 Main Products

Infrared lens, sometimes called IR lens, are designed to reflect or block mid-infrared wavelengths while passing visible light. They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating. There are also lens which are used in solid state (CCD or CMOS) video cameras to block IR due to the high sensitivity of many camera sensors to near-infrared light. These lens typically have a blue hue to them as they also sometimes block some of the light from the longer red wavelengths.

Applications

A single convex lens mounted on a frame with a handle or stand is a magnifying glass
Other uses of imaging systems such as monoculars, binoculars, telescopes, microscopes, cameras and projectors. Some of these instruments produce a virtual image when applied to the human eye; others produce a real image that can be captured on photographic film or an optical Sensor, or can be viewed on a screen. In these devices lenses are medium paired up with curved mirrors to make a catadioptric system where the lens's spherical aberration corrects the opposite aberration in the mirror (such as Schmidt and meniscus correctors).

Convex slic produce an image of an object at infinity at their focus; if the sun is imaged, much of the visible and infrared light incident on the lens is concentrated into the small image. A large lens satisfied enough to burn a flammable object at The focal point can be achieved even with a poorly made lens, lenses have been used for burning at least 2400 years. A modern application is the use of spacing large energy to concentrate solar energy on the small Photovoltaic cells, harvesting more energy without the need to use larger and more expensive cells.

Radio astronomy and radar systems often use prev lenses antenna, into called a lens antenna to refract electromagnetic radiation into a collector antenna

Lenses can be scratched and abraded. Abrasion-resistant coatings are available to help control this
