and high transmission at longer wavelengths.
The filter's primary function is to block light below a specified wavelength while allowing light at longer wavelengths to pass through. In this case, the LP02-442RE-25 is designed to cut on at 442 nm, effectively blocking all light of shorter wavelengths. The cut-off wavelength is 0 nm, indicating that no light of any wavelength shorter than 442 nm will pass through the filter.
The filter's coating plays a crucial role in its performance. Both the front and back surfaces of the filter are coated with the Semrock LP02-442RE coating, which is specifically designed to provide the sharp cut-on characteristics and high transmission at longer wavelengths.
The LP02-442RE-25 is available from Semrock and is currently in stock. For more information, including pricing and detailed specifications, please refer to the product's webpage on Semrock's website.
