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 made by mold forming that can eliminate chromatic aberration caused by broadband light sources.
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.
Significantly improved water absorption and heat resistance! Plastic aspheric lens. Contributes to weight reduction and miniaturization.
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.

A precision glass aspheric lens that focuses divergent light while eliminating spherical aberration. It can also replace spherical lenses, reducing the total number of lens elements in the system!
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.
