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. They're also insensitive to polarization and angle of incidence, and supply a continuous phase shift, which makes them suitable for ultrashort-pulse programs. Their thinner coating, however, makes them more prone to harm, and particular care has to be taken when cleaning.

Dielectric mirrors provide greater reflectivity over a wide spectral assortment of a few 100 nm. Their coat is 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 the substance along with 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. There are many optical mirrors on our website, including customized shape aluminum mirrors. Welcome to browse them.

We offer a wide selection of mirror types, including spherical mirrors, parabolic mirrors, elliptical mirrors, flat mirrors, and more, in various shapes, sizes, coatings, and substrates to meet your specific requirements.

Of the wide option of coatings we offer, here are the most common:

1. Aluminum & protected aluminum, the most common coating, up to 98% of reflection from the near UV to IR.
2. Silver coating offers higher reflectivity in the visible range, up to 99.9%. However, the silver coating is less stable than aluminum as it is more sensitive to external environments.
3. Gold coating is often the preferred choice for IR mirrors, as it offers better heat dissipation (especially interesting in the thermal infrared range) and is much more stable than aluminum and silver to external elements.
4. Dielectric coating, refers to thin film deposition of material with specific optical characteristics, are particularly used for custom coating on specific wavelengths. They also have a higher LIDT (resistance to power lasers) than metal coatings.

Our team of experts is always available to assist you in choosing the best optical mirrors for your application, and we are committed to providing excellent customer service and support throughout the ordering and delivery process.
