Product Description

General introduction:Spherical lens is an important optical component, mainly made of optical glass and other materials, used for coupling between optical fibers, between lasers and optical fibers, and between optical fibers and detectors, or for thin-film filtering dense wavelength division multiplexing. The collimation of the fiber beam in the device.

Product Description:Spherical lenses are also called glass beads. It is a solid or hollow glass bead with a diameter of several micrometers to tens of micrometers, and its application fields involve various departments such as chemical industry, military industry, aerospace, transportation, petroleum, light industry, and medical treatment. It has the characteristics of good surface finish, good light reflectivity, directional reflectivity, high impact strength, chemical stability, and light bulk density.

There are two types of manufacturing methods for spherical lenses: one is to heat glass powder to a molten state through high temperature gas, and use surface tension to form round microbeads. There are powder method and calcination method; , the glass droplets form spherical beads due to surface tension. Glass beads have the characteristics of good surface finish, good light reflectivity, directional reflectivity, high impact strength, chemical stability, and light bulk density.

Spherical lenses are widely used and can be roughly divided into two categories:
1.Using the property of the reflected light energy of the spherical lens to be retroreflected in the direction of the incident light source, make traffic signs, add paint for road marking, or make reflection or photographic screens, etc.

2.Using its spherical shape, glass hardness, chemical stability and light bulk density, it is used as grinding media for metal workpieces, shot peening and cleaning treatment, and filling materials for plastic products. Hollow glass microspheres have the advantages of light weight, high strength and low thermal conductivity, and can be used as lightweight thermal insulation materials for aerospace technology, ship materials and chemical equipment.

Product material:
1) UV Fused Silica Ball Lenses (UV Fused Silica Ball Lenses) are used to improve the signal coupling between optical fibers, emitters and detectors, improve signal quality, and can also be used in endoscopy, barcode scanning, pre-processing of aspheric lenses materials, sensors, etc.

Ball lenses are primarily used in fiber optic applications because of their short back focal lengths, which minimize the distance required from the ball lens to the fiber. Ultraviolet fused silica glass material has a wider spectral range (185nm-2.1μm) than K9 optical glass, has excellent transmittance in the ultraviolet band, lower refractive index, better uniformity, and smaller thermal expansion coefficient , At the same time, it has higher chemical resistance and very low fluorescence, etc., and can be used to make various optical components.

2) K9 Ball Lenses are optical glass beads made of K9 material, which are used to improve the signal coupling between optical fibers, transmitters and detectors, and improve signal quality. They can also be used in endoscopy, barcode scanning, aspheric surface Lens preprocessing materials, sensors, etc.

Ball lenses are primarily used in fiber optic applications because of their short back focal lengths, which minimize the distance required from the ball lens to the fiber. K9 optical glass is an optical material with excellent wide-spectrum transmission. It has high transmittance at 350nm-2000nm, high hardness, and can withstand various physical and chemical stimuli. The content of bubbles and impurities is low, so Often used as a substrate for various optical components.
