Optical Corner Reflectors-manufacture,factory,supplier from China

Corner cube prisms are optics which act as corner reflectors. The basic operation principle is that there are internal reflections on three mutually orthogonal prism surfaces, producing a direction of a reflected beam which is nominally parallel to the direction of the incident beam – with the accuracy limited only by the accuracy of the surface orientation of the prism. Precision prisms can offer excellent parallelism of incoming and reflecting beams. It is usually specified as an angular deviation, e.g.

A corner cube (or cube corner), also known as a retroreflector, is an optical component with the unique ability to return an incoming beam of light directly towards its point of origin regardless of the beam's angle of entry. This property makes this prism type ideal for a wide variety of applications, such as laser resonator cavities, land surveying, ground based range-finding, satellite communications and space vehicle docking.Wisoptic offer a wide variety of retroreflectors at competitive prices and lead times, and are able to accommodate the most demanding requirements.

The Ceramic Laser Reflectors are high reflectance cavities used in solid state and CO2 laser systems. They are built either as a one-piece or two-piece system based on customer requirement.Ceramic cavities produce diffuse reflectance, which offers a very uniform beam profile. This diffuse reflectance also distributes light and consequently decreases hot spots in the pumped medium. These completely dense materials (e.g. Al2O3) exhibit higher strength and scratch resistance than traditional polymeric and thermoplastic materials.

Optical Lenses are designed to focus or diverge light and for imaging or alignment in an optical system. Optical Lenses, which may consist of a single or multiple elements, have a variety of applications. Lens forms can be divided into simple lenses (which include plano-convex lens, plano-concave lens, double-convex lens, double-concave lens, cylinder lens, drum lens, spherical lens in different shapes), achromatic lenses compound lens and multiple types.

Optical filters are used to selectively transmit or reject a wavelength or range of wavelengths. Their applications include fluorescence microscopy, spectroscopy, clinical chemistry, machine vision inspection, etc. Optical filters are widely used in light system of life science, imaging, industrial, or defense industries. For example, Bandpass interference filters are designed to transmit a portion of the spectrum, while rejecting all other wavelengths. Notch filters reject a portion of the spectrum, while transmitting all other wavelengths.

Optical Prisms are widely used to redirect light at a designated angle. They are ideal for ray deviation, or for adjusting the orientation of an image. An optical prism’s design determines how light interacts with it. When light enters an optical prism, it either reflects off an individual surface or several surfaces before exiting, or is refracted as it travels through the substrate.  WISOPTIC offers a wide range of optical prisms with various designs, substrates, or coatings.

Optical filter is usually a component with a wavelength-dependent transmittance or reflectance. It's used to selectively transmit or reject a wavelength or range of wavelengths.  Filters with particularly weak wavelength dependence of the transmittance are called neutral density filters. The general applications of optical filters include fluorescence microscopy, spectroscopy, clinical chemistry, machine vision inspection, etc. Bandpass interference filters are designed to transmit a portion of the spectrum, while rejecting all other wavelengths.

Polarization is an important characteristic of light. Polarizers are key optical elements for controlling your polarization, transmitting a desired polarization state while reflecting, absorbing or deviating the rest. There is a wide variety of polarizer designs, each with its own advantages and disadvantages.

There are four main types of prisms based on the function: dispersion prism, deflection or reflection prism, rotating prism and offset prism.  Deflection, offset and rotating prisms are commonly used in imaging applications; diffusion prisms are designed for dispersive light sources and are not suitable for any application that requires high quality images.WISOPTIC offers a wide range of optical prisms with various designs, substrates, or coatings.

When classified by coatings, Optical Mirrors consist of dielectric mirrors and metallic mirrors. Dielectric mirror is an optical mirror made of thin layers of dielectric coating layers deposited on an optical substrate (UVFS or BK7). WISOPTIC offer dielectric laser mirrors for laser lines, for narrowband or broadband wavelength ranges covering spectrum from UV to IR. Metallic mirrors are coated with protected gold, silver, or aluminum. Metallic mirrors are widely used due to a moderate level of reflection over a very broad spectral range.

