Double-Convex (DCX) Lenses, D=12.50mm, F=12.50mm, NIR H-K9L Optical Glass, United Optical Technology Co., Ltd (CAT#: STEM-OP-0683-YJL)

Double-Convex (DCX) Lenses, D=12.50mm, F=12.50mm, NIR H-K9L Optical Glass, model 110055, is manufactured by United Optical Technology Co., Ltd.
K9 Double Convex Lenses are double convex lenses based on K9 optical glass.
K9 optical glass is an excellent wide-spectrum transmission optical material with high transmittance in the 350nm-2000nm band and high hardness. It can withstand a variety of physical and chemical stimuli and has low bubble and impurity content, so it is often used as the base material for various optical components.

A lenticular lens focuses light into a point with a positive focal length and consists of two convex surfaces of equal radius. Commonly used in imaging relay systems and object imaging at limited conjugate distances. The characteristic is that the greater the conjugation ratio, the greater the aberration produced.
