Plano-Concave (PCV)Lenses, D=10.00mm, F=-100.00mm, NIR H-K9L Optical Glass, United Optical Technology Co., Ltd (CAT#: STEM-OP-0942-YJL)

Plano-Concave (PCV)Lenses, D=10.00mm, F=-100.00mm, NIR H-K9L Optical Glass, model 120138, is manufactured by United Optical Technology Co., Ltd.
K9 Plano Concave (PCV) Lenses are plano-concave lenses based on K9 optical glass.
K9 optical glass is an excellent wide-spectrum transmission optical material. It has high transmittance in the 350nm-2000nm band, 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 base material for various optical components.

Plano-concave lenses can radiate light and have a negative focal length. One side is flat and the other side is concave. They are often used for beam expansion, projection and enlarging the focal length of optical systems.
It has a negative focal length and negative spherical aberration, which can be used to offset the aberrations of other lenses in the system.
