When considering the lightweight, compact design, or mass production and workability of lenses, acrylic (PMMA) and polycarbonate (PC), which are thermoplastic resin materials, are regarded as superior lens materials compared to optical glass. However, it has been a concern that when such resins are used in harsh environments like high temperatures and high humidity, the changes in optical properties tend to be greater than those of optical glass. Therefore, it is true that there have been limitations on their use as lenses. This plastic aspherical lens is made from a polyolefin-based thermoplastic resin that has light transmittance and low birefringence comparable to PMMA, while significantly improving PMMA's drawbacks of water absorption and heat resistance. In fact, this material has been successfully introduced in pickup lenses for car CD players that require heat resistance up to 120°C. By adopting an aspherical design, the effective diameter of the lens can be fully utilized, resulting in high-quality and powerful images. ■ Excellent durability in harsh environments ■ High heat resistance ■ Low water absorption *The catalog of Edmund Optics Japan can be downloaded from the link below.

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.

The TECHSPEC plastic hybrid aspheric lens is a molded aspheric lens designed with a diffraction-limited design that eliminates chromatic aberration caused by broadband light sources. It is ideal for imaging and ophthalmic applications, as well as for use with tunable lasers and broadband/multi-wavelength light sources. While the aspheric shape removes spherical aberration, the diffraction optical surface applied to the same plane provides negative optical dispersion, resulting in exceptional chromatic aberration correction. ■ Color-corrected plastic aspheric lens ■ Minimizes the occurrence of chromatic aberration through the diffraction optical surface ■ Low-cost molded design *You can download the catalog from Edmund Optics Japan that features this product from the link below.

■Partial correction of TECHSPEC plano-convex lenses ■Performance optimized for the design wavelength ■Diffraction-limited spot size *You can download the catalog from Edmund Optics Japan featuring this product below.*

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.

TECHSPEC precision glass aspheric lenses are designed to focus divergent light sources, such as the output from laser diodes, while eliminating spherical aberration. They allow for an increase in the lens's numerical aperture (NA) while minimizing system aberrations. By using aspheric lenses instead of spherical lenses, it is also possible to reduce the number of lenses required throughout the system. These lenses enable an increase in throughput and simplification of assembly while reducing the overall weight of the system. ■ Designed and manufactured by Edmund Optics ■ Reduces spherical aberration ■ Diameters from 10 to 200 mm ■ Focal lengths from 7.5 to 300 mm ■ Wideband anti-reflective (AR) coatings are also available *You can download the catalog featuring this product from Edmund Optics Japan below.

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.
