Ophthalmic Lenses

we manufacture and supply meniscus (positive) lens that is shell-shaped, and has one convex and one concave surface. These lenses have a steeper convex surface and are thicker at the center than at the periphery. Designed in order to minimize spherical aberration, these lenses have a huge demand in the global market. When used in combination with another lens, a positive meniscus lens will shorten the focal length, and increase the na of the system. Further, these lenses are used to decrease the focal length of another lens, and maintain the angular resolution of the optical assembly.

Negative Cylindrical Lens offered by us act similar to the Plano-concave spherical lenses. The only difference is that these Lenses expand light in one dimension only. These Lenses are ideal for application in areas where one dimensional shaping of a light source is required. Typically, a Cylindrical Lens is used to turn a collimated laser beam into a line generator. A pair of these Lenses can be used to anamorphically shape images. These Lenses are used in laser scanners, spectroscopy, dye lasers, acousto-optics, optical processors or other applications.

We are offering our clients Positive Cylindrical Lens that has surfaces with two different radii of curvature in two orthogonal planes. Such Lenses are used for magnifying in one dimension, and for focusing a diverging beam on to a detector array. Unlike spherical lenses that act symmetrically in two dimensions, Cylindrical Lens act in the same manner but only in one dimension. Positive Cylindrical Lens can be used in pair for providing anamorphic shaping of a beam. The pair of these Lenses can also collimate and circularize the output of a laser diode.

We bring forth for our clients high quality Bi-Concave Lens that is manufactured with both surfaces concave. These lenses have negative focal length, and are appropriate for diverging collimated incident light. The lenses form virtual images that can be seen through the lens. Often, these lenses are used to expand light, or increase focal lengths in existing systems. Bi-concave lenses are best suited for places where the input beam is converging, as in laser beam expanders, optical character readers, viewers, and projection systems.

Plano-Concave Lens is a negative (diverging) spherical lens with one concave surface and one flat (plane) surface. We manufacture and supply these Lenses for diverging the collimated incident light, as in a Galilean type beam expander or telescope. These Lenses form virtual images, which are seen through the lens. Often, these Lenses are used to expand light or to increase focal lengths in existing systems. A unique characteristic of this lens is that it can balance the aberration caused due to the other lenses. This property is due to the negative spherical aberration of the Plano-Concave Lens.
