Thorlabs' Broadband Dielectric Concave Mirrors are designed for a wide variety of light collection, imaging, and focusing applications. These reflective optics focus light without chromatic aberration, making them especially suitable for broadband sources. 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.
These plots show the reflectivity of our -E02 dielectric coating for a typical coating run. The shaded region in each graph denotes the spectral range over which the coating is highly reflective. Due to variations in each run, this recommended spectral range is narrower than the actual range over which the optic will be highly reflective. If you have any concerns about the interpretation of this data, please contact Tech Support. For applications that require a mirror that bridges the spectral range between two dielectric coatings, please consider a metallic concave mirror.
