A diffraction grating uses a substrate with parallel grooves to disperse light into its spectra. Eschelles are included in this area.
|
|
Halogen lamps are high pressure incandescent lamps containing halogen gases such as iodine or bromine, which allow the filaments to be operated at higher temperatures and higher efficacies.
|
|
Lamps are light sources that emit incoherent light for illumination. There are many different types of products. Examples include fluorescent lamps, halogen lamps, heat lamps, incandescent lamps, LED lamps, projection lamps, spectral lamps, and stage lamps. Specialized and proprietary lamps are also available.
|
|
Monochromators are optical subassemblies used to isolate narrow portions of a light spectrum. They accept polychromatic input from a lamp or laser, and outputs monochromatic light.
|
|
Neutral density filters are designed to reduce transmission evenly across a portion of the spectrum. They are slightly sensitive to angles but they are much more forgiving than interference filters.
|
|
Nonpolarizing cube beamsplitters provide a true 50/50 split regardless of the incoming polarization. They consist of a pair of precision right-angle prisms carefully cemented or mounted together to minimize wavefront distortion.
|
|
Optical bandpass filters are designed to transmit a specific waveband. They are composed of many thin layers of dielectric materials, which have differing refractive indices to produce constructive and destructive interference in the transmitted light.
|
|
Optical flats or test plates are polished surfaces that are used as references against the flatness of unknown surfaces for comparison. They use the property of interference to measure the flatness of a test surface.
|
|
Optical lenses are transparent components made from optical-quality materials and curved to converge or diverge transmitted rays from an object. These rays then form a real or virtual image of the object. This area includes micro lenses.
|
|
Optical mirrors have a smooth, highly-polished, plane or curved surface for reflecting light. Usually, the reflecting surface is a thin coating of silver, or aluminum on glass.
|
|
Optical polarizers are optical devices that can transform unpolarized or natural light into polarized light, usually by the selective transmission of polarized rays.
|
|
Optical prisms are blocks of optical material with flat, polished sides that are arranged at precisely controlled angles to one another. They are used in optical systems to deflect or redirect beams of light. They can invert or rotate images, disperse light into component wavelengths, and separate states of polarization.
|
|
Optical windows are used to isolate different physical environments while allowing light to pass relatively unimpeded.
|
|
Polka dot beamsplitters consists of an ultraviolet grade fused silica substrate with a vacuum deposited aluminum coating applied in a manner that gives the beamsplitter a polka dot appearance. They have a constant 50/50 reflection-to-transmission ratio over a large spectral range.
|
|
Spectral lamps radiate line spectra of various gases and metal vapors with high brightness and spectral purity.
|
Spectrometers are analytical instruments which disperse an emission (such as particles or radiation) according to some property of the emission (such as mass or energy) in order to measure the amount of the dispersion. This product area includes Portable / Miniature, visible, infrared (IR), ultraviolet (UV), atomic absorption (AA), optical emission (OE), Raman, X-ray fluorescence (XRF) and mass spectrometers. Specific search forms are also available.
|
|
Spherical lenses, also known as singlets, are transparent optical components consisting of one or more pieces of optical glass with surfaces so curved that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object. This area includes micro spherical lenses as well.
|
|
Spherical mirrors are curved so that reflected beams converge on a focal point.
|
|
UV and visible spectrometers measure the amount of ultraviolet (UV) and visible light transmitted or absorbed by a sample placed in the spectrometer.
