Curved Mirror Substrates
Curved mirror substrates are available as plano-concave or plano-convex substrates.
Uncoated Substrates
Curved mirror substrates are available as plano-concave or plano-convex substrates. They differ from plano-concave and plano-convex lenses in their center thickness, which is higher in mirror substrates. This counteracts the possible deterioration of the surface figure resulting from the application of dielectric coatings. Alternatively lenses may also be used.
Mirror substrates are most commonly used in laser resonators. They are equipped with highly reflective or partially reflective coatings.
The majority of mirror substrates are available as BK7 substrates; however, fused silica substrates can also be used for the highest power levels.
All mirror substrates can be manufactured with customer-specific radii of curvature.
Spherical Concave Mirror Substrates
Concave mirror substrates are often used in resonators. This application is very advantageous because the concave surface facilitates a resonator that is easy to adjust. Convex mirror substrates are often used in resonators.
Parabolic Mirror Substrates
LASER COMPONENTS manufactures high quality parabolic mirrors on glass substrates that feature excellent form accuracy and micro surface roughness. Because of these features, the laser mirrors are extremely efficient in laser applications.
In addition to parabolic mirrors, which are primarily used in thin-disc lasers, we have other aspherical surfaces available for the most diverse applications.
