The latest fluorescence filters from HHV will meet
the challenging task of detecting the explosive in surface/ land mines with handheld bomb detectors.
The
Bangalore based Hind High Vacuum Co. Pvt. Ltd. (HHV), announced that
its thin films technology division has exclusively developed a ‘fluorescence filter’ for handheld bomb detectors. HHV’s
’fluorescence filter’ which is integrated
with the explosive detecting device, allows to a particular wavelength of
fluorescence light and this will be enhanced for accuracy of the detection
process.
The detector uses source of light to stimulate the sensing
element (fluorescent polymer (FP)) coated inside the bore of a glass capillary
tube to emit fluorescent light.
At the same time, air / vapour surrounding the area is pulled
through the bore of the sensing element. Traces of explosive vapour in the
air/vapour stream will adsorb to the FP and attenuate its characteristic
fluorescence. This change is detected using optical and electronic components
designed to maximize sensitivity.
This is a
path breaking initiative by HHV. Established
in 1965 at Bangalore to develop Indian self-reliance in high vacuum
technology, HHV has now grown into a leading
global player involved in the design, development and manufacture of
off-the-shelf and customized equipment and products in the fields of
Vacuum Technology, Solar Photovoltaic Energy and Thin Films Technology.
Announcing the same, Mr
Prasanth Sakhamuri, Managing Director of HHV said, “We are extremely
pleased to have indigenously developed this product at our facility. HHV’s
pioneering spirit to develop new technologies and synchronise its expertise in
thin film technology with applications has resulted in this break through. HHV’s thin film technology group has some of
India’s best thin film scientists and infrastructure to make coated optical
components for many precision applications.”
Thin film products of HHV are being used by leading companies
in a wide range of segments like defence, space, biomedical, industrial and
many more. One of its proven products is “fluorescence filters”. HHV has been
developing and producing these fluorescence filters with advanced deposition
technique like Ion Assisted deposition (IAD) which are addressing many
applications like to instantly diagnosing hardcore diseases etc.
The fluorescent filters
produced by HHV has high
specificity, steep edges, multiple dielectric layers and narrow bandwidths with
an advanced deposition technique ‘Ion Assisted Deposition (IAD)’ which facilitates an environmentally hard coatings, superb
resistance and high transmission. These filters are optically monitored during
growth to ensure minimal deviation from design specifications and ensuring
overall high quality filter performance.
HHV’s thin film division is equipped with twelve
sophisticated vacuum coaters with necessary modern accessories and processes in
a clean room environment to ensure the products and meet MIL standards. The
division has earned a reputation for consistent, reliable product performance
and is certified for ISO: 9001:2000, BS OHSAS 18001: 2007 and ISO
14001: 2004 quality systems
