Features
Thorlabs' Broadband Dielectric Concave Mirrors are designed for light collection, imaging, and focusing applications. These reflective optics focus light without introducing chromatic aberration, making them especially suitable for broadband sources. All of the mirrors on this page can be mounted by our Precision Kinematic Mirror Mounts. Thorlabs also offers metallic concave mirrors that operate over a broader wavelength range at the expense of lower reflectivity. Please contact Tech Support for custom versions of these optics. These plots show the reflectivity of our -E01 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.
Concave Mirror Selection GuideThorlabs offers concave mirrors with both metallic and dielectric stack reflective coatings. Metallic-coated mirrors offer relatively high reflectivity (90-95%) over a wide wavelength range, while dielectric-coated mirrors provide even higher reflectivity (>99%) but over a smaller wavelength range. See the table to the right for an overview of the various coatings we offer for our concave mirrors. All coating options are available on optics with diameters ranging from Ø1/2" to Ø75 mm. Metallic mirrors are available with focal lengths from 9.5 - 1000 mm, while dielectric mirrors are available with focal lengths from 12 - 1000 mm. Below are reflectivity plots for our complete line of concave mirrors. To view our selection of mirrors available with a particular coating, either click on the graphed line of interest or the corresponding coating name in the legend. Graphs are shown for an angle of incidence (AOI) of 8 degrees, which is the recommended angle at which to use a concave mirror. Click on a particular graphed line or the corresponding name in the legend to view concave mirrors with that coating option.
