K9 Lens
K9 glass, also known as K9 optical glass, is a widely used general-purpose optical material. It is a silicate glass composed mainly of SiO₂, B₂O₃, Na₂O, and other constituents. K9 lenses made from this substrate offer high cost effectiveness and excellent machinability, making them a mainstream choice for optical systems from the low-to-middle end through the middle tier. The core advantages of K9 lenses are cost effectiveness, easy processing, and fulfillment of basic visible-light requirements. They are an economical, practical choice for conventional visible-light optical systems and are widely used in consumer electronics, industrial imaging, and other fields with moderate performance requirements.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
