Dielectric, Dichroic & Metallic Mirrors-manufacture,factory,supplier from China

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%.

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.

A right angle prism is an optical prism designed to deviate light by 90° or 180°, depending on the orientation of the prism and the face through which light enters. The joining edges and faces are perpendicular to the base faces, and all joining faces are rectangular. They are often  preferable to plane mirrors, because they are easier to mount and align.

Bandpass Filters are used in a variety of industries, including machine vision,factory automation, security and surveillance, license plate recognition, medical and life science, agricultural inspection, aerial imaging, motion analysis, photography and cinematography.WISOPTIC's bandpass filters include mass collection of  dielectric-coated filters, colored glass filters, neutral density filters, spatial filters, and tunable optical filter based on liquid crystal technology. Specifically speaking, e.g.

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.

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.

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.

LN Crystal is a multifunctional material that integrates properties of piezoelectric, ferroelectric, pyroelectric, nonlinear, electro-optical, photoelastic, etc. LiNbO3 has good thermal stability and chemical stability.As one of the most thoroughly characterized nonlinear optical materials, LiNbO3 is suitable for a variety of frequency conversion applications. For example, it is widely used as frequency doublers for wavelength >1 μm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices.

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.

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.

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 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.

Compared with congruent LN (cLN) crysal, the electro-optic coefficient, nonlinear optical coefficient, periodic polarization reversal voltage and applied photorefractive properties of stoichiometric LN (sLN) crystal are greatly improved. With such excellent physical properties and wide application prospects, sLN crystal has rapidly become a competitive optoelectronic material.sLN crystals are expected to be thermodynamically stable up to their melting temperature at 1170°C, while keeping a largerelectrical resistivity than cLN crystals by one order of magnitude at any temperature.

Pure LiNbO3 (LN) is a good candidate for various optical devices, but has a major disadvantage due to its low threshold optical damage. MgO:LN (congruent compositions) is one of the possible solutions to deal with this problem. MgO doping has played an important role in LN and shown an increased threshold laser beam strength by 100 times. An interesting point is that every physical property of MgO:LN (e.g.

Nd:YVO4 (Neodymium-doped Yttrium Vanadate) is one of the best commercially available material for diode-pumped solid-state lasers, especially for lasers with low or middle power density. For example, Nd:YVO4 is a better choice than Nd:YAG for generating low-power beams in hand-held pointers or other compact lasers. In these applications, Nd:YOV4 has some advantages over Nd:YAG, e.g.

Yb:YAG (Ytterbium-doped Yttrium Aluminum Garnet) is one of the most promising laser-active materials with a large absorption bandwidth and typical emission at 1030 nm. Yb:YAG is more suitable for high power diode-pumped lasers than the traditional Nd-doped systems. The broad absorption band enables Yb:YAG to maintain uninterrupted pump efficiency across the typical thermal shift of diode output.

SHG of Nd:Laser - KTP is the most commonly used material for frequency doubling of Nd:YAG and other Nd-doped lasers, particularly when the power density is at a low or medium level.

One of the most important drawbacks of popular LiNbO3 crystal is its susceptibility to photorefractive damage (optically induced change of refractive index, usually under exposure with blue or green CW light). The usual way to eliminate this effect is to keep LN crystals at elevated temperatures (400K or more). Another way to prevent photorefractive damage is MgO-doping (usually at levels of around 5 mol% for congruent LN).

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 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.

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

Polarizing Beamsplitters (PBS) are designed to split light by polarization state rather than by wavelength or intensity. PBS are often used in semiconductor or photonics instrumentation to transmit p-polarized light while reflecting s-polarized light. Optical isolators use PBS to eliminate feedback-induced damage. PBS are typically designed for 0° or 45° angle of incidence with a 90° separation of the beams, depending on the configuration.WISOPTIC offers a wide variety of PBS in a range of configurations including plate, cube, or lateral displacement.
