17 Aug 2006 Deepstar is a new laser diode system from Omicron with a modulation depth of greater than 100 000:1, at wavelengths from UV to near IR The laser specialist Omicron has manufactured a new system called "Deepstar" with specifications which are unrivalled by any other manufacturer. Deepstar is targetted at applications such as fluorescence imaging, where residual light in the laser "off" state under modulation could be misinterpretted as a signal from the sample under test. A true zero off state is particularly difficult to achieve under very high modulation rates, but by employing innovative temperature-stabilisation, this is achieved at greater than 100 MHz.
The analog and digitally-modulated laser diode module Deepstar offers a modulation depth of significantly more than 100,000 to one under either digital or analogue modulation.
Deepstar is the ideal light source, for example for Confocal Laser Scanning Microscopy and Flow Cytometry. With an ultra-deep analog modulation greater than ten megahertz and a digital modulation greater than 100 megahertz, and a signal rise and signal fall
time of less than two nanoseconds, Deepstar is also suitable for high performance applications which, up to now, were only possible using CW lasers and AO modulators. The Deepstar diode laser is available with output powers of 20 milliwatt (mW) at 375 nanometers (nm), 60 mW at 405 nm, 50 mW at 442 nm, 20 mW at 473 nm, and near infrared versions are also available. The laser's controller is equipped with an RS-232 interface and is operated with 24 volt DC voltage. Omicron can adapt the analog and the digital signal input to accept a wide range of configurations, making the laser system simple to integrate into existing systems.
Photon Lines will be exhibiting at Photonex, Stoneleigh from October 18th and 19th, on stand D02 |
