Achieving a φ0.35 glass molded aspheric lens.
Features of SUMITA's Precision Glass Mold Lenses: - Support for small lot production - Low cost - High precision - Support available from optical design - Prototype lenses available
Wide-ranging support for precision requirements, applications, and costs! Lighting lenses produced at low cost and in small quantities.
Our company manufactures "glass molded and aspheric lenses." To accommodate a wide range of precision requirements, applications, and costs, we offer production through polishing and glass molding methods according to your needs. We can produce from one polished lens to 100 glass molded lenses. Please feel free to contact us when you need our services. 【Materials (partial)】 ■ Polished spherical and aspheric lenses - CDGM K9/SCHOTT BK7: Nd=1.5163 - Corning Pyrex/Borosilicate: Nd=1.474 ■ Glass molded (heat press) spherical and aspheric lenses - CDGM HK51/SCHOTT B270: Nd=1.523 - Corning Pyrex/Borosilicate: Nd=1.474 *For more details, please refer to the related links or feel free to contact us.
Processing is possible with almost all types of glass materials, from hard glass to soft glass! We can keep unit costs down even for small production runs.
Kansai Special Optical Co., Ltd. processes aspherical lenses through grinding and polishing. We can process almost all types of glass materials, from high-melting-point hard glass like quartz to soft glass. Utilizing the technology developed for stage lighting, we can process mass-produced items up to 250mm in diameter and prototypes up to 300mm in diameter. Of course, we can also process small diameters of 10mm or less. 【Features】 ■ Processing is possible with almost all types of glass materials ■ Processing is possible from small diameters to large diameters ■ Low initial costs make it suitable for small-scale production *For more details, please refer to the PDF document or feel free to contact us.
Supports lens diameters from 15mm to 80mm, with countless K values, and up to high-order counts (A2Y2 to A20Y20).
Our company manufactures high-precision glass aspherical lenses using our own developed CNC glass lens grinding and polishing machines. Using the general aspherical formula (C×Y^2/(1+√(1-(1+K)×C^2×Y^2)), we can produce shapes that are extremely close to the design specifications. By comparing each piece with the design specifications using a contour shape measuring machine, we can demonstrate the high precision of our products. 【Manufacturing Range】 ■ Items with an outer diameter of 15mm to 80mm ■ Aspherical lenses with inflection points are difficult to manufacture, so please consult us ■ Freeform surfaces cannot be manufactured ■ Please inquire about concave aspherical glass lenses *For more details, please download the PDF or feel free to contact us.
Glass aspheric lenses produced at low cost and with short delivery times, starting from just one piece, through unique grinding and polishing processing.
Custom-made glass aspheric lenses manufactured to the specifications desired by the customer. ■ Unlike press manufacturing, there are no expensive aspheric mold costs, allowing for production with low initial costs. ■ Can be produced not only with general optical glass but also with quartz. ■ Produced using a unique grinding and polishing process that does not require expensive CNC aspheric processing machines, allowing for lower prices and shorter delivery times, starting from just one piece. *For more details, please refer to the related links or feel free to contact us.
We will introduce products that significantly contribute to the improvement and compactness of optical product performance.
At A.K. Corporation, we handle "aspheric lenses." Our products significantly contribute to the improvement of optical product performance and compactness. From glass to resin, we offer various shapes including cylindrical, toroidal, and other irregular lenses such as CPC and DOE (diffraction gratings), and we welcome your inquiries. Please feel free to contact us. 【Features of Each Processing Method】 ■ Cutting: Processing by directly applying cutting tools to the material ■ Grinding: Smooth finish achieved with super abrasive wheel processing ■ Mold forming: Significantly reduces processing time by using molds *For more details, please refer to the PDF materials or feel free to contact us.
