  1. How A Tiny Fiber Can Prevent A Large Explosion

    For flame and spark detection, fiber optics offer an electric-free, safe, flexible, customizable, and efficient way to transfer light from any position to a sensor kept away from hazardous environments.

  2. How To Measure Thin, Parallel Optics

    Thin, parallel optics are difficult to measure, because both front and back surfaces reflect light. Fourier- Transform Phase Shifting Interferometry can separate those reflections and provide more information than traditional methods. 

  3. Nano-Positioner Manufacturer Chooses ZYGO DMI System To Characterize Performance

    This article tells the story of how Physik Instrumente (PI), a premier supplier of nano-positioners, needed to characterize and quantify the performance of their PICMAWalk positioner, and used ZYGO's ZMI™ Displacement Measuring Interferometer  to demonstrate their PICMAWalk positioner's capability to reliably and repeatably move in 0.5 nm steps using closed-loop control.

  4. Lasers Easily Make Tough Measurements In Automobile And Aircraft Manufacturing

    Lasers and laser line modules offer measurement capabilities that can catch misalignment, reduce time in finding problems with production, and make gap measurements in a large variety of automobile and aircraft manufacturing applications.

  5. Navigating From Additive Manufacturing To Injection Molding

    Engineers, designers, and product developers have found these two processes work well together in the product lifecycle, starting with the design-risk mitigation of 3D printing prototyping and then shifting to the manufacturing method of injection molding for higher volumes.

  6. Part Marking Using Pad Printing And Laser Engraving

    When designing parts for injection molding, you may need to consider finishing options, which can help improve a part’s mechanical properties, enhance surface finishes, facilitate the final assembly process, or just further customize your part or parts.

  7. Thermal Stereo Vision Makes Safer Cars

    Not only could the thermal stereo camera theoretically tell the vehicle’s computer system to slow down upon detecting an object in the road in any lighting condition, it could also provide redundant distance data, along with the vehicle’s visible camera and radar systems, to ensure the vehicle makes the most appropriate decision for the circumstance.

  8. Mastering The View Into Tricky Environments: Find Your Answer In Fiber Optics

    Glass imaging fiber optics offer a versatile way to see into hazardous environments, allowing cameras to be kept in safe places or providing an all-optical backup view that doesn’t require power.

  9. PEEK, PEI, LSR, And Other Material Options For Medical Prototyping

    Developing medical device parts is a high-stakes process, and material choice is an important decision. Five strong contenders include PEEK, PEI, and PPSU; polycarbonates; medical-grade liquid silicone rubber; and 3D-printed titanium and ABS-like WaterShed XC 11122. 

  10. Why ADAS And Autonomous Vehicles Need Thermal Infrared Cameras

    Safe advanced driver assist system (ADAS) vehicles and autonomous vehicles (AV) require sensors to deliver scene data adequate for the detection and classification algorithms to autonomously navigate under all conditions.
