GELINDE Optical Co., Ltd. 取り扱い製品

Optical Lens

Optical Lens

Our optical component products mainly consist of ball lenses and half-ball lenses, and we also provide cylindrical lenses, flat lenses, and windows based on our equipment capabilities. With extensive processing experience working with optical materials from prominent manufacturers and maintaining a diverse optical glass inventory, including CDGM, HOYA, SUMITA, NHG, SCHOTT, CORNING, NIKKON and more. We also excel in crafting specialized crystals like zinc selenide and cubic zirconia. Our ball lenses come in a wide range of diameters, boasting high roundness, tight diameter tolerances, and surface finishes up to 10/5, earning praise from our customers.

High Precision Balls

High Precision Balls

Our industrial high-precision products encompass a variety of non-metallic spherical componets, including high-precision glass spheres, high-precision gemstone spheres, and high-precision ceramic spheres. We source materials from top-tier suppliers, covering a range of materials such as soda-lime glass, borosilicate glass, technical glass, quartz glass, synthetic rubies, synthetic sapphires, alumina ceramics, zirconia ceramics, silicon nitride ceramics, and more. With proprietary equipment and processes, we have built a solid reputation for high consistency and low variance in mass production. Our expertise lies in machining high-precision spherical components conforming to ISO standards, achieving precision levels up to G3 depending on the material.

Preform Balls

Preform Balls

GELINDE Optical started Preform Ball processing in 2022, and has now built a monthly delivery capacity of 3 million molded ball preforms, serving several named China aspheric lens molding factories：
• Rapid Demond Response: closely and directly optical glass material suppliers' connection.
• High Cleanness: cleanliness control measures covering entire processing and packaging processes.
• High Consistency: specialized single-batch large-quantity, high-precision grinding processes, which effectively reduce batch variations by relatively decreasing the number of grinding batches.

Ruby Balls

Ruby Balls

Advantages of GELINDE Optical Ruby Balls
• High precision grades available: G10, G5, G3.
• Excellent batch consistency: For 2 mm ruby balls, we can produce 80,000 pieces per batch, with small dimensional deviation between batches.
• Surface roughness is customizable, with a minimum roughness of 5 nm.
• Customizable Ruby Blind Hole Balls
Product Features: Ideal for precision mechanical bearings, measuring instrument probes, pumps, valves, as well as high-temperature testing and heating equipment.
Product Applications: Precision mechanical bearings, measuring instrument probes, pumps, valves, high-temperature testing and heating equipment, etc.

Ceramic Balls

Ceramic Balls

Modern ceramics are also known as new ceramics, fine ceramics or special ceramics. They are commonly manufactured from non-silicate chemical materials or artificially synthesized raw materials, such as oxides (white: alumina, zirconia, titania, etc.) and non-oxides (black: silicon nitride, silicon carbide, etc.). Ceramics have many excellent properties, including insulation, corrosion resistance, high temperature resistance, high hardness, low density and radiation resistance, and have been widely used in various fields of the national economy.
GELINDE Optical can provide you with silicon nitride ceramic balls, silicon carbide ceramic balls, alumina ceramic balls and zirconia ceramic balls.
