Norland Products Inc. began in 1960 as a manufacturer of specialized gelatin used in the electronics industry.

During the past 43 years Norland have developed a line of products that command considerable interest in the market place. Our relationship to the camera industry led us to the development in 1973 of a line of ultraviolet curing adhesives originally used for bonding camera lenses, but later branching out into military optics, fiber optics, and electronics.

Norland have two manufacturing locations, one in New Jersey USA and our sister plant, Kenney & Ross, in Nova Scotia,Canada. Some of the products we manufacture include fish gelatin, ultraviolet curing optical adhesives, UV curing electronic adhesives, and fiber optic equipment.

Most of our products are unique and must have high performance properties with definite advantages to be accepted over alternative products in the market place. For instance, our ultraviolet curing optical adhesives are one part adhesives that cure in seconds when exposed to UV light and are used for bonding lenses, prisms and other precision optics. The speed and accuracy allowed by these products are advantageous to the user but it is the high optical quality and superior physical performance that leads the customer to choose it over other products on the market.

For the last 10 years we have been supplying interferometric test equipment to the fiber optics industry. This has been an evolutionary process because of the changing needs of the customers to meet more rigorous standards. By investing the necessary time and money in the computer technology that has become available in the last few years(speed and memory), we have made great strides in advancing interferometric technology to new levels.
