Ocean Optics unveils 1100- 1900nm InGaAs spectrometer
The firm’s high-resolution NIRQuest512-1.9 utilises one of Hamamatsu’s indium gallium arsenide detector
Ocean Optics has added another option to its small- footprint near-infrared spectrometer line with the NIRQuest512-1.9.
The NIRQuest512-1.9 is suited to applications ranging from monitoring changes in food production and chemical processing to characterising lasers for semiconductor assembly and medical treatment.
time. High gain mode operation is available for applications where sensitivity is paramount.
Headquartered in the USA, Ocean Optics is a supplier of solutions for optical sensing - fundamental methods of measuring and interpreting the interaction of light with matter.
EVG wins first order for ZoneBOND technology in compound semiconductor market
The firm is expanding its proprietary ZoneBOND temporary bonding/debonding process into the CS industry with its first order from a major player
EV Group (EVG) has received an order for its EVG850 temporary bonding/debonding (TB/ DB) systems from a leading maker of compound semiconductor-based components.
This order marks the first implementation of ZoneBOND TB/DB technology in the manufacture of compound semiconductors, whose rapid growth is being driven by unrelenting demand for smart phones and other mobile products.
NIRQuest512-1.9 system
NIRQuest512-1.9 has a high-stability, 512-element Hamamatsu InGaAs-array detector and is available with multiple grating and optical bench options for optimising performance between 1100 and 1900 nm.
The standard NIRQuest512-1.9 comes with a 150 lines/mm grating, 25 µm entrance slit and a non- fluorescing longpass filter that transmits over 1000 nm. The filter helps to mitigate second-order effects.
NIRQuest512-1.9 has external hardware triggering functions that allow users to capture data when an external event occurs, or to trigger an event after data acquisition. Spectrometer operation is controlled using SpectraSuite software, a modular, Java-based spectroscopy platform.
The low dark noise characteristics of the NIRQuest make it possible to integrate the spectrometer (or expose the detector in the spectrometer to light) for longer durations, which is useful in low light level environments. Signal to noise ratio at full signal is over 15000:1 at 100 millisecond integration
“The compound semiconductor market has always been a front runner in driving the introduction of new temporary bonding/debonding technologies – starting from solvent-assisted debonding, tape debonding, slide off debonding and now ZoneBOND,” notes Thorsten Matthias, business development director for EVG.
“EVG has provided TB/DB equipment to the compound semiconductor market for over 10 years. And, the introduction of ZoneBOND is a natural evolutionary step. EVG’s low-temperature debonding technology and our ZoneBOND Open Platform approach enable a standardisation of processes and equipment, which provides customers with a wide choice of bonding materials for increased flexibility during thin-wafer processing,” adds Matthias.
Since its introduction in October 2011, ZoneBOND TB/DB technology has fast gained a foothold in the semiconductor industry. Companies such as Fraunhofer IZM ASSID, which has expertise in advanced semiconductor R&D, received ZoneBOND equipment for processes and materials qualification as part of a joint-development agreement with EVG.
