Ball Lenses, D=5.00mm, F=3.67mm, Uncoated H-K9L Optical Glass, United Optical Technology Co., Ltd (CAT#: STEM-OP-2651-YJL)

Ball Lenses, D=5.00mm, F=3.67mm, Uncoated H-K9L Optical Glass, model 160004, is manufactured by United Optical Technology Co., Ltd.
Ball lenses are primarily used in fiber optic applications because their short back focal length minimizes the distance required from the ball lens to the optical fiber. K9 optical glass is an optical material with excellent wide-spectrum transmission. It has high transmittance from 350nm to 2000nm, has high hardness, and can withstand a variety of physical and chemical stimuli. The content of bubbles and impurities is low, so it is often used as the substrate for various optical components.
