Detecting Single Proteins By Their Shadows

For some time the field of optical sensing has been dominated by fluorescent marker methods. By eliminating these markers, however, a new method from the Max Planck Institute for the Science of Light might significantly advance this field of research.

    Optical Imaging Through Opaque Layers

    If you were to shine a light on someone’s skin, you wouldn’t expect to see what’s going on behind it. With a new technique published in The Optical Society’s journal Optica, however, you can do just that with surprisingly high levels of resolution.

    Introduction To Fiber Laser Marking

    While laser marking systems employ exactly the same principle as burning leaves with a magnifying glass, the process is slightly more complicated. Instead of sunlight being passed through a simple lens, laser light is passed through a more complex lens — an f theta lens. And, while sunlight consists of many colors or wavelengths, laser light has the property of being monochromatic. This article provides an introduction to fiber laser marking and explains the three most important settings that can affect how a part is marked.

Low Temperature Shift IR Bandpass Filters

Low Temperature Shift Infrared (IR) Bandpass Filters from Deposition Sciences, Inc. (DSI), manufacturer of highly durable thin film optical coatings, are ideal for critical applications that require minimal fluctuation in center wavelength (CWL). Infrared coatings experience a shift in spectral placement with changes in temperature but DSI’s “Low Temperature Shift” IR coatings shift approximately half the amount of “Standard” IR coatings. Filter characteristics, such as bandwidth, center wavelength, slopes, blocking level, and more, can be customized depending upon application requirements. The new infrared coatings are ideal in environments where it is impractical to actively heat or cool to maintain temperature stability, for example analytical instruments used for anesthesia monitoring, gas-sensing, and chemical analysis.

    4 Electronic Design Requirements Of The System-Integrated Soldier

    Perhaps most famously portrayed in Robert Heinlein’s Starship Troopers (1959), the idea of the “future soldier” has been around for decades. As rehashed in countless science fiction films and video games, the stereotypical future soldier is equipped with a protective exoskeleton, enhanced sensory equipment, seamless communication systems, and advanced weaponry. While the concept once seemed implausible, there are many real-world projects under way focused on realizing those seemingly fictitious warfighter capabilities — by integrating a plethora of diverse electronic subsystems into a cohesively operational suit.

  • Key Issues Of Optical Thin Film Coating Fabrication

    Before an optical thin film coating can be fabricated, a coating design is needed that will meet the requirements. Before the design can be finalized, it is necessary to know the n- and k-indices of refraction of the materials to be used. Before the indices can be known, it is necessary to have deposition processes, perform test coatings, and measure and characterize the n- and k-values of the materials to be used in the coating.  The deposition processes also require the proper equipment.

  • Rolling Shutter Vs. Global Shutter

    Two image sensor types widely used in cameras for microscopy are scientific grade Charge Coupled Devices (CCD) and scientific Complementary Metal Oxide Semiconductors (CMOS or sCMOS). There is a number of similarities between the two technologies, but one major distinction is the way each sensor reads the signal accumulated at a given pixel. This technical article explains how the differences in readout modes impact the exposure timing, illumination, and triggering of cameras and light sources in microscopy experiments.

  • Introduction To Fiber Laser Marking

    While laser marking systems employ exactly the same principle as burning leaves with a magnifying glass, the process is slightly more complicated. Instead of sunlight being passed through a simple lens, laser light is passed through a more complex lens — an f theta lens.

  • Camera Requirements For 3D Metrology

    As the objects to inspect/measure in high-tech manufacturing become smaller, higher-resolution cameras with better spatial resolution can improve accuracy and precision. This does require a high-quality machine vision camera design, however, or what is now called a metrology camera. 3D measurements in particular pose increasing demands on camera performance and reliability. This article discusses critical parameters, depending on the specific measurement.
