Bangalore based Hind High Vacuum Company (HHV), has developed ‘fluorescence filter’ for bomb detectors.
Prasanth Sakhamuri, Managing Director of HHV said, “The fluorescence filters from HHV will meet the challenging task of detecting the explosive in surface/ land mines with 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.
Sakhamuri, Managing 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 breakthrough. 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.
