Lenses of Normal Quality
Inexpensive substrates for sensor applications or simple imaging tasks.
Uncoated Substrates
Not all applications require the highest quality levels of optics. For such cases, LASER COMPONENTS offers substrates of "normal quality."
These inexpensive substrates are adequate for sensor applications or simple imaging tasks. As always, all optics can be coated at LASER COMPONENTS.
Plano-convex and Plano-concave Lenses
Plano-convex and plano-concave lenses are preferred to biconvex or biconcave lenses because they are less expensive. They are suited for applications in sensor technology or applications with long focal lengths. Their imaging qualities for these tasks are adequate.
Biconvex and Biconcave Lenses
Biconconvex and biconcave lenses are used if a short focal length has to be achieved with a large lens diameter. The refractive power of the lens is achieved by the two radii of curvature rcc and rcx (see also the drawing).
Because both sides of the lens are curved, a single curvature is not as strong as in plano-concave/plano-convex lenses of the same focal length. The aberrations of the biconcave/biconvex lenses are therefore smaller, which is crucial for many applications.
