Description

The OPTOMAN PP-IRFS-25.4-2.0-DM84-AR130 is a high-performance dichroic mirror designed for efficient wavelength separation in advanced photonics and laser systems. Manufactured with an IR fused silica (Suprasil 300) substrate and precision ion beam sputtered (IBS) coatings, this 25.4 mm diameter optical component provides high reflection in the 640–780 nm wavelength range while transmitting the 1550–2500 nm infrared spectrum.

Featuring a high-reflectivity coating optimized for p-polarized light and broadband transmission performance, this dichroic mirror enables reliable beam combining and separation with low optical losses. Its high surface quality, excellent flatness, and durable IBS coating technology make it suitable for demanding laser, scientific, and industrial optical applications requiring long-term spectral stability.

The optic features a 17° angle of incidence design, >98% reflectance at 640–780 nm, and >95% transmission from 1550–2500 nm, making it an effective solution for visible-to-infrared wavelength management.
