Why in News

  • India is rapidly improving its combat readiness along disputed borders by upgrading tactical night-fighting equipment.
  • The Ministry of Defence signed a Rs 659.47 crore contract for Netro NW 3000 night sights.
  • Bharat Electronics Limited (BEL) opened a new electro-optics manufacturing plant in Andhra Pradesh to boost local production.

About Night Vision Devices

  • A Night Vision Device (NVD) is an advanced optical tool that helps military forces see clearly in pitch darkness, thick smoke, or camouflage.
  • Soldiers use these devices as handheld tools, weapon attachments, helmet-mounted goggles, or built-in sensors on tanks and aircraft.

How NVDs Work

  • Image intensification captures tiny amounts of natural light from stars, the moon, or infrared sources through an objective lens.
  • An Image Intensifier Tube (IIT) converts light particles into electrons and multiplies them rapidly.
  • The multiplied electrons strike a phosphor screen to create a bright, clear green or white image.
  • Thermal imaging uses microbolometer sensors to read heat signatures given off by human bodies, running engines, or weapons.
  • Thermal technology helps soldiers spot targets through total darkness, dust storms, thick jungles, and battlefield smoke.

Key Features of Modern NVD Systems

  • Modern Generation-III/IV sensors use automatic gating to deliver sharp target images with very little graininess.
  • Fused sensor technology combines thermal imaging and light amplification into one digital display for a complete view of the surroundings.
  • Advanced military goggles use Augmented Reality (AR) to show live tactical maps and target data directly in front of the soldier's eyes.

India's Growing Night Vision Capabilities

  • The Ministry of Defence ordered 29,762 Netro NW 3000 Gen-3 night sights from MKU Ltd and Medbit Technologies for frontline SIG 716 assault rifles.
  • Local thermal sights are being added to BMP-2M infantry combat vehicles.
  • The Indian Air Force (IAF) has received Netro NB-3100 Gen-III aviation goggles for LCH Prachand and LUH operations.
  • BEL set up a Rs 362 crore facility in Nimmaluru, Andhra Pradesh, to build night vision devices, missile infrared seekers, and anti-drone systems.
