Dielectric Hr Mirrors

Characteristics of dielectric film Mirrors. 1.The dielectric film reflector is made out of the interference principle of overlapping multilayer films. 2.The reflectivity of the dielectric film reflector is high, which can be close to 100%. The mechanical hardness of the film is high, and resistant to cleaning operations. 3.The reflector of a dielectric film is narrower than a metal film, and is closely related to the angle of incidence. 4.The reflectivity and reflected bandwidth of a dielectric film reflector is influenced by the polarization state of the incident light in addition to the incidence of 0 degrees. 5.A dielectric film reflector can be used for a strong laser, but the damage threshold test is a destructive test.

Optical Mirror PARAMETER: A dielectric mirror, also known as a Bragg mirror, is a type of mirror composed of multiple thin layers of dielectric material, typically deposited on a substrate of glass or some other optical material. By careful choice of the type and thickness of the dielectric layers, one can design an optical coatingwith specified reflectivity at different wavelengths of light. Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques. Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser. Mirrors of this type are very common in optics experiments, due to improved techniques that allow inexpensive manufacture of high-quality mirrors. Examples of their applications include laser cavity end mirrors, hot and cold mirrors, thin-film beamsplitters, and the coatings on modern mirrorshades. Dielectric mirror is an optical mirror made of thin layers of dielectric coating deposited on an optical substrate. We offer dielectric laser mirrors for fixed, narrowband or broadband wavelength applications covering wavelength ranges from UV to IR. Wide selection of round, elliptical or custom shapes as well as flat, spherical, cylindrical surface mirror.

A protective dielectric overcoat is layered over the gold to help protect it from damage and make cleaning easier. These optics provide >96% average reflectance from 800nm to 20μm. The mirror  coated with metal (Au, Al, or Ag) over coated with silicon monoxide(SiO2). Metallic coatings have low peak reflectance, mechanical durability and damage threshold, but they have extremely broadband and low cost. They are insensitivity to angle of incident light and polarization.

Mirrors Spherical Reflection Mirrors, Off-Axis Parabolic Mirrors, Plano Mirrors With High Reflection Coating Optical Mirrors are designed to reflect light for a variety of applications, including beam steering, interferometry, imaging, or illumination. Optical Mirrors are used in a wide range of industries, such as life sciences, astronomy, metrology, semiconductor, or solar. Hyperion Optics offers a range of laser, flat, metal substrate, focusing, or specialty Optical Mirrors in a multitude of reflective coating options, including Protected Aluminum, Enhanced Aluminum, Protected Silver, Protected Gold, or Dielectric. Choosing the proper reflective coating option ensures high reflectivity of the needed wavelength or wavelength range. Optical Mirrors designed for laser applications are optimized for the given laser wavelength. Additionally, Optical Mirrors designed for lasers feature damage thresholds that are suitable for the designated laser. Metal substrate Optical Mirrors are ideal for applications requiring a constant coefficient of thermal expansion between the Optical Mirror and the mount. Optical Mirrors with a concave surface are ideal for light focusing applications.

Hanzhong Brisun Optics Co., Ltd. Is the high High precision optical element manufacturer provides customized production of Various optical lenses, including spherical lens, cylindrical lens, optical window, mirror, prism, filter, metal base mirror and other high-precision optical elements. The base materials include various optical glass, fused quartz, calcium fluoride (CaF2), zinc selenide (ZnSe), germanium (GE), silicon (SI), sapphire, metal and other materials. And provide antireflective film, high reflection film, spectroscopic film, metal film and other optical coatings. Mirrors are used for beam turning, interferometry, imaging or illumination. Using polished glass or metal as the substrate, the light beam irradiates the surface to form specular reflection. In order to obtain as much reflected light as possible, a layer of reflective film is often plated on the substrate, including metal film and dielectric film. The commonly used materials of metal films are aluminum, silver and gold. Aluminum has high reflectivity from ultraviolet region to infrared region. At the same time, a layer of alumina can be formed on the surface of aluminum, so the film is firm and stable. The silver film has high reflectivity in the visible and infrared regions, and the polarization effect is the smallest when the incident angle changes. Gold film has high reflectivity in the infrared region, and its strength and stability are better than silver film, so it is often used for infrared reflection. The metal film is soft and easy to be scratched and damaged, so a protective film is often plated outside the metal film. The metal film mirror is not sensitive to the incident angle, and can meet the geometric reflection conditions. At the same time, it can be used in a relatively wide wavelength range.
