Anti-Reflection for Scanners and Cameras
The Optimised AR Coatings are designed to obtain maximum AR performance in the exact application-specific wavelength range. It reduces reflections to an absolute minimum and increases undisturbed transmission in the desired range. This is highly relevant in certain camera, scanner, and sensor applications. RED AR, NIR AR and 1550 AR are not standard products, why the availability often depends on the concrete customer project.
Red AR (anti-reflection)
PSC offers Red AR specially designed for barcode readers and the like. An Optimised AR Coating is applied to one of our red colour filters materials (i.e. Solaris S706). This means that the filter's transmission is improved to almost 100 % in the red range, eliminating almost all signal degradations caused by surface reflections.
Anti-Reflection for Near Infrared filters (NIR AR)
The NIR AR is often applied to our Solaris™ IR 306 filter. This means that the filter's transmission is improved to almost 100 % in the NIR range. Certain traffic cameras and iris recognition applications apply our NIR AR solution for faster and more precise detections, maximizing the signal-to-noise ratio in the signal detection.
Anti-Reflection for the 1550 spectrum (1550 AR)
The 1550 AR applied on Solaris acrylic provides a filter transmission up to 98 % in the 1550 nm range combined with only 0.5 % reflectance (double-sided measurement). The topcoat is Hydrophobic and abrasion resistant, and the acrylic base material makes the filter lightweight and much more impact resistant than glass. These properties make 1550 AR perfect for filter and cover lens solutions in 1550 nm LIDAR camera applications. The 1550 AR is for applications such as ‘eye-safe’ infrared laser rangefinders using 1550 nm lasers and other LIDAR derived products for robotics, archaeology, geology, military or surveying purposes.
