All standard AR coatings can be customized for your particular application. More... Band Pass/Band Reject Filter Coatings Band Pass Filter and Band Reject Filter coatings are used to create a type of wavelength selection filter operational over a specified wavelength band from the UV to the far IR. A Band Pass Filter allows only the wavelengths in the specified range to pass through the filter, while blocking wavelengths outside of the transmission region with high rejection ratio. A Band Reject Filter blocks a specific wavelength range with high rejection ratio, while transmitting wavelength regions on either side of the rejection region. More... Bullseye® Apodizing Filters Coatings Bullseye® Apodizing Filters Coatings are a part of the Bullseye® apodizier line of customizable gradient filters. The Bullseye® Apodizing Filters are used to eliminate undesirable intensity variations in optical systems. The custom specified density function can either decrease (dark-to-light)or increase (light-to-dark)radially from the center of the substrate. More... Attenuation Filter Coatings Attenuating Filter Coatings, at the most basic level, are thin film coatings, which reduce the amount of light energy transmission in an optical system. For static applications, a fixed ND (neutral density) filter provides a constant level of transmission over a wide wavelength band. A more complex variable (or gradient) filter provides a density change over a custom defined region. The variable function can be defined as linear, circular, or radial depending on the substrate needs, and in either continuous or step. More... Conductive Coatings Thin film Conductive Coatings can be applied as a uniform plane across a substrate, as bus bars on the sides of a substrate, or as a custom pattern with geometries down to 10um. Various metals can be used depending on the wavelength range of required performance. Transparent Conductive Coatings are also deposited utilizing thin metals or specially designed materials, such as ITO or AZO. More... Dichroic Filter Coatings (also known as Color Separation Filter Coatings): Dichroic Filters are sometimes known as color separation filter coatings because their purpose is to separate incoming light into distinct wavelength regions. Commonly used to extract a narrow wavelength band for entertainment or lighting effects, they can also be used as hot mirrors or cold mirrors to separate infrared light from visible light. Dichroic coatings achieves color or wavelength separation with a much higher degree of accuracy than conventional filters. More... Infrared Thin Film Coatings Infrared (IR) Coatings effect light that extends from the edge of visible red (700nm) to the far infrared (approximately 50um for Reynard Corporation capabilities). Any type of filter (LWP, SWP, BP, etc) or mirror coating that can be produced in the visible spectrum can also be implemented to work in the infrared. The difference in design is the starting choice of substrate and coating materials used to implement the required function, as reflection and transmission characteristics of individual materials change dramatically at different wavelengths. Reynard Corporation is highly experienced in the design and manufacturing of IR filters and mirrors. More... Laser Protection Thin Film Coatings High performance thin film Laser Protection Coatings, are designed to withstand higher energy conditions than classical thin film designs. Improved performance comes from the use of material sets with low absorption and higher melting points as well as through process improvements, such as the use of IAD. More... Longwave Pass Filter Coatings (LWP Filter Coatings) Longwave Pass Filter Coatings (LWP) are used to create a type of wavelength selection filter operational over a specified wavelength band from the UV to the far IR. Wavelengths smaller than the filter transition point are blocked with a high rejection ratio, while wavelengths longer than the transition point are transmitted. The transition point is application specific and static as defined by the customer. More... Multi-Band Thin Film Coatings Multi-Band Thin Film Coatings are used to create a type of wavelength select filter operational over customized distinct wavelength bands from the UV to the far IR. The filters are custom designed for applications that require multiple transmission or rejection bands that are non-contiguous. A filter that transmits the 3-5um (MWIR) band as well as the 8-12um (LWIR) band, while blocking the regions in or around these transmission bands is an example of a multi-band filter. More... Short-wave Pass Filter Coatings (SWP Filter Coatings) Short-wave Pass Filter Coatings (SWP) are used to create a type of wavelength selection filter operational over a specified wavelength band from the UV to the far IR. Wavelengths smaller than the filter transition point are transmitted, while wavelengths longer than the transition point are blocked with a high rejection ratio. The transition point is application specific and static as defined by the customer. More... Trichroic Filter Thin Film Coatings Trichroic Filters are used to precisely split incoming light into three separate wavelength bands of red, green, and blue, or alternatively to recombine such bands. Applications for Trichroic Filters include multi-sensor camera systems, where the three separated bands are detected by three separate CCD arrays, and projectors, where the Trichroic Filter recombines the red, green, and blue light sources into the presentation image. More... Ultraviolet (UV) Filter Thin Film Coatings Ultraviolet (UV) Thin Film Coatings are designed to work over shorter wavelengths from the edge of the visible spectrum (400nm) down to 180nm. Any type of filter (LWP, SWP, BP, AR, etc) or mirror coating that can be produced in the visible spectrum can also be implemented to work in the UV. More... Visible Thin Film Coatings Visible Thin Film Coatings in the visible spectrum cover the wavelength range from 400nm to 700nm, which correspond to the spectrum detected by the human eye. Coatings by Reynard Corporation modify the transmission and/or the reflection characteristic of an incident light source to produce a desired effect. Thin film designs can be specified as part of our large selection of standard types,or customized for application specific requirements. Types of coatings offered include, but are not limited to, longwave pass (LWP), shortwave pass (SWP), dichroic, attenuation (variable/gradient), anti-reflection (AR), and mirror coatings. More...

Information
|
Thin film coatings are extremely thin layers of materials (such as TiO2, SiO2, MgF2, gold, aluminum etc…), which can be applied to the surface of a substrate like glass, metal, crystals, or ceramics, to effect a change in its optical properties. Effects such as reflection, refraction, anti-reflection and conductivity can be produced and modified by expert calibration of material selection, the number of coating layers, and the respective thicknesses of each thin film layer, all in relation to the incidental wavelengths of light.
