45° Dichroic Mirror | 638nm R>97%, 450/520-530nm T>95%, 1.1mm Thickness

This precision 45-degree dichroic mirror is engineered for beam combining and separation applications, delivering high reflection at the 638nm band and high transmission across 450nm and 520–530nm bands at a 45 degree angle of incidence. As a core product in our dichroic mirrors portfolio, it provides sharp spectral edges and low insertion loss to maintain signal integrity in compact optical systems. OPTOStokes maintains an extensive in-stock selection of standard specifications, alongside full custom coating services to match the exact requirements of your optical assembly.

Technical Specifications

Applications

This 45-degree dichroic mirror is widely deployed in machine vision systems and optical inspection setups, where precise wavelength separation directly improves imaging contrast and detection accuracy. It is also ideal for beam combining in multi-wavelength illumination modules, laser systems, and analytical instruments. Its consistent spectral performance across production batches ensures reliable results in both prototype validation and high-volume OEM integration, helping engineers reduce alignment work and improve overall system stability.
