K9 glass

K9 optical glass is a high-quality borosilicate glass widely used in the field of precision optics, K9 glass has high light transmittance (greater than92%) in the visible light to near-infrared band (400-2500nm), refractive index of about 1.516, Abbe number up to 64.2, thermal expansion coefficient as low as 5.5×10⁻⁶/°C, can maintain stable performance in a wide temperature range from -60°C to 400°C, Mohs hardness up to 6.5, excellent scratch and wear resistance. It is chemically inert, resistant to acid and alkali corrosion, and has an ultra-precision polished surface that achieves λ/10 (wavelength level) optical surface shape accuracy, ensuring low light loss and high imaging quality. It can effectively control dispersion and reduce aberrations in optical systems, especially suitable for manufacturing high-precision lenses, prisms, windows and optical splitting elements. It is widely used in high-end optical systems such as lasers, microscopes, astronomical telescopes, and industrial testing equipment.#optical #optics
