Optical Mirror Choice Guide

Review

Optical components optical mirrors are most likely the most often used optical components on your laboratory, and their quality, functionality, and reliability are crucial to the achievement of your experimentation. That is why we offer a number of mirrors so that you can be sure to get exactly what you want. When deciding upon an Optical Mirror, remember that the reflectivity, laser damage resistance, and coat durability.

Metallic Coatings

Broadband metallic coated mirrors are great general-purpose mirrors since they may be used within a really broad spectral range between 450 nm to 12 µm. Their thinner coating, but makes them more prone to harm, and particular care has to be taken when cleaning. Al coating optical mirror is a widely used one.

Dielectric Coatings

Dielectric mirrors provide greater reflectivity over a wide spectral selection of a few 100 nm. Their coating is much stronger, which makes them easier to wash, and more resistant to laser damage. We provide broadband dielectric mirrors which are best for general laboratory use in addition to mirrors specially for high-power Nd:YAG programs at 1.064 µm and 532 nm and DUV and UV software.

Ultrashort-Pulse Program Coatings

Dielectric mirror coatings may cause substantial dispersive consequences for ultrashort pulses. The dispersion of this substance and also the interference effects between the layers lead to rapid phase variations at particular wavelengths. Considering that the group delay is about the slope of the phase variant, these wavelength regions introduce substantial group-delay mistakes that may expand and distort your own pulse. Therefore, for programs that need steering ultrashort pulses, like the ones made by Ti:Sapphire lasers we propose using our silver-coated mirrors, that have minimum phase distortion.
