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.

N-BK7 manufactured ball lens. It is ideal for focusing light into optical fibers and for fiber coupling!
The TECHSPEC N-BK7 ball lens is a glass sphere commonly used in fiber optics applications. The ball lens is ideal for focusing light into fiber optics and for fiber coupling. - Suitable as a lens for fiber coupling and collimators - Perfect for preforms for aspheric lenses - Available in various sizes - Hemispherical lenses are also available *You can download the catalog from Edmund Optics Japan that features this product from the link 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.

TECHSPEC rod lenses are processed with a polished finish on the side surfaces and a sandblasted finish on the end surfaces. Their function is similar to that of cylindrical lenses. Parallel light passing through the center of the cylindrical section is focused into a line. We offer glass materials made of N-BK7 and synthetic quartz (UV grade) to accommodate various applications in UV, visible, and near-infrared ranges. A range of micro sizes is also available for implementation in many OEM applications. Custom sizes, changes to polished/sandblasted surfaces, and additional coatings can be accommodated upon request. ■ Focuses parallel light and converts it into a line ■ Available in sizes down to a minimum diameter of 1mm ■ Two types of glass materials: N-BK7 and synthetic quartz *You can download the catalog from Edmund Optics Japan 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.
