Plano-Convex Lenses, D=12.00mm, F=20.30mm, SWIR H-K9L Optical Glass, United Optical Technology Co., Ltd (CAT#: STEM-OP-0127-YJL)

Plano-Convex Lenses, D=12.00mm, F=20.30mm, SWIR H-K9L Optical Glass, model 100281, is manufactured by United Optical Technology Co., Ltd.
K9 Plano Convex (PCX) Lenses are plano-convex lenses based on K9 optical glass material.
K9 optical glass is an optical material with excellent wide-spectrum transmission. It has high transmittance for light with a wavelength of 350nm-2000nm. It also 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. The K9 plano-convex lens focuses light into a point.

The focal length is positive, one side is flat and the other side is convex. Often used for aiming and focusing monochromatic light sources. When in use, face the convex surface towards the incident light. The K9 plano-convex lens combined with other lenses can be used for different applications such as beam shaping, beam collimation, beam expansion, beam contraction, etc.
