Process oriented manufacturing : Over 350 Processes
High voltages and ultra low currents : 7,000 Volts / < 0.1 nA
Special Raw materials & components : Processing and Treatment Precision Fabrication & Assembly : < 5 μm
Ultra high vacuum levels : < 10-9 mbar
Storage & Assembly : Controlled climatic conditions (Relative Humidity,Temperature and particle count)
Maintenance of plant and utilities : Multi skills and Experience
Due to the indigenous capability at BELOP to manufacture I.I. Tubes and its modules from the component level, makes it the only in-depth manufacturer of I.I. Tubes in India, thereby making India to be self reliant to meet the needs of its armed forces. It has the requisite testing, repairs and maintenance facilities that are essential to completely avoid foreign dependency.
This is also consistent with the “Make in India” philosophy of the Honourable Prime Minister and ensures that there is no dependence on imports and freedom from foreign sources for repair of Image Intensifier Tubes.
