LP02-442RU-25 25 mm Dia. 442nm RazorEdgeUltrasteep Long-Pass Edge Filter by Semrock
The LP02-442RU-25 is a Longpass Filter from Semrock's extensive catalog, designed with a 25 mm diameter and a thickness of 2 mm. This filter is specifically engineered for use in applications that require the efficient separation of light based on wavelength.
The LP02-442RU-25 boasts a cut-on wavelength of 442 nm, meaning it begins to transmit light at this point in the spectrum. Conversely, it has a cut-off wavelength of 0 nm, indicating it blocks all wavelengths shorter than 442 nm. This makes it ideal for use in applications where light of a specific wavelength needs to be isolated or blocked.
The filter is coated with Semrock's proprietary RazorEdgeUltrasteep coating on both the front and back surfaces. This coating ensures a sharp transition between the blocked and transmitted wavelengths, providing superior performance compared to traditional longpass filters.
The filter's geometry is defined by its thin lens shape, which is designed to minimize optical aberrations and ensure optimal performance. The LP02-442RU-25 is currently in stock and available for purchase through the Semrock website.
