  1. UV to MWIR Optical Coating Broadband Measurement

    One of the truly unique features of the PHOTON RT spectrophotometer is the capability to run broadband measurements. The most sophisticated configuration offers an unsurpassed opportunity to qualify optical coatings continuously from 185nm in the UV to 5200 nm in the MWIR.  Throughout EssentOptics business history, they have regularly set new benchmarks for broadband measurement capability. Since their first announcement...

  2. Computer Generated Hologram (CGH)

    Complex asphere metrology ideally suited for production-level volumes. Advances in diamond turning and small-tool deterministic polishing have dramatically increased optical manufacturing capabilities to produce nearly any surface shape. Designers have leveraged these capabilities by increasingly designing aspheric optics into imaging, sensing and laser systems to improve performance and reduce size and weight of optical systems. However, it isn’t just the polishing equipment...

  3. Teflon Coated With 2nm Platinum Using Luxor Pt Sputter Coater Delivers Stunning Imaging Quality

    The synthetic fluoropolymer of tetrafluoroethylene AKA Polytetrafluoroethylene (PTFE) and its analogues are strongly hydrophobic and having low surface energies of less than 18 dyn/cm are perhaps best-known for their non-stick properties. This low surface energy along with PTFE’s high electrical insulating properties can make sputter coating with noble metals prior to SEM a real challenge. Not anymore. Image courtesy of...

  4. How Smooth is Smooth?

    This question is of interest to many manufacturers today. Why? Because more of them are making high precision, small-scale components that are critical to the function of a host of end products. A company’s livelihood may mandate that the components they use in their products are uniform, definable, and "high-precision". This is where an understanding of smoothness is helpful. So...

  5. CASE STUDY: Electric Vehicle Manufacturing and Precision Metrology

    Ford Motor Company is an American multi-national automaker that recently announced a plan to invest US$22 billion through 2025 in the electrification of their mobility products. The ChallengeIn electric vehicles (EVs), new processing methods for gears must convert the high-force torque from electric motors to the RPMs at the wheel. This much be achieved while also reaching the consumer's intended...

  7. Technical Note: With Near Field Scanners you will discover a new and powerful way to “see” EMI!

    Arturo Mediano Y.I.C. Technical Advisor - Professor University of ZaragozaAs you know from some of my previous publications, I love near field probes. They are very useful to "see" magnetic and electric fields in time domain (scope) or frequency domain (scope with FFT or spectrum analyser). When interested in electric fields, a small tip is used to capture electric field...

  8. How to Diagnose Board-Level Design Issues Using Very-Near-Field Measurements

    The EMScanner provides board-level design teams with world-leading fast magnetic very-near-field data to help diagnose EMC design challenges. The instrument captures and displays visual images of spectral and real-time spatial scan results in seconds. PCB designers can now scan any board to identify both constant and time based emission sources in the range of 150kHz to 8GHz. This report provides...

  9. Vibration Isolation for Cell Culture Incubators

    Cell culturing is a common technique used in biology to carefully grow a specific type of cell. Great care is taken to maintain sterile conditions when preparing cell cultures. They are typically prepared in a sterile, vented hood with materials that have all been disinfected before use. Cell cultures are then carefully placed in an incubator to maintain a sterile...

  10. How a desktop SEM saves lab operators a lot of time

    How a desktop SEM saves lab operators a lot of time
    Is it true that as a lab operator, you work under constant time pressure? Do you find it challenging to deliver output quickly? Does it take hard work to maintain your high standard of quality? Here we explain how a tabletop scanning electron microscope (SEM) can be used to increase your research productivity and therefore to save a lot of...
