AR coated solutions for machine vision, sensing and scanning applications

In contrast to displays/human eye solutions, machine vision applications only benefit from specific wavelengths within the VIS range (red), or longer wavelengths than those of visible light (NIR). For these applications, PSC has developed a range of unique and very effective Anti Reflective surface treatments called Optimised AR Coatings. The Optimised AR is applied to our acrylic sheet material.

Near infrared AR coated acrylic (NIR AR)

The NIR AR is an AR coating optimised for applications operating in the near infrared area. Most often, the NIR AR is applied to our Solaris™ IR 306 filter. This means that the filter's transmission is improved to almost 100 % in the NIR range. A wide range of applications, such as ANPR/traffic cameras, facial recognition and iris scanners, NIR TOF devices, etc. utilize our high performance NIR AR solution for faster and more precise detections, maximizing the signal-to-noise ratio in the signal detection.

Red AR

PSC offers Red AR, an anti reflective coating especially designed for barcode readers and the like operating at or around 670nm. An Optimised AR Coating is applied to one of our red colour filter 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 reflective coated acrylic for the 1550 spectrum (1550 AR)

The 1550 AR coating 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 the 1550 AR the perfect filter for protection of the sensitive optics and lenses in 1550 nm LIDAR applications. The 1550 AR is for applications such as ‘eye-safe’ rangefinders using 1550 nm lasers and other LIDAR derived products for robotics, archaeology, geology, military or surveying purposes.

VIS / NIR AR

The VIS_NIR anti reflective coating has been developed to perfectly match applications where Full VIS and high NIR performance is critical, i.e. RGB, RCCB, RCCG etc. camera systems, working alone or in combination with Near Infrared LIDAR or TOF (time of flight) devices, providing range detection, contour scanning or focus setting of the camera system.

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 VIS_NIR AR the perfect filter for protection of sensitive optics and lenses.

The VIS_NIR AR solution is sheet to part which enables full design freedom.

The VIS_NIR AR is for applications such as high performance bar code readers, dimensional measurement devices, and inline machine vision systems.

Partial VIS / NIR AR

The partial VIS_NIR anti reflective coating has been developed to perfectly match applications where balanced VIS combined with Extreme NIR performance is critical. The extreme NIR performance allows for perfect signal quality and s/n ratio for camera systems optimized for low light application environments. Compared to VIS_NIR AR, extreme performance in the 850-950nm has been prioritized over deep blue performance.

NIR LIDAR or TOF (time of flight) devices also benefits from this by faster detection and/or better performance at longer ranges.

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 partial VIS_NIR AR the perfect filter for protection of sensitive optics and lenses.

The partial VIS_NIR AR solution is sheet to part which enables full design freedom.

The partial VIS_NIR AR is suitable for applications such as long range VIS_NIR licence plate detection systems and inline machine vision systems where superior NIR performance for long range functionality is required.
