  1. Use Low-Cost Materials To Increase Target Emissivity

    Clean, unoxidized, bare metal surfaces have such low emissivity that they are difficult to measure with a thermal imaging camera. This application note describes how to use a variety of low-cost materials to increase target emissivity in many industrial R&D and electrical applications.

  2. “Dynamic” Deadfront Interface Panel Glass

    A “dynamic” deadfront panel is used to create a sleek, uncluttered user interface appearance, drawing attention to the “hidden” light up indicators as required. The icons or other alpha-numeric indicators are visible when backlit, and when unlit, a monochromatic streamlined look is achieved. Abrisa Technologies offers complete solutions for deadfront panel glass technologies including screen printed graphics, chemical strengthening or heat tempering, anti-scratch coatings, and more.

  3. Thermal Lock-In Inspection Of Semiconductor Devices

    Thermal imaging cameras can be utilized as powerful tools for semiconductor failure analysis. This application note discusses the value and effectiveness of using thermal lock-in when conducting semiconductor inspections.

  4. How To Specify A Filter

    In general, typical filter optical specifications will include the wavelength ranges over which to reflect and transmit light, clear aperture of the filter, the polarization state of light for non-normal angles of incidence, light coherency (laser or white light), optical beam size and cone angle of light, and more. 

  5. Drones Will Change The World

    For autonomous flight, UAVs must independently detect obstacles and avoid them, monitoring their surroundings with LiDAR systems. This white paper discusses how the future of drones and UAV technologies will change the world we live in.

  6. Highest Quality Laser Interferometer Measurements Require Highest Quality Reference Optics

    Fizeau interferometers are used to measure the shape and quality of optical surfaces with high precision by comparing the optic under test to a reference optic. However, it is important to remember that not all reference optics are created equal, as design and construction may cause quality fluctuation. 

  7. Machine Vision Tools Enhances 2D And 3D Surface Metrology And Inspection

    In metrology and process control, vision software must be able to identify all dimensions presented and have the ability to auto adjust the alignment accordingly. ZYGO recognized that and sought to make the process simpler for all involved. 

  8. Reliable And Precise Measurement Of Optics In Production Environments - The Fast And Easy Way!

    There are many solutions available that attempt to correct a poor environment in order to mitigate its undesirable effects. A typical solution is to use a vibration isolation table, and sometimes facilities are completely renovated in order to establish a "metrology" grade environment. 

  9. When The Driver Becomes The Passenger: Why Lighting Is Key For The “Car Of The Future”

    The “car of the future” isn’t about driving, but relaxing. Driverless cars will employ functional and accent lighting that allows passengers to just enjoy the ride. Installed smart systems that can imitate natural light will adjust their color and warmth automatically, depending on the time of day.

  10. 3 Technology Trends Shaped By Glass

    Often times, the “next big thing” is propelled forward by the components that make it possible. In this article, the discussion will be on how glass is setting trends as the component unlocking the imagination of designers and engineers around the world. Download the full article for three trends in technology that are being shaped by glass.
