Plano-Convex Lenses
This kind of lenses has positive focal lengths. They work best when producing real images at infinite conjugates when the convex surface is facing to the object .

Plano-Concave Lenses

Their popular applications are to increase focal lengths in existing systems. They are a moresuitable choice than the equivalent equi-concave lens if the magnification lies in the range of <-5 to>0.2.

3.jpgEqui-Convex Lenses
These lenses have different or equal radius of curvature on both sides with large range of focal lengths. The lens with equal radius of curvature is the optimum shape for producing real images at 1:1 magnification.
 
4.jpgEqui-Concave Lenses
This kind of lens with different or equal radius of curvature on both surfaces, diverges collimated incident light, and forms only virtual images that are seen through the lens. It is often used to expand light beams or to increase focal length in existing systems. 
5.gifMeniscus Lenses
Meniscus lenses are employed to the greatest advantage to shorten the focal length of a doublet or a plano-convexlens already working at an infinite conjugate.
6.gifBall Lenses
Ball lenses in various sizes made of optical glass are produced to provide a high coupling efficiency when used  with fiber optics. They are simple to use as they can be  put in contact with the end of the fiber. 
7.gifCone Lenses
These components are designed for use in a variety of laser  and imaging applications with standard sizes from 3mm to10mm. Other specifications are available on request. There are coated and uncoated versions provided to meet different  applications for the customer. Cone Lenses can be used for 360 degree illumination and imaging applications.Top and  base of the lens are polished while circumference is ground. 
8.gifRod Lenses
These components are designed for use in a variety of laser and imaging applications with standard sizes from 2mm to 10mm. Other specifications are available on request. Rod Lenses are polished on the circumference and ground onboth ends. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod will be focused into a straight line.
9.jpgAchromatic Lenses
Achromatic Doublets-These lenses are made of two different glasses, crown and flint. They are designed to perform well throughout the entire visible spectrum with spherical and chromatic aberrations corrected to the required specificationeven to the diffraction limits. Their ability of producing sharper images is superior to that of the single element lenses. Triplet Achromats-Triplets specifically designed for 1:1  conjugate ratios are ideal for use in relay systems. By theprinciple of symmetry aberrations are corrected automatically.
