Unlike most of other companies Visus is not a “one – product” company and offers a complete range of technologies for virtually all LED markets including LED chip and lamp design. A control of a complete “photon supply chain” starting from an optimized photon generation and extraction at LED level and down to secondary light management optics enables to attain maximal performance not possible when considering only one system component, e.g. LED, lightguide panel or BEF.
All our products employ ground-breaking patented optical architecture belonging to FID (Flat Illumination Device) class of optical systems. In contrast to existing ubiquitous illumination devices FIDs operate with a sharply reduced number of powerful compact light sources and redistribute their flux with a surgical precision using hybrid multilayer waveguides and photonic couplers. A combination of optical technology along with novel waveguide materials and LED packaging and encapsulation culminated in a large family of ultra-slim and power efficient FIDs for virtually all of diversified multibillion markets for general and special illumination devices.
Key technologies include:
- ExFRACTOR™ waveguides with optimized flux extraction patterns.
- Optimized NLW (Non-Linear Wedge) Extratorless waveguides with reduced profile & weight & cost and no need for extraction pattern,
- HOW™ Hybrid Optical Wave guides for LCD backlights, including large LCD TVs, general & automotive illumination and signage.
- TilEx™modular backlights for large LCD TV.
- Ultra-thin “Functional Flat Fiber” waveguides for LCD BLUs.
- Ultra-thin “Flat Fiber” waveguides for keypad & keyboard backlighting
- FoCOUPLER™ energy conserving ultra - compact foconic flux couplers for LED primary & secondary optics.
- Brightness Enhancing & Diffusing Film components (BEFs etc):
8.1. SADO ™ Stacked Amplifying Directional Optical Transflector Film.
8.2. SHUTLE ™ Shaped Hollow Ultra-Thin Luminance Enhancement Film - Advanced Microreplication Technology for microprismatic extractors
- KEREN ™ CAD/CAM Software Package is a most advanced pioneering proprietary software package enabling a fully automatic synthesis of various non imaging optical systems
Proven track record. Visus has been at a cradle of inventing a number of key optical systems and components which have turned into core technologies in LCD and lighting industries. In mid 80’s it pioneered a development of light guides with distributed light extractors turned later into an indispensable core component of all LCD backlights. It also used for the first time 3M’s SOLF (developed for a totally different application, namely hollow tubular light guides) for LCD backlights. Later it became known as BEF, another core component used in every LCD. In a general lighting first computer generated asymmetrical reflectors (car headlights, road & projection lighting) have been licensed by Visus. Today many of European cities and highways are lighted by these uniquely optimized reflectors. In Visual Ergonomics our methods based on Visual Field Visibility analysis have become a standard approach for Visual Performance evaluation recommended by CIE, IPS and other international standard organizations.
VISUS concentrates on finding immediate novel technological solutions to rapidly changing market demands and establishing a toll position by continuing patenting its intellectual property and building a significant IP portfolio. In this regard, VISUS has a constantly growing number of omnibuses and CIP patents covering extensive technologies for compact illumination devices for virtually all of diversified multi billion markets for general and special illumination devices with a special emphasis of LED powered devices.
Visus continues to file under the CIP vehicle a number of follow-up patents relating to several classes of new illuminating systems, in particular to plastic light enhancing components (BEFs etc.), ultra bright LEDs (primary @ secondary optics) and LED powered lighting systems with energy conserving ultra compact optical couplers.
