Penta Prisms-manufacture,factory,supplier from China

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.

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.

Right angle prisms are generally used to bend image paths or redirect light at 90°. This produces a left handed image and depending on the orientation of the prism, the image may be inverted or reverted.

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.

Polarizing Beamsplitters (PBS) splits incident unpolarized light into two perpendicular linearly polarized light. Among them, p-polarized light passes through completely, while s-polarized light is reflected at 45 deg which makes the emitting direction of s-light vertical to p-light. Additionally, beamsplitters can be used in reverse to combine two different beams into a single one. Beamsplitters are often classified according to their construction:cube or plate.Cube PBS are fabricated using two typically right angle prisms.

A prism, in optics, is a piece of glass or other transparent object surrounded by two planes that intersect but are not parallel to each other. The most important parameters of a prism are the angle and material.  Prisms are capable to redirect light at a designated angle or adjust the orientation of an image. Therefore prism is useful for in certain spectroscopes, instruments for analyzing light and for determining the identity and structure of materials that emit or absorb light. An optical prism’s design determines how light interacts with it.

Polarization optics is important for both intra and extra cavity use. By using high contrast thin film polarizers in their design, laser engineers can save weight and volume within the laser system without influencing the output. Compared with polarizing prisms, polarizers have larger incident angle and can be made with larger apertures. Compared with polarizers made from birefringent crystals, the advantage of thin film polarizers made from UVFS or N-BK7 is that they can be fabricated in very large sizes, therefore are particularly well suited for high laser powers and UV wavelengths.

Phase retardation plates, or waveplates, are polarizing optics used to manipulate the polarization state of the transmitting light without attenuating, deviating, or displacing the light. The working principle of the plate is to utilize the birefringence of certain materials which separates the incident light beam into two beams along two orthogonal optical axes within the medium. The phase retardation between the two beams of the incident light contributes to changes in the polarization state.

Lithium Niobate (LiNbO3) is widely used  in fiber communication devices as birefringent crystal and used as electro-optic modulator and Q-switch for Nd:YAG, Nd:YLF and Ti:Sapphire lasers. It has good mechanical and physical properties and is ideal for optical polarizing components due to its wide transparency range and low cost. LiNbO3's applications for fiber communication include isolators, circulators, beam displacers, and other polarizing optics. The transverse modulation is mostly employed for LiNbO3 crystal.

Thin Film Polarizers are made from composed materials which include a polarizing film, an inner protective film, a pressure-sensitive adhesive layer, and an outer protective film. Polarizer is used to change un-polarized beam into linear polarized beam.

Polarizer is a kind of optical filter where the light transmission depends strongly on the polarization state. Normally, light with linear polarization in a certain direction is passed, and light polarized in an orthogonal direction is either absorbed or propagated to a different direction.For other directions of linear polarization with an angle θ against the“passing”direction, the transmission exhibits a cos2 θ dependence. That can be understood by considering that linear polarization state as a linear superposition of the "passing”and the“blocked”state.Most polarizers act

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.

When choosing a window, the user should consider whether the material's transmission properties and the mechanical properties of the substrate are consistent with specific requirements of the application. Coating is another important issue for choosing a proper window. WISOPTIC offer a wide variety optical windows with different coatings, e.g. anti-reflection coated precision windows for Nd:YAG laser applications.

Wisoptic' standard and precision quality laser windows are fabricated from a variety of substrate materials, e.g.  UVFS and N-BK7. They are available either with or without AR coatings, and with dia from 12.5 to 101.6 mm and thickness from 1 to 15 mm. Also we offer uncoated rectangular windows with aperture from 15 x 20 to 50.8 x 50.8 mm and thickness from 2 to 10 mm.

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 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.

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.

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.

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.

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.

Wisoptic’s optical mirrors are available for use with light in the UV, VIS, and IR spectral regions. Optical mirrors with a metallic coating have high reflectivity over the widest spectral region, whereas mirrors with a broadband dielectric coating have a narrower spectral range of operation; the average reflectivity throughout the specified region is greater than 99%.
