  • TEI, founded in 1968, is an innovative company developing new instruments under the motto "opening up the future of photonics and electronics". We believe that precision instruments are essential for manufacturing quality products. TEI successfully developed the world’s most advanced ultra-high sensitive photo-counting technique in 1976 under a Government supported contract "Analytical Instrument for Evaluating the Degradation of Oil using Optoelectronics"

    From their base in Miyagi, Japan, almost 500 instruments have been supplied to companies concerned with the stability of materials to oxidative degradation, and to researchers concerned with the sensitive detection of peroxides in food or biomaterials, or the estimation of antioxidant ability.

    Especially polymer & plastic processors looking to improve product quality, determine the cause of defects, or optimize all stages of their moulding processes, are increasingly making use of chemiluminescence as an invaluable monitoring tool. A key merit of TEI’s ultra-sensitive instrument is its ability to detect the very early stages of degradation.

    In Japan, the TEI instrument is widely used across the advanced material sector including medical plastics, elastomers, rubber, and in the development of new materials and in the formulation of medical devices. Applications are well established for catheters, implants, tubing materials, films and tapes – and for determining drug stability.

    TEI’s instruments have been used in many Research Institutes in other countries, i.e., Sweden, United States, Australia, and across Asia. More than 450 papers have been published by researchers using our CL apparatus in the field of chemistry, biochemistry, food, medical, high polymers, oil and fats, food, etc.

    TEI is also a manufacturer of laser controlling units and systems and also is involved in developing laser excitation components.

    The Trading Division in TEI deals with many companies as a sales agency for different types of laser equipment, analytical instruments, and electronic devices. TEI has an enviable reputation with its customers for first class reliability gained through meeting or exceeding needs through their technical service network.
