Thorlabs' UV-Enhanced Aluminum-Coated Concave Mirrors are designed for light collection, imaging, and focusing applications. These reflective optics focus light without chromatic aberration, making them especially suitable for broadband sources.
These mirrors offer >90% average reflection in the ultraviolet spectral range from 250 - 450 nm. They consist of an N-BK7 substrate with a UV-enhanced protected aluminum coating. With low surface irregularity at 633 nm, these mirrors provide excellent image quality.
All of the mirrors on this page can be mounted by our Precision Kinematic Mirror Mounts.
Please contact Tech Support for custom versions of these optics. Thorlabs also offers dielectric concave mirrors that provide higher reflectivity than metal mirrors at the expense of operating over a more narrow wavelength range.
The shaded regions in the graphs denote the ranges over which we guarantee the specified reflectance. Please note that the reflectance outside of these bands is typical and can vary from lot to lot, especially in out-of-band regions where the reflectance is fluctuating or sloped.
