Generally, a Xenon lamp need to seal in a quartz glass tube of the two metal electrodes to store electrical energy, after a high vacuum tube filled with xenon gas treatment, to output the pulse light pulse discharge of the gas discharge lamp.
DIEN TECH provides high quality standard and custom-made narrow bandpass interference filters within the spectral range from 200 nm to 2300 nm.
DIEN TECH provides windows fabricated from a variety of substrate materials. Many of our windows are offered with or without AR coatings. Conductive windows, high vacuum conflats and windows, and Brewster windows, which eliminate p-polarization reflectanc
Plano-convex lens is the most common item used for light focusing and collimation.
Plano-concave lens is the most common item used for light projection and beam expansion. Coated with antireflective coatings, lenses are used in various optical systems, lasers and assemblies.
Biconvex lenses are used as magnifiers, objectives, condensing systems. Since both surfaces contribute to the power of biconvex lenses, they have shorter focal length than PCX lenses of equal diameter and surface radius.
The biconcave lenses are used in optical systems in combination with other lenses. These lenses also work as beam expanders, optical character readers, viewers and projection systems.
Positive Cylindrical Lenses are used to focus light to a thin line for effective harmonic generation in nonlinear crystals, in laser scanners, spectroscopy, dye lasers, acousto-optics or other applications.
Cylindrical lenses with negative focal length expand beam along one coordinate. Typical application for the lenses is beam shaping. Round laser beam can be focused into a line-spot with help of the lens.
Dove prisms are shaped from a truncated right-angle prism. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face.
The right angle prisms are often preferable to an inclined mirror in applications involving severe acoustic or inertial loads, because they are easier to mount, and deform much less than mirror in response to external mechanical stress.
These two prisms can expand or contract the beam in one direction without any changes in the other direction. By adjusting the angles among the incident beam and two prisms, the shape of the beam can be changed. It is very easy to turn elliptical beam int
Dispersing prisms have three 60° angles therefore they are also referred to as equilateral prisms. It provides advantage over diffraction gratings where higher orders diffraction effect is unwanted.
