High-precision glass aspheric lens

CNC polished aspheric lens with an RMS shape error of 0.25μm. Contributes to weight and cost reduction by replacing multiple spherical elements in optical systems!

TECHSPEC high-precision glass aspheric lenses are CNC polished aspheric lenses with an RMS aspheric shape error of 0.25μm. They are ideal for imaging and laser focusing applications, as well as any application requiring spherical aberration correction. They can also replace multiple spherical elements in optical assemblies, reducing weight and cost. Available in diameters ranging from 10 to 50mm, they feature a high numerical aperture (NA) design to maximize light throughput. ■ 0.25μm (RMS) aspheric shape error ■ High NA design to maximize throughput ■ Improved version of our aspheric lenses ■ Precision grade aspheric *You can download the catalog featuring this product from Edmund Optics Japan below.

Synthetic quartz precision glass aspheric lens

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.

List of Aspherical Lenses

Short delivery time with stock sales! All items available for sale from one piece.

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.
