LP02-248RS-25 25 mm Dia. 248nm RazorEdgeUltrasteep Long-Pass Edge Filter by Semrock

The LP02-248RS-25 is a Longpass Filter, specifically designed for use in optical systems that require precise wavelength control. This filter, sourced from the reputable vendor Semrock, is a circular shape with a diameter of 25 mm and a thickness of 2 mm, making it suitable for a wide range of applications.

The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. The LP02-248RS-25 is designed to cut on at 248 nm and cut off at 0 nm, providing a sharp transition between the blocked and transmitted wavelengths. This is achieved through the use of Semrock's proprietary RazorEdgeUltrasteep coating on both the front and back surfaces.

The coating on the front surface is Sem LP02-248RS, while the back surface is coated with the same material. This ensures consistent performance from both sides of the filter, making it ideal for use in applications where the direction of light may vary.

The filter's geometry is that of a Thin Lens, which can be beneficial in certain optical configurations. The catalog number for this item is LP02-248RS-25, and it can be found on Semrock's website, where it is currently in stock.
