• Electronics & Instrumentation

    CSIR recognized the long-term significance of the crucial role of electronics in the overall national development and initiated R&D efforts in this area as early as in the fifties. Today, it has emerged as a major R&D agency with nearly a dozen laboratories contributing towards various aspects of electronics and instrumentation. CSIR’s R&D in the area of electronics relate to strategic sectors, e.g., space and defence, where technology/product may be denied to India; and locale-specific applications like modernizing the agro-based industries, disaster/environment management appropriate medical and analytical equipment/instruments, etc.


    CSIR mandate is to:

    • Undertake research design and development of electronic components/systems and instruments to meet the requirements of strategic sectors such as defence and space, industry, agriculture, healthcare, etc.
    • Undertake repair and maintenance of sophisticated instruments. Offer technical assistance to industries and other users by way of fabrication, testing, calibration, analysis and performance evaluation.
    • Provide advanced training in instrument technology aimed at human resource development for the benefit of precision instrument industry and R&D institutions.
