Product Description

General Introduction:
Biconvex lens is a kind of positive lens in the optical system mainly has the use of relay imaging (physical and real image) focusing divergent beams, convergent beams and other purposes. It is widely used in optical system applications such as beam expanding lenses, imaging lenses, and aggregation lenses.

Lens Substrates:
N-BK7

Optional I:	N-BK7 from CORNING, OHARA, SCHOTT, LEONI, AGC,HELLMA, NIKON,VITRON,ETC
Optional II:	Equivalent N-BK7 Made in China, C-laser own brands
