UV-grade fused silica offers high transmission in the deep UV and exhibits virtually no laser-induced fluorescence (as measured at 193 nm), making it an ideal choice for applications from the UV to the near IR. In addition, UV fused silica has better homogeneity and a lower coefficient of thermal expansion than N-BK7. The additional UV antireflection coating on these plano-concave lenses is particularly desirable for applications with multiple optical elements. Since approximately 4% of the incident light is reflected at each surface of an uncoated substrate, the application of a UV AR coating improves transmission, which is particularly important in low-light applications, and prevents the undesirable effects (e.g., ghost images) associated with multiple reflections. Plano-concave lenses have negative focal lengths, making them useful for a wide range of applications. They are commonly used to diverge a collimated incident beam; in such cases the collimated light source should be incident on the curved surface to minimize spherical aberrations. Plano-concave lenses, which produce virtual images, are used as the entrance optic in Galilean-type beam expanders; this lens provides the desired divergence and then a doublet is used to recollimate the beam. In optical systems, it is common for researchers to choose their optics carefully so that the aberrations introduced by the positive- and negative-focal-length lenses approximately cancel. Still others use these lenses in pairs to increase the effective focal length of a converging lens. When deciding between a plano-concave lens and a bi-concave lens, both of which cause collimated incident light to diverge, it is usually preferable to choose a plano-concave lens if the desired absolute magnification is either less than 0.2 or greater than 5. Between these two values, bi-concave lenses are generally preferred. Thorlabs offers these plano-concave lenses in sizes ranging from ?6 mm to ?1". Each size is compatible with a multitude of Thorlabs lens mounts. Please see the Mounting Options tab for details.
