Camera with USB 2.0 Interface

IDS GmbH (Woburn, MA) has released the UI-2280SE, a camera with USB 2.0 interface and Sony ICX655 CCD sensor in 5 megapixel resolution (2448 × 2050 pixels). The camera achieves color depth of 12 bits per pixel, thanks to its internal field programmable gate array. As a result, it offers 16 times more accurate mapping of pixel values compared to the usual 8 bits.

Optical Manufacturing Guidelines for Medical OEMs

With careful planning, system integrators can select the optimal optics, filters, light sources, and cameras for their medical diagnostic instrumentation. Custom integration of original equipment manufacturer (OEM) products can be complex, particularly for medical device integrators that build diagnostic instruments incorporating numerous optical components. Often, objective lenses, illumination sources, and imaging detectors are assembled and custom-mounted into finished instruments. Such components must not only meet stringent performance requirements, but often have to meet established Food and Drug Administration (FDA) standards.

Organic Solar Cell Initiative

Imec (Leuven, Belgium) has announced the European FP7 project X10D, an initiative aimed at developing tandem organic solar cells with an increased conversion efficiency and lifetime. The ultimate goal of the X10D project is to introduce organic photovoltaic technologies (OPV) into the thin-film PV market.

Controlling Heat Curing Adhesive Processes Using Infrared Spot Curing

Novel infrared fibers provide precision heating and curing of glues in medical device assemblies, improving workflow and design. Adhesives are often used as the joining compound between substrates in the medical device industry. Typical applications for adhesives include tube-to-connector bonding, steel-cannula-to-hub bonding, and any other joining process. Adhesives work particularly well in the assembly of dissimilar materials where traditional solvent-welding methods are being eliminated due to workplace safety legislation and where other joining methods such as ultrasonic welding and laser welding are inadequate.

Transforming Gaussian Beams into Uniform, Rectangular Intensity Distributions

The majority of laser types in current use produce output beams with circular or elliptical crosssections, with either Gaussian or near- Gaussian intensity profiles. This Gaussian intensity distribution is acceptable, and often beneficial for many applications in which the laser beam is being focused to a small spot. However, there are also many different uses for which a uniform intensity distribution (often referred to as a “flattop”) would be more optimal. For example, in materials processing tasks, a uniform intensity distribution ensures that the entire laser illuminated area is processed evenly. It is also valuable in situations where the laser light is used essentially for illumination. This is because uniform illumination makes identical features that all appear to have the same brightness, regardless of where they are located in the illuminated field, simplifying the image processing task and increasing contrast and resolution. These same benefits apply over a wide range of other applications that can be broadly classed as “illumination,” from machine vision, through flow cytometry, inspection, and even some medical uses.
