Anti-Reflective Coatings and Beamsplitters - A Synergetic Relationship

Posted by The VisiMax Team on May 31, 2018 8:17:10 AM

Development of high performance optical systems frequently requires the use of an interferometer to detect imperfections and ensure high precision performance.  Most interferometers rely on beamsplitters as do other optical applications such as aeronautical and automotive heads up displays. However, an uncoated beamsplitter will often allow stray light to be reflected in addition to the beam reflecting off of the primary surface. To achieve the desired level of performance, beamsplitters are often used in conjunction with anti-reflective coatings to not only split a beam of light into two, but also to enhance the beamsplitter’s efficiency and prevent ghost reflections caused by stray light.

Common Uses of Optical Filters: An Example of LED Emission and Color Perception

Posted by The VisiMax Team on Jul 13, 2017 8:50:00 AM

A light source, whether natural or man-made, typically emits a broad spectrum of wavelengths, including ultraviolet and infrared. In some applications, this full spectrum is acceptable or even desired. In others, however, it may be necessary to limit the wavelengths passing from the light source. This is where optical filters come in.

Filtering Light: Optical Filters Designed to Provide More Desirable Lighting

Posted by Chris Murphy on Mar 3, 2017 9:22:00 AM

Optical filters are generally used to selectively transmit or reject a narrow wavelength band or a range of wavelengths. VisiMax can provide a variety of optical light filters; one area of application is filter coatings. VisiMax Process Color Filters selectively and accurately pass the light of a small range of colors while reflecting other colors. Our heat-resistant dichroic filter coating technology produces durable interference filters that render light with precise spectral control.