Front surface mirrors are coated with aluminum or dielectrics for maximum reflection. WISOPTIC provides both kinds of front surface mirrors: metal coated mirror and dielectric coated mirror.Dielectric mirror is an optical mirror made of thin layers of dielectric coating layers deposited on an optical substrate (UVFS or BK7).  Dielectric laser mirrors are used for laser lines, for narrowband or broadband wavelength ranges covering spectrum from UV to IR. Metallic mirrors are coated with protected gold, silver, or aluminum.

Ceramic Laser Reflector (Ceramic Laser Cavity) works particularly well in Ruby, Nd:YAG, or Alexendrite laser pumping chambers and can be a highly cost effective alternative to metal coated reflectors. Compared to metal reflectors, ceramic units offer higher reflectivity and therefore enhanced laser power. Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk reflectivity.

Alumina Ceramic Reflectors are designed primarily for use in pumping chambers for many diverse laser systems, e.g. YAG lasers.

Optical beamsplitters play a vital role in many laser-based measurement and positioning systems. Although the operation of a typical beamsplitter is conceptually simple, its performance characteristics can dramatically affect the accuracy and repeatability of the overall system. Consequently, understanding the variables that distinguish beamsplitter performance is an important step in comparing and specifying components.

Compared to more commonly used KTP crystal, KTA crystal has larger non-linear optical and electro-optical coefficients. KTA has the added benefit of significantly reduced absorption in the 2 to 5 μm region.  It has found more and more applications in second harmonic generation (SHG), sum and difference frequency generation (SFG)/(DFG), optical parametric oscillation/ amplification (OPO/OPA), and electro-optical Q-switching. WISOPTIC do in-house growing and processing KTA crystal with high optical quality and various options of dimensional and coating specifications.

A wave plate, also called a phase retarder, is an optical device that changes the polarization state of light by generating an optical path difference (or phase difference) between two mutually orthogonal polarization components. When the incident light passes through wave plates with different types of parameter, the exit light is different, which may be linearly polarized light, elliptically polarized light, circularly polarized light, etc.

Optical lenses can be made in many shapes and may be comprised of a single element or form constituent parts of a multi-element compound lens system. They are used to focus light and images, produce magnification, correct optical aberrations and for projection, mainly controlling the focus or divergence light used in instrumentation, microscopy and laser applications.

Potassium dihydrogen phosphate KH2PO4 (KDP) is a transparent dielectric material best known for its nonlinear optical and electro-optical properties. Because of its nonlinear optical properties, it has been incorporated into various laser systems for harmonic generation and optoelectrical switching.

KTP (KTiOPO4 ) is one of the most commonly used nonlinear optical materials which offers a range of unique features: high optical quality, broad transparency range, wide acceptance angle, small walk-off angle, and type I and II non-critical phase-matching (NCPM) in a wide wavelength range.

Periodically poled lithium niobate (PPLN) crystal and MgO: PPLN are a new kind of nonlinear optical crystal, which can realize high-efficiency frequency conversion such as frequency doubling, sum frequency, and optical parametric oscillation in wave brand from visible to mid-infrared.  When doped with 5% MgO, the photodamage threshold and photorefractive threshold of PPLN are greatly increased (compared to that of pure PPLN), and their performance is more stable and suitable for room temperature use.

Waveplates (retardation plates or phase shifters) are made from optical materials  with precise thickness such as quartz, calcite or mica, which exhibit birefringence. The velocities of the extraordinary and ordinary rays through the birefringent materials vary inversely with their refractive indices. The difference in velocities gives rise to a phase difference when the two beams recombine.

The most notable benefit of aspheric lenses is their ability to correct for spherical aberration, an optical effect which causes incident light rays to focus at different points when forming an image, creating a blur. Spherical aberration is commonly seen in spherical lenses, such as plano-convex or double-convex lens shapes, but aspheric lenses focus light to a small point, creating comparatively no blur and improving image quality.

Thin film polarizers are based on interference within a dielectric optical thin-film coating on a thin glass substrate. They are made from composed materials which include a polarizing film, an inner protective film, a pressure-sensitive adhesive layer, and an outer protective film. Thin film polarizers are used for polarization separation, that's to say to change un-polarized beam into linear polarized beam.

Optical windows are made in the form of flat plates of a transparent medium that allow light into an instrument. Windows have high optical transmission with little distortion of the transmitted signal, but can not change the magnification of the system.
