K9 Highly Transparent Optical Glass Hemispherical Lens Spherical Lens

K9 glass is a highly transparent optical glass material. It can be used to customize various shaped optical components. K9 hemispherical lens is one of the common optical components. K9 spherical lens is an important optical component, mainly made of K9 optical glass and other materials, used for coupling between optical fibers, lasers and optical fibers, and between optical fibers and detectors, or for collimating fiber beams in thin film filtering dense wavelength division multiplexers. The application fields involve various departments such as chemical industry, military industry, aerospace, transportation, petroleum, light industry, and medical care.

Main characteristics

1. With excellent optical properties, K9 glass is widely used in optical coating and other fields.Its optical constants refers to refractive index =1.51630, dispersion =0.00806, abbe number =64.06.
2. The density of K9 glass is 2.5 ~ 2.6g/cm³, and the weight is moderate. The hardness is 5.5 Mohs, resistant to a certain degree of scratch and wear.These physical properties make it suitable for a wide range of processes, such as cutting, edging, special-shaping, drilling, coating, tempering, frosting, polishing, etc..
3. The melting point is about 700℃, and it has good stability in normal use environments.
