Aspherical lenses that adopt a precision manufacturing process using the latest grinding and polishing equipment. They have an extremely low thermal expansion coefficient, making them suitable for use at high temperatures.
TECHSPEC synthetic quartz precision glass aspherical lenses are aspherical lenses manufactured using advanced grinding and polishing equipment in a precise manufacturing process. Optical design data is also available, making it possible to design and implement complex optical systems. Additionally, a low F-number design that excels in light gathering and point focus performance is adopted. To eliminate spherical aberration and minimize higher-order aberrations, the design is optimized through computer modeling. The use of synthetic quartz glass results in an extremely low thermal expansion coefficient, allowing for use at high temperatures (effective for powerful halogen lamps and metal halide lamps as well). ■ Low thermal expansion ■ Precision and high-accuracy options ■ High numerical aperture to maximize throughput *You can download the catalog from Edmund Optics Japan, which features this product, from the link below.
Adopting a plastic substrate that is lighter than glass aspheric lenses!
TECHSPEC plastic aspheric lenses are characterized by being lighter than glass spherical/aspheric lenses. They are available in a standard diameter of 25mm, making integration into systems easy. The substrate material used is cycloolefin polymer (COP) Zeonex E48R, which has low haze and low autofluorescence. The adhesion of the coatings is also excellent, making them ideal for OEM and research applications. ■ Aspheric coefficient data available ■ Standard size of 25mm diameter for easy system integration ■ High NA design with excellent light-gathering capability * You can download the catalog from Edmund Optics Japan that features this product from the link below.

Aspherical lenses are used in a range of applications, including barcode scanners, laser diode collimation, and integration for OEM and research and development, to eliminate spherical aberration. The use of aspherical lenses in single lens designs helps minimize the number of lenses in optical assemblies composed of multiple lenses. Unlike conventional lenses that adopt a spherical shape on the first surface, aspherical lenses feature a more complex surface shape where the curvature gradually changes from the center to the edge of the lens. Reducing the total number of lenses contributes not only to a decrease in the size and weight of the system but also simplifies the assembly process. By employing aspherical lenses in applications such as focusing the output from laser diodes, it is possible to reduce total costs and exceed the performance of assemblies designed with traditional spherical lenses. ■ For more details, please visit the official website of Edmund Optics via the link below.
