    BEL displays night vision defence devices

    The Defence Ministry’s Bharat Electronics Limited (BEL), Machilipatnam unit, is showcasing its state-of-the-art night vision devices including those used in Kargil war.

    This is the first public exhibition by the BEL in Machilipatnam.

    Optoelectronic devices

    Of them nine units of the BEL across the country, the Machilipatnam unit is engaged in development and production of optoelectronic devices that are meant for Indian defence.

    The devices being displayed for public on the Hindu College Grounds here during the ongoing ‘Masula Yuva Mahotsav’ are Passive Night Goggles, Passive Night Monocular, Passive Night Binocular and others.

    “Passive Night Sight for INSAS/LMG guns is a device that can be fixed to the guns to have clear vision of the target location. We are allowing the visitors to operate the devices to understand the functioning of the six varieties of devices in the exhibition”, BEL, Machilipatnam Assistant Engineer M.D. Khaja toldThe Hindu .

    Majority of the Night Vision Devices would function with the help of ‘Image Intensifier Tube that receives power from the ‘Stars’ and amplifies it thousands times more.

    Kargil War

    Hand-held Thermal Imager (HHTI) of the Machilipatnam BEL was used by the Indian Army during the Kargil war. “The HHTI device supplied to the Indian Army has helped a lot in finding precise location and accurate distance of targets during the Kargil war. It can locate accurately an aircraft within 10 km of distance while heavy vehicles can be tracked within four km of distance”, said Mr. Khaja.

    The Indian Army installs the HHTI on the watch towers at the strategic locations. Public can see and learn the use of the devices during the ‘Masula Yuva Mahotsav’, which will conclude by Thursday evening.

    We are allowing the visitors to operate the devices to understand the functioning of the six varieties of devices at the exhibition

    [​IMG]

    Passive Night Sight BEPNS-0808 is a high performance and compact night vision system designed for CQB Carbine. It can be mounted on pica-tinny rail of CQB Carbine. It is provided with invisible laser designator for easy engagement / designation of targets in stand alone mode.

    SALIENT FEATURES
    • II Tube with built in protection, against bright source ,reverse polarity protection & Automatic Brightness Control (ABC).
    • Hermetical sealing with N2 filling
    • Can be used in tandem with reflex sight
    • Built-in laser pointer
    HOLOGRAPHIC WEAPON SIGHT BEHWS-0803
    [​IMG]

    Holographic Weapon Sight is used for aligning the targets with precision, speed, and highest accuracy. It helps in enhancing the response time of weaponry. As the sight can be operated with both eyes open,facilitates an increased peripheral vision for an unlimited eye-relief and parallax free image. This parallax free image is created with a large and bright aiming reticle pattern allowing quick target acquisition particularly in close quarter combat situations.


    SALIENT FEATURES
    • Built-in range approximation reticule for instant target acquisition and gun firing
    • Mounting is on sturdy rail
    • Meets environmental specs as per JSS 55555
    • Self contained optics preventing complete blockage of laser light source and allowing usage of optic by operator in passive mode
    • Affords the operator for full use of the optic even if optical surfaces are obstructed due to moisture,thick fog and extreme environmental conditions
    • Target acquisition even if the optic is partially damaged
    • Complies with laser emission safety regulations Auto power shut down facility

    [​IMG]


    Advanced Night Weapon Sight is a high performance, water proof and compact night vision system designed for small arms like INSAS Rifle, AK-47, Sniper Rifle etc.

    By changing the mount, can be mounted on any of the above mentioned weapons.


    SALIENT FEATURES
    • High Performance II tube with built-in protection against bright source.
    • Bright light cut-off circuit.
    • Powered through single AA battery.
    • Available with 4X and 5X Objective lens.

    Another one from TATA

    Night Vision Devices

    Night Vision Devices (NVDs) is one of the areas of strategic interest for Tata Advanced Systems Limited (TASL). TASL has entered into a partnership with Exelis Inc., the world leader in Generation 3 Image Intensification (II) based NVDs, to manufacture and supply these systems to Indian Defence market. These systems will enable the security forces to achieve Battle Field Transparency even under low ambient light conditions and night, thereby significantly enhancing night operations. As part of our drive towards achieving indigenisation, TASL has set up a production facility in India, for assembly and manufacture of sub-assemblies and complete systems.

    Types of NVDs

    [​IMG]

    TASL provides a range of NVDs, which will enhance the situational awareness in the tactical battle space. These NVDs are based on designs that have been successfully used by Defence and Security forces across the world in theatres ranging from urban environments to dense forests. Manufactured in partnership with Exelis Inc. at our facility in Noida, TASL offers the following devices based on Gen-3 Image Intensification Technology:

    • Night Vision Monoculars
    • Night Vision Binoculars
    • Bi-ocular Night Vision Devices
    • Aviation Night Vision Goggles
    Exelis Inc

    Exelis Inc. is the leading manufacturer of night vision systems for the U.S. armed and allied forces, producing more Third Generation (Gen-3) night vision devices per year than all of its competitors—worldwide—combined. Exelis has manufactured more than 65 percent of the U.S. military’s Gen 3 equipment, and have delivered more than one million Gen 3 image intensifier tubes.

    Exelis’ achievements are the result of more than 50 years’ experience in all phases of night vision research, development, production and support. They have pioneered the development and production of the Gallium Arsenide (GaAs) Gen 3 image intensifier tube during the early ‘80s and have since delivered more than 10,00,000 systems to customers worldwide. NVDs by Exelis are human-engineered for long wearing comfort and can be hand-held or helmet-mounted or head-strap mounted for hands-free operations.

    Key features

    • Long life and Reliability of Image Intensifier tube upto 10,000 hrs of operations
    • High resolution, high luminous gain, and very high photo-response in visible and near infrared spectrum
    • Variable gain control for enhanced performance in altering light conditions
    • Automatic Brightness Control (ABC) and Bright Source Protection functions to manage rapid changes in scene brightness
    • Multifunctional (hand-held, head/helmet/weapon mounted)
    • Flip-up/down capability
    • Individual eye adjustment, Tilt, vertical and fore-aft adjustments
    • Powerful IR illuminator with wide or narrow beam capability
    • Greater depth perception for off-road driving and high speed navigation at sea
    Advantages of Gen-3 over Gen-2 Night Vision devices

    • Reliability: Upto 10,000 hrs of high performance operational life resulting in lower life-cycle cost
    • Photo-response: Gallium Arsenide cathode providing better photo-response for target recognition in starlight conditions.
    • Luminous Gain: Advanced Micro-Channel Plate with ion-barrier film for greater luminous gain.
    • High Light Control Functions: Rapidly adapt to changing brightness levels regardless of “auto-gating”.
    • Cosmetic standards: Reduced spots and image defects than Gen-2 tubes.
    • Environmental stability: Survive higher storage temperatures due to improved image intensifier tube housing material.
    Training, Repairs, Maintenance and After Sales Support

    In addition to manufacture and supply of Night Vision Devices, TASL will provide on-site training to the operators as well as maintenance personnel of NVD customers to ensure optimal exploitation of these state of the art systems and maximum availability to the warfighter. Furthermore, TASL will ensure best in class after sales support to its customers backed by the legendary Tata Guarantee of Trust.
