Extreme ultraviolet (EUV) flat mirrors are Bragg reflection mirrors made of multilayer films with reflective coatings deposited on ultra-precision polished single crystal silicon substrates. The surface roughness is less than 3 Å. The mirror with a 45° incidence angle is designed for beam steering of s-polarized light, while the mirror with a 5° incidence angle is beneficial for use with unpolarized light. These mirrors can be used in applications such as coherent diffraction imaging (CDI), EUV spectroscopy, and nanomachining. 【Features】 ■ Achieves maximum reflectivity at 13.5 nm ■ Designed for extreme ultraviolet beam steering and harmonic separation ■ Available in 5° and 45° incidence angles

The MercuryTL liquid lens implementation telecentric lens merges the adaptability of telecentric lenses with the flexibility of liquid lenses.

Fresnel lenses are made of thin, flat acrylic resin with closely spaced, stepped, concentric grooves in a sawtooth pattern. Each groove acts as a small refractive surface (prism surface), allowing the entire lens to function as a single large 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 glass lenses, making them particularly useful for concentrating sunlight. They are also widely used as projection lenses for overhead projectors (OHP). 【Features】 ■ Negative focal length ■ Options for circular and rectangular shapes ■ Acrylic substrate *You can download the catalog from Edmund Optics Japan that features this product from the link below.

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.

■Ideal for use under harsh conditions ■High strength, high hardness ■Excellent chemical resistance ■Outstanding transmittance in the IR wavelength range ■Sapphire and ruby ball lenses also available *You can download the catalog from Edmund Optics Japan featuring this product below.

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.
