New Test and Laboratory Controller for LED Lighting

LATAB, the Swedish manufacturer of LED lighting and controllers for machine vision applications is proud to introduce a new multifunction controller which will be presented at "Vision", the international trade fair for image processing from 8-10 November in Stuttgart.

The controller has been specially developed for test and laboratory applications. It enables users the ability to optimize the LED lighting for an application very quickly. Simply use one of the two continuously variable adjustment buttons/knobs on the controller to find the optimum lighting conditions for your application and you are up and running. The system can be used in “continuous lighting” mode or “strobe” mode. In continuous mode the controller can drive LED’s at current ratings of up to 3 amperes. The brightness can be continuously adjusted using the control dial.

Using a variation of the continuous mode called “switched” mode the LED’s can be driven at increased brightness for a maximum of 5 seconds. The illumination in this mode can be twice as bright as in standard continuous mode without overloading the LEDs.

In strobe mode, the LEDs can be driven at up to 24 amperes current. The flash brightness can reach up to five times the value of that in continuous mode and can be continuously adjusted as can the frequency up to a maximum of 200 Hertz. The flash duration range is from one microsecond up to five milliseconds. It can be triggered either by an internal frequency generator, an external synchronization source or manually on the controller.

This controller can also operate LED lights made by other manufacturers.

LATAB offers a comprehensive range of standard LED controllers and lights, LATAB is also able to offer standard products modified to customer requirements and completely new customized solutions. This ability highlights LATAB’s expertise in the field of providing individual solutions to image processing applications.

The Metricon 2010/M Prism Coupler’s key ability is to rapidly and accurately measure both the thickness and the refractive index/birefringence of dielectric and polymer films. The Model 2010/M offers unique advantages over conventional instruments based on ellipsometry or spectrophotometry.

For thin films in the range of 0.5 microns to >15 microns:

• It has a routine index accuracy of ±.0005, resolution of ±.0003 (accuracy of up to ±.0001, resolution ±.00005 achievable for many applications)
• It is completely general - no advance knowledge of thickness, index, or material type required
• It is applicable to a wide range of application areas - measures thin films on higher or lower index substrates, free standing flexible polymer films, waveguides, Surface Plasmon Resonance (SPR) structures
• It can provide rapid characterization of thin film or diffused optical waveguides including waveguide loss

For bulk materials and now liquids, using the new Liquid Cell Option:

• It can provide high accuracy determination of dispersion (index vs wavelength) and measure Abbe number.
• It can measure refractive index/birefringence measurement of bulk materials, including flexible polymers and now liquids.

The new Glacier™ X from B&W Tek Inc. is the smallest TE cooled spectrometer on the market, making it the perfect solution for applications requiring high performance and portability. It is equipped with a 2048 element linear CCD array, built-in 16-bit digitizer, and high-speed USB 2.0 interface.

Compared to non-cooled CCD spectrometers, the Glacier™ X offers higher dynamic range, significantly reduced dark counts, and superior baseline stability, making it ideal for low light level detection and long-term monitoring applications.

Wavelength configurations are available from as low as 200nm to as high as 1050nm with resolutions between 0.6nm and 4.0nm. Flexible custom configurations and application support are also available for OEM customers.

TE cooling makes it possible for weak signals, such as fluorescence and Raman, to be integrated for sufficient time to accumulate measurable signals for detection, resulting in a far superior signal-to-noise ratio. Glacier™ X therefore gives customers the ability to make low light level spectroscopic measurements without the need for larger, more expensive spectrometer systems.

The combination of temperature cooling and regulation, together with a compact form factor also make Glacier™ X a perfect choice for OEM system integrators.
