Laser Research Optics has introduced precision optics custom fabricated from ZnSe, ZnS, fused silica, germanium, silicon, ...

A plano concave lens is an optical lens with one concave surface and one flat surface. It has a negative focal length, and can be used for light projection, beam expansion, or to increase focal length ...

Plano convex lenses, Plano concave lenses, Bi-convex lenses, Bi-concave lenses, meniscus lenses, achromatics lenses, ball lenses, aspheral lenses and cylindrical lenses Specifications: Material: Bk7, ...

Refraction is the change in direction of light when it passes from one medium to another. The working of a lens is based on the refraction of light when they pass through it. Lens is a transparent ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...

Researchers have harnessed nonlocal artificial materials to create optical systems that emulate parallel spaces, wormholes, ...

Astronomy. What’s the first thing you think of when you read that word? The many beautiful vistas returned from Hubble? A family in a backyard huddled around a small telescope? Giant research ...

Mirror is a reflecting surface or a polished metal that forms images. It works on the principle of reflection of light. When a man stands in front of the mirror, light from all parts of the body is ...

The optical lens, as an indispensable tool, has been widely exploited in various scientific communities, and its operation is well understood on the basis of classical optics. Traditionally, reshaping ...

Draw a ray from the object to the lens that is parallel to the principal axis. Once through the lens, the ray should pass through the principal focus. Draw a ray which passes from the object through ...
