Cylindrical Lenses Types of Cylindrical Lenses. A cylindrical lens is characterized by both its focal length and its geometry. They can be square, circular, or rectangular. A plano concave cylindrical lens will expand light on a single axis. It is also known as a negative cylindrical lens, and is used for one-dimensional image compression, anamorphic beam shaping, and laser line generation. A plano convex cylindrical lens focuses light on one axis, and can also be used to magnify an image in one direction... (read more)Browse Optical Lenses Datasheets for Avantier Inc. -

Acylindrical Lenses Benefits of Acylinder Lenses. An acylindrical lens is designed to be highly efficient and to deviate from a true cylinder in such a way as to minimize the optical aberrations in a given system. Using acylinder lenses in a system often provides the opportunity to reduce the number of optical components, thus decreasing the size and weight of an optical system. Acylinder lenses also provide ideal collimation and the sharpest possible line focus in many circumstances. Applications of Acylindrical...

UV lenses Special Considerations for UV Lenses. Although UV lenses perform in a similar way to other lenses and are used in similar applications, there are some important considerations to keep in mind when working with UV optics. Scattering, dispersion effects, and laser damage and degradation are all important issues to be aware of when designing your UV setup. Scattering effects can occur anywhere on the spectrum, but they 're especially pronounced when working in UV. This is directly related...

Germanium Lenses Our germanium lenses also come with BBAR (broadband anti-reflection) coatings, which further enhance their performance, particularly in the desired wavelength range of 3-12 mm. These coatings maximize light transmission, reaching up to 95% in some cases. Incorporating germanium transmits, which is a unique characteristic of this material, these lenses excel in mid-infrared light applications. The inclusion of AR coatings further boosts their transmission capabilities, allowing for superior... (read more)Browse Aspheric Lenses Datasheets for Avantier Inc. -
