In preference to the conventional but more difficult grind/polish method, Isuzu Glass uses a manufacturing process by which softened glass is pressed into a die. The advantages of the pressing method, compared to other mechanical processes, include the ability to make many lenses without losing quality, greater design flexibility, and lower cost. Isuzu Glass can also produce aspehric lenses with larger diameters. We use customer specifications (drawings and mathematical curvature formulas) to create molds and then manufacture lenses.

High-performance and high-functioning electronic and optical devices are being developed all the time. As a result, the optical components market demands various manufacturing techniques and advanced glass-molding methods. Therefore, the demand for such technology is expected to increase.
To satisfy such needs we succeeded in manufacturing a 50 mm aspheric lens with a P-V value of 30 microns. Our next target is 10 microns.

Using the heat-pressing method, we can achieve a surface accuracy and brightness similar to that of conventional ground/polished lenses. This method is best suited for the production of flanged lenses that are difficult to manufacture using conventional polishing methods.
We use customer specifications (drawings and mathematical curvature formulas) to create molds and then manufacture lenses. Depending on the application, we can offer a surface finish for scattering light, yellow coloring or tempering. We can also process the other side of the heat-pressed surface for a plano or radius finish.

Used to correct aberrations often caused by spherical lenses. Effectively works to align light beams from lamps with parallel beams. Used in various projectors, automobile headlamps, fog lamps, and other light sources.

Aspheric condenser lenses are used with light sources in microscopes and slide projectors. Heat absorbing filters are used for various lighting equipment to protect objects against heat rays from powerful light sources.
