Plano-convex cylindrical lenses are positive lenses. These plano-convex cylindrical lenses are edged as circular shapes so they can easily be combined with other elements in an optical system. They are typically used either to focus incoming light to a line or to change the dimensions of an image in a single direction. Our Plano-Convex lenses are available in a variety of laser line V-Coat AR coating options. Designed for maximum throughput at the specified laser wavelength, these lenses are ideal for applications utilizing low power HeNe, Diode and Nd:YAG laser sources.

Bi-convex or symmetric-convex lenses have two convex surfaces with identical radii. They have positive focal lengths and form both real and virtual images. They are recommended for virtual imaging of real objects and for positive conjugate ratios from approximately 0.2 to 5 (values are wavelength sensitive). Due to the symmetry, aberrations such as coma, distortion, and chromatic aberration almost exactly cancel out at unit conjugate ratio. Aberrations increase as conjugate ratios depart from unity.

Achromatic lenses are computer optimized to correct for on-axis spherical and chromatic aberrations. They consist of two optical components of different refractive index cemented together to form an achromatic doublet. These lenses are useful in axial imaging aplications where a small spot size is required and for broadband imaging covering the visible spectrum. They are supplied uncoated but many types of anti-reflection coating may be applied on request. These achromats offer excellent performance for demanding laser and on-axis imaging aaplications.
