Brand New Logo & site design!!
We have a Brand New Logo, and therefore we redesigned our site.
We hope your experience with our new design will be even better then before. However if you do find any difficulties or things you would like us to improve please let us know by contacting us.
We would like to clarify that this is the same site as before and we are here to serve your demands, as we always were.
You may have noticed that now we have a Group Logo for:

The high speed lasers are advancing research in time-resolved combustion diagnostics. This application note describes the ultra-high speed, time-resolved spontaneous Raman scattering (SRS) spectroscopy technique developed by Dr. Jun Kojima of the Ohio Aerospace Institute / NASA Glenn using the PI-MAX4: 512EM emICCD camera and special 10 KHz continuous spectrum capture capability using latest version of LightField software.
In combustion, until recently only two temporal optical gating schemes were available to increase signal-to-noise ratio (SNR) for time-resolved spontaneous Raman scattering (SRS) spectroscopy. Problematic optical background noise could be rejected either by electronic gating with an image intensifier or by using a mechanical shutter. Unfortunately, each of these traditional approaches has its shortcomings.
Image intensifiers, for example, provide excellent optical background noise rejection via <2 nsec gating capability but carry several inherent limitations, such as lesser image quality and lower dynamic range. On the other hand, while a high-speed mechanical shutter with a rotary optical chopper is able to deliver wider dynamic range without diminishing the quantum efficiency (QE) of the detection system’s CCD, its 30 Hz speed and ~10 µsec gating are not sufficient for rejecting noise and can result in transmission losses of up to 50%.
In 2010, Dr. Jun Kojima of the Ohio Aerospace Institute, working with Dr. David Fischer and Dr. Quang-Viet Nguyen Ultra-High-Speed, Time-Resolved Spontaneous Raman Scattering Spectroscopy in Combustion.

FAC300 (Fast-axis collimator) - Two years after, the skepticism is left aside!
This is a special kind of success story. Nearly two years ago, LIMO introduced its new FAC300 collimator which concentrates the fast axis of high-power laser diodes. With a focal length of 300 µm and an NA (numerical aperture: measure of the ability to concentrate a ray of light) of 0.7 for the aperture angle of its lens, the new product was well suited for use with single emitter diodes and diode laser bars that operate in the "NIR" wavelength range (near infrared range: 790 to 990 nm).
Of course, the skepticism shown for this new lens from Dortmund by many potential users at the time was not only due to the broad field of application it covered. The affordable price offered by the Dortmund-based LIMO Lissotschenko Mikrooptik GmbH for its new product also left people astounded. The reason for the amazing price was the special design (half the height at 0.5 mm) which provides a significant increase in productivity (more lenses per wafer). Dr. Oliver Homburg, Director for Advanced Optical Solutions, challenged skeptical would-be users in February of 2012, saying: "Order the free test units and determine the quality of the FAC300 lenses for yourself." Twenty months later, Dr. Homburg was happy to report: "A great deal of users were pleased with the product. As with our previous FAC units, this lens was also very well received by the market."
The success inspired the experts in Dortmund to pursue a significant expansion of the field of application: The FAC300 microlens, which was launched in 2012, is part of a standard FAC portfolio that previously included more than five FAC products featuring focal lengths between 0.29 and 1.5 mm and a standard coating of 790 to 990 nm. This lineup has now been joined by two new product lines for the red (600 to 700 nm) and infrared (1000 to 1600 nm) wavelength ranges. This means that, from now on, LIMO will offer customers the ability to order FAC lenses with standard coatings for a wide wavelength range of 600 to 1600 nm.
The expansion of the wavelength range to approx. five times its original size enables the cost-effective series production of coated lenses for any type of laser application. That spectrum now ranges from the use of lasers in materials processing, medical engineering and pump applications to laser TVs and laser projectors. Dr. Homburg notes: "Users no longer face the otherwise typical extra costs for the coating. We're also able to offer extremely quick delivery of the lenses as a standard product."

SK-Electronika's Demonstration with Tektronix's test & Measurement equipment on NIDays, December 2013. SK-Electronika's engineering team adds value of automating procedures according to customer's requirements on Tektronix MDO 4000 stand alone scope.
SK-Electronika presented, last month (December 2013) during the NIDays conference a new initiative with Tektronix test & measurement equipment. By using LabVIEW (SW), SK-Electronika was able to create an added value to the MDO4000 Oscilloscope.
The MDO 4000, winner of 13 industry awards, is an Oscilloscope with a built-in spectrum analyzer manufactured worldwide by Tektronix and distributed in Israel by Eastronics. This product can capture time-correlated analog, digital, and RF signals for a complete system view of the device under test (DUT). It offers both the time and frequency domains in a single glance. Also, it is designed to view the RF spectrum over time and monitors the changes over time or over device's state.
SK-Electronika, using LabVIEW SW, programed a computer based interface that allows automatic procedures and reports from and to the MDO4000. A list of customized test scenarios was programed on the computer with an automated command to the MDO4000. According to the customer's demands, an automatic user environment was built, that allows remote control and operation of automated processes and then after reports are arranged accordingly.

VPC's Engineering team has developed a new 150 Amp contact for high power testing requirements. The contact can be used in a 4 position iCon module or a 6 position 90 Series module - both modules have an incorporated safety interlock which requires engagement prior to powering the contacts.
