Aspherical glass molded lenses improving the optical performance of precise equipment
With the technology to manufacture aspherical glass mold lenses, AGC is capable of producing lenses for diversified applications or in various shapes. Glass molding is a manufacturing method that enables high processing accuracy and mass-production, and it can also reduce the cost of manufacturing lenses in highly accurate shapes with less defects. AGC makes full use of its precision glass molding technology to manufacture and supply a variety of aspherical lenses that meet the needs of customers. Basically, AGC's products are customized to the specifications of each customer. We will be pleased to consider whether we can produce lenses other than those listed here. Please feel free to contact us.
For information on lenses that are molded by other methods, such as the reheat press method, see the product introduction page.
Glass Mold Lenses Specifications
Aspherical Glass Mold Lens
This type of aspherical glass lens is manufactured by making full use of our precision glass molding technology, and improves the performance of optical equipment. The lenses are used for digital cameras and automotive cameras. Being made of glass, they have excellent durability. In addition, the aspherical surface contour enhances image quality, helps reduce the number of lenses used, and has various other advantages.
| Applications |
・Digital cameras, monitoring cameras and automotive cameras ・Projectors ・Sensing devices |
|---|---|
| Lens shapes | Biconvex, meniscus (convex, concave), biconcave, toroidal, etc. |
| Lens types | Single lens, cemented lens (double-cemented, triple-cemented) |
| Size | φ 1 - 48.5 mm (please contact us for detailed specifications) |
| Special processing | I-cut, D-cut, Rectangular-cut, etc. (please contact us for detailed specifications) |
Square Aspherical Glass Mold Lens
This type of aspherical glass mold lens is square and manufactured by making full use of our precision glass molding technology. In addition to the high optical performance and reliable and stable quality of the glass which can be achieved with precision molding technology, these lenses are stable and can be easily aligned when mounted because they are not round shape. They are aspherical glass lenses having good mountability that can improve the performance of optical modules used in small spaces such as communications equipment.
| Applications | Optical communication modules, etc. |
|---|---|
| Lens shapes | Biconvex, plano-convex, etc. |
| Lens types | Single lens |
| Size | 0.6 - 1.5 mm × 0.6 - 1.5 mm (please contact us for detailed specifications) |
Cylindrical (Toroidal) Glass Mold Lens
This type of aspherical glass lens is manufactured by making full use of our precision glass molding technology, and it forms a variety of beam patterns.
Making full use of our precision glass molding technology, we at AGC manufacture and supply various shapes of aspherical lenses besides round ones to meet the needs of customers. Please feel free to contact us if you need special-shaped lenses.
| Applications |
・Projectors ・Sensing devices |
|---|---|
| Lens shapes | Biconvex, plano-convex, etc. (double-sided type is also available) |
| Lens types | Single lens |
| Size | 0.5 mm × 0.75 mm - 10 mm × 12 mm (please contact us for detailed specifications) |
Chalcogenide Aspherical Glass Mold Lens
This type of aspherical glass lens is made of chalcogenide glass, which has excellent infrared transparency, and is manufactured with our precision glass molding technology. As well as aspherical lenses for visible light, AGC can manufacture various shapes of high-precision chalcogenide glass aspherical lenses by using its metal molding technology that is highly suited to mass-production. They are manufactured in an integrated process from molding to film production, and maintain high reliability even when used in a high-temperature and high-humidity environment. We can also process lenses as follows. Please consult us.
- Producing lenses that take advantage of the high infrared transparency of glass materials
- Coating lens surface with advanced antireflection film
- Providing lens surface with diffraction grating function
| Applications |
・Monitoring cameras ・Night vision cameras ・Infrared analyzers |
|---|---|
| Lens shapes | Please consult us. |
| Lens types | Single lens |
| Size | φ 5 - 14.2 mm (please contact us for detailed specifications) |
Glass Molded Microlens Array
This is an optical element (lens array) made by precision glass molding on a glass substrate.
At AGC, we use optical glass materials and our precision glass molding technology to produce and supply microlens arrays which meet the needs of customers. By using glass, this lens array has higher light resistance and more stable thermal properties than lens arrays made of resin. We can also process lenses as follows. Please consult us.
- Forming submicron size lenses with high accuracy.
- Various lens layouts (array pitches) with high accuracy.
- Both single-sided and double-sided arrays
- Coating the surface with antireflection film.
| Applications |
・Digital cameras, light field cameras ・Projectors ・Other light diffusion control devices |
|---|---|
| Lens shapes | Please consult us. |
| Lens types | Single-sided array, double-sided array |
| Size | Max. 15 mm × 20 mm (please contact us for detailed specifications) |
