DMLP425R 25 mm x 36 mm Longpass Dichroic Mirror; 425 nm Cut-On

The DMLP425R is a 25 mm x 36 mm rectangular dichroic mirror, sourced from the renowned optical component manufacturer, Thorlabs. This mirror is specifically designed for longpass applications, with a cut-on wavelength of 425 nm.

The mirror's geometry is thin and rectangular, with a width of 36 mm and a height of 25 mm, making it suitable for a wide range of optical systems. The mirror's thickness is 1 mm, contributing to its robustness and durability.

The mirror's coating is a key feature, with the front surface coated with Thorlabs' proprietary DMLP425 coating. This coating enhances the mirror's performance in longpass applications, ensuring efficient reflection of longer wavelengths and transmission of shorter wavelengths below the cut-on point.

The DMLP425R is available from Thorlabs and is currently in stock, according to the vendor's website. This mirror is part of the UVFS MAL-1965 material category, further attesting to its high-quality construction and performance.
