Spherical Lenses

Spherical lenses are used to focus, form images, and to collimate or expand light.  They are used in almost every optical system, from high power, deep-UV lasers to low-cost condensers delivering light to a detector.  CVI Laser Optics has solutions for them all.  Our vast selection of lens shapes, materials and lens quality options will allow you to find the right balance between performance and cost for even the most demanding application.

Aside from shape, material type and manufacturing quality are the most important factors that determine lens performance.

Picture for category Plano-Convex Spherical Lenses

Used for converging or focusing of light, as well as for collimating point sources.  Cost-effective alternative to a positive best-form lens when used at infinite conjugate ratio, with collimated light incident upon the convex side.   Reduced spherical aberration and near-zero coma when used off-axis.  

Picture for category Bi-Convex Spherical Lenses

Used for 1:1 imaging, beam expanders, and beam relay applications.  Good positive lens for virtual imaging of real objects and for positive conjugate image ratios from approximately 0.2 to 5 (depending on wavelength).  Can also be used for focusing applications at lower f-number.  It performs like a bestform singlet lens when used at unit conjugate ratio.  

Picture for category Positive Bestform Lenses

Used for converging or focusing of light, as well as for collimating point sources. Designed and manufactured to minimize coma and spherical aberrations in focusing applications, positive bestform lenses are of exceptional performance and provide the smallest spot size available in a singlet lens. 

Picture for category Plano-Concave Spherical Lenses

Used to expand light or to increase focal lengths in optical systems, or to balance aberrations from other lenses within a system.  Negative focal length diverges collimated incident light.  Spherical aberration, and coma are reduced when used at infinite conjugate ratio with collimated light incident upon the concave side.   

Picture for category Bi-Concave Spherical Lenses

Used to diverge or expand light in laser beam expanders, optical character readers, viewers, and projection systems.  Negative focal length; forms a virtual image which can be seen through a lens.  

Picture for category Aspheric Glass Condenser Lenses

Used for light collection applications requiring a low cost, positive lens.  Reduced aberrations for low f-number, high-throughput use.  Not recommended for imaging, precise focusing, or high power applications.
