Instruments Research and Development Establishment


About Lab

Instruments Research and Development Establishment (IRDE), Dehra Dun, under DRDO, is devoted to research, design, development and technology transfer in optical and electro-optical instrumentation primarily for the Defence Services. The origin of IRDE dates back to the establishment of Inspectorate of Scientific Stores in 1939 at Rawalpindi (now in Pakistan) with the responsibility to inspect the tele-communication equipment used by the Army in India. This AHSP underwent many organisational and locational changes until it took the shape of Technical Development Establishment (Instruments & Electronics) covering both R&D and AHSP functions in the fields of instruments and electronics and was located at Dehra Dun. The Establishment, during subsequent years, shed some of its R&D and AHSP responsibilities and came into existence, in its present form as IRDE on 18 February 1960.

Mr. Benjamin Lionel

Mr. Benjamin Lionel, Scientist H (Ouststanding Scientist) has taken over as Director, Instruments R & D Establishment (IRDE) with effect from 01st July 2016. He obtained M. Sc. in Physics from Madurai Kamraj University in 1983 and M. Tech. in Applied Optics & Optical Instrumentation from IIT, Delhi with specialization in Design & Development of Opto-Electronic Systems in 1985. He received a training at Centre for International Trade & Security, University of Georgia, USA in year 2004.

Mr. Benjamin joined IRDE, Dehradun in 1985 as Scientist B and worked for four years in optical design area. In 1989, he joined CVRDE and worked in Fire Control Systems for Tanks & AFVs for 14 years at various designations. In year 2006, he was appointed Counsellor at TAD, London and performed various duties for three years. In year 2009, he joined CVRDE as Addl. Director (IFCS & TEPS) and worked for two years. In year 2012, he was appointed DCV&E in DRDO Hqrs. For two years. In year 2014, he took over as Director (Vehicles) in DRDO Hqrs. and later was appointed Head Programme Office (HPO II) in year 2015.

His main contributions have been integration & evaluation of Fire Control Systems of MBT-Arjun and proving the Weapon System performance of Arjun. He has in-depth practical exposure and knowledge of Fire Control Systems of T-55, T-72, T-90 and MBT-Arjun tanks. He has evolved various techniques for proving the performance of AFVs. As a team leader, he got developed Gunnery Simulators for MBT-Arjun, created container based infrastructure at PFFR, Pokhran for supporting the DRDO teams during trials and resolved several issues with users in the course of trials.

Mr. Benjamin has several technical papers & reports in journals & international conferences to his credit. He has been awarded DRDO Technology Award in year 1995 for successful integration and interfacing of Fire Control Systems of MBT-Arjun and Technology Group award in year 2004 for Development of Muzzle Reference System of MBT-Arjun.Mr. Benjamin is Lifetime member of Optical Society of India (OSI) and Instrument Society of India.
