Welcome to

Hole Detector Technologies

Founded over 55 years ago as Nash & Harrison Ltd., Hole Detector Technologies, a partner of R.K.B. OPTO-ELECTRONICS, INC. (R.K.B.) was the first commercial on-line web inspection manufacturer and supplier in the world. Today we are a leader providing web based material manufacturers with reliable, accurate and quality machine vision imaging and inspection technologies unequaled in cost, performance and reliability. With our leadership, application knowledge and expertise, we offer products, systems, solutions and services that allow our customers to improve their quality assurance initiatives, process control, productivity and traceability.

In the late 1950's, we designed and patented many of the void and defect fault technologies in use today by many multinational companies. So reliable is our technology, that technologies provided over 40 years ago are still on-line performing with unprecedented reliability. In 1960, when we were known worldwide as Leigh Instruments Ltd. (Division of Leigh Control, Canada), we designed, patented and successfully introduced infrared, phototransistor flaw detection technologies for the identification of dirt defects in a wide variety of web based materials. In the 1970's we became the first company to introduce and provide reliable camera based inspection for quality assurance called the "Vidicon 7000". This innovative technology changed how many film manufacturers handled their quality initiatives and laid the groundwork for our revolutionary technology yet to come.

In 1976, our company relocated from Canada to the United States to improve its logistics and purchasing power where it has remained today. In 1980, William Dobbie, considered one of the most renowned engineers in the web inspection industry and Director of Engineering for Leigh Inspection Division, acquired their inspection technology division and founded R.K.B. OPTO-ELECTRONICS, INC. In 1987, we introduced the first successful CCD line scan inspection system for use on high end watermark and security papers. In 1992, we designed and patented our high resolution and very successful coating scratch and streak detection technology. Using the most advanced defect signal processing technologies, experience and leading sensing solutions, our coating streak and scratch inspection technology monitors any coated web material with detection capabilities down to sizes that no other technology or company can compare to. Not only industry proven! our streak detection technology will perform with unprecedented performance no matter what your production process speed may be. This advanced scanner truly represents a quantum leap forward in high-speed, on-line defect fault imaging and inspection.

Many of our employees have been with us for more than 30 years with key personnel celebrating more than 30 years with us. Our technological expertise coupled with our leading market position and support disciplines provide all of our customers with leading edge technology that is unsurpassed in performance. Since we rely on openness and cooperation unlike other suppliers, we can offer customers the ability and flexibility to customize there inspection solutions to meet their quality assurance initiatives. This allows us to become an integral part and valuable link in the overall process of web based material manufacturing. In addition to our Corporate Headquarters in New York, we have sales and service offices located in Spain serving the European Community and China serving the Asian-Pacific Rim communities. We also has affiliated partners and offices throughout the world.
