Custom K9 Glass Projection Lamp Laser Optical Spherical UV Lens

K9 glass is a high-quality raw material for producing various optical components. K9 glass lenses can be used in reflection, refraction, diffraction, transmission, and other ways to change the direction, intensity, phase, polarization, and other properties of light. K9 glass can also be used for producing window plates/discs, spherical lenses, non spherical lenses, cylindrical lenses, prisms, galvanometers, and filters. The diameter tolerance of K9 optical lens after precision annealing is+/-0.1mm, and the center thickness tolerance is ± 0.2mm. Due to its high transparency, K9 optical plates are commonly used in fields such as optical coating. Our company can customize various K9 glass optical components. Welcome to inquire.

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.
