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.

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.

Aspherical cylindrical lenses (cylindrical lenses) focus light in only one direction, achieving a sharp and narrow line profile.
TECHSPEC aspheric cylindrical lenses (cylindrical lenses) focus light in one direction only, achieving diffraction-limited concentration similar to aspheric lenses. They are ideal for forming a fine line profile by reducing spherical aberration along the focusing axis. Additionally, compared to standard cylindrical lenses, they dramatically reduce the spot size of monochromatic light sources, creating sharp and fine lines. ■ Diffraction-limited design ■ Optimal for forming fine line profiles using monochromatic light sources ■ Focus light in one direction only *You can download the 'Optical Components & Optical Instruments Comprehensive Catalog <Sample Version>' from Edmund Optics Japan below.

Synthetic quartz with high transmittance from ultraviolet (UV) to infrared (IR)! Ball lenses and hemispherical lenses.
Synthetic quartz glass has high transmittance in the wavelength range of 200 nm to 2.2 μm and low thermal expansion characteristics. Ball lenses made from this glass are ideal for applications that require stringent demands using ultraviolet, visible, and near-infrared spectra. Additionally, the hemispherical lens, which is half the shape of a ball lens, has the advantage of being easier to join to fiber optic end faces than a ball lens. It is optimal for fiber optic communication, endoscopes, and high NA objective lens SIL (Solid Immersion Lens), among others. ■ Excellent UV transmittance ■ Low thermal expansion coefficient ■ High precision design *You can download the catalog from Edmund Optics Japan that features this product from the link below.

Scratch-resistant and ideal for use under harsh conditions! Sapphire and ruby ball lenses.
Sapphire and ruby, made of hard materials, are resistant to scratches and are ideal for use under harsh conditions. Both are composed of alumina (Al2O3), and the red color of ruby is due to trace amounts of chromium oxide (generally over 0.5% by content). Unlike common optical glass, which has an upper transmission wavelength limit of about 2.3μm, they are transparent up to about 5.5μm. Sapphire and ruby have fundamentally the same physical and chemical properties, but there are slight differences in their optical characteristics. Sapphire is colorless and transparent with high light transmission, while ruby is colored, making it highly visible and easy to handle, which is why it is preferred for mechanical applications. ■ Ideal for use under harsh conditions ■ High strength and hardness ■ Excellent chemical resistance ■ Superior transmission in the IR wavelength range ■ Sapphire & ruby hemispherical lenses are also available *You can download the catalog from Edmund Optics Japan, which features this product, from the link below.
While it has the same function as a ball lens, the drum lens is easy to handle! It is also easy to fix to a gold frame.
While the ball lens has a surface that is entirely polished, the drum lens has a sanded surface on all sides except for the entrance and exit faces, which are processed parallel to the optical axis. This makes handling easier compared to the ball lens, and it also facilitates attachment to a metal frame. Additionally, it contributes to miniaturization and weight reduction. The half drum lens is a special drum lens that has one side polished to a flat surface. The flat processing provides the advantage of easy bonding to the end face of optical fibers. As a lens, it functions like a thick plano-convex lens, and when parallel light is incident, it images at a lower NA (suitable for SM fibers). Both designs of the drum lens can be made from two types of glass: standard optical glass N-BK7 and high refractive index glass N-LaSF9. *Please note that lenses made of N-LaSF9 are available only while existing stock lasts. Thank you for your understanding. *You can download the catalog from Edmund Optics Japan from the link below.

For light gathering purposes, for enlarged projection with overhead projectors (OHP), and for condenser applications! Please take a look at our lineup of Fresnel lenses.
A Fresnel lens is a thin, flat acrylic resin that has been densely engraved with sawtooth grooves in a stepped and concentric circular pattern. Each groove functions as a small refractive surface (prism surface), allowing the entire lens to perform the same function as a large single lens. Some types of Fresnel lenses are also used as magnifying glasses, but they tend to cause more stress on the eyes compared to spherical lenses. For the same focal length, the light transmission rate of a thin Fresnel lens is usually higher than that of a glass lens, making it particularly useful for concentrating sunlight. It is also widely used as a projection lens for overhead projectors (OHP). 【Features】 ■ Positive focal length ■ Options for circular and rectangular shapes ■ Ideal for concentrating applications *You can download the catalog from Edmund Optics Japan that features this product from the link below.
