Spherical Lens

Spherical Lens is available in spherical shape to focus beam as well as expansion. As the lens doesn't focus parallel rays to a common point, its "focus" depends on the distance from the centre of the lens. This phenomenon of "focus shift" helps focusing the image with the diaphragm that is wide open. It is widely used in different applications; hence it should be selected carefully. It should be chosen on the basis of f/number, conjugate ratio, lens material, transmission, etc. In addition, wave front distortion, types of coating and scattered light also keep in mind.

This precision lenses is developed from high-quality optical materials for high transmittance. It is designed with careful considerations to ensure to provide the fine shape to the lenses and shapes. It is available with high surface exactness and surface quality. It is used as shaving mirrors, reflectors in the headlights of vehicles, street light bulbs, search lights, etc.

Features of Spherical Lens:

1) High quality anti-reflection coatings are available.
2) Designed to suit a range of wavelengths from UV, visible, NIR, and MIR.
3) Available with positive focal length in best-form shape.
4) Damage proof design with fine cut and shape.
