Laser line beam splitters are used to separate a laser beam with a specific wavelength. By varying the design of the dielectric coating, it is possible to achieve a wide range of power splitting ratios between the transmitted and reflected partial beam.

Optical telecommunication is usually conducted with infrared light in the wavelength ranges of 0.8–0.9 μm or 1.3–1.6 μm—wavelengths that are efficiently generated by light-emitting diodes or semiconductor lasers and that suffer least attenuation in glass fibers. Fiberscope inspection in endoscopy or industry is conducted in the visible wavelengths, one bundle of fibers being used to illuminate the examined area with light and another bundle serving as an elongated lens for transmitting the image to the human eye or a video camera.

The optical fibers used in fiber optics are sometimes made of plastic but most often are made of glass. A typical glass optical fiber has a diameter of 125 micrometers (μm) or 0.125 mm (0.005 inches). Plastic fibers are made of polymethylmethacrylate, polystyrene, or polycarbonate. These are cheaper to produce and more flexible than glass fibers, but their attenuation of light restricts their use to shorter links.

The basic medium of fiber optics is a hair-thin fiber that is sometimes made of plastic but most often of glass. A typical glass optical fiber has a diameter of 125 micrometres (μm), or 0.125 mm (0.005 inch). This is actually the diameter of the cladding, or outer reflecting layer. The core, or inner transmitting cylinder, may have a diameter as small as 10 μm. Through a process known as total internal reflection, light rays beamed into the fiber can propagate within the core for great distances with remarkably little attenuation, or reduction in intensity. The degree of attenuation over distance varies according to the wavelength of the light and to the composition of the fiber.

In telecommunications, optical fibers have been used to replace copper wire in long-distance telephone lines and for linking computers within local area networks. Fiber optics is also the basis of the fiberscopes used for endoscopy or inspecting the interiors of manufactured structural products.

Fiber optics, also spelled fibre optics, is the science of transmitting data, voice, and images by the passage of light through thin, transparent fibers.

When glass fibers of core/cladding design were introduced in the early 1950s, the presence of impurities restricted their employment to the short lengths sufficient for endoscopy. In 1966, electrical engineers Charles Kao and George Hockham, working in England, suggested using fibers for telecommunication, and within two decades silica glass fibers were being produced with sufficient purity that infrared light signals could travel through them for 100 km (60 miles) or more without having to be boosted by repeaters. In 2009 Kao was awarded the Nobel Prize in Physics for his work. Plastic fibers, usually made of polymethylmethacrylate, polystyrene, or polycarbonate, are cheaper to produce and more flexible than glass fibers, but their greater attenuation of light restricts their use to much shorter links within buildings or automobiles.

LASER COMPONENTS optimizes the beam splitters for a specific wavelength, a polarization, and an angle of incidence (AOI) typically of 45°. Naturally, other angles of incidence are also possible upon customer request.

Are you wondering which beam splitter is the right one for your application? We will be happy to advise you on your choice.

Fiber optics telecommunication uses infrared light in the wavelength ranges of 0.8–0.9 μm or 1.3–1.6 μm - wavelengths, efficiently generated by light-emitting diodes or semiconductor lasers and that suffer minimum attenuation in glass fibers.

Please note that the transmitted beam always undergoes an offset, the size of which depends on the thickness and refractive index of the substrate. You must also consider that dielectric beam splitters generally show a strongly wavelength-dependent degree of reflection.

When working with lasers, it is often necessary to split a laser beam into two or more defined partial beams. There are a variety of beam splitters for these applications, with different advantages and disadvantages. Dielectrically coated beam splitters have a high laser damage threshold.

A double convex lens/mirror is a converging lens. A double concave lens/mirror is also symmetrical across both its horizontal and vertical axis.
