Product Description

General Introduction:
A lens is made by grinding a transparent material such as glass into a round sheet so that both surfaces are curved or one surface is flat. Its function is to cause light beams to converge or diverge through the refraction of its two surfaces, and to form an image of the object at any desired location. 
A Doublet lens is made by gluing two lenses together. This combination lens is an effective method to obtain short focal length, high magnification and good image quality. It has been widely used in astronomical telescopes and cameras.
