1. Bus Bars And Optics 11/21/2019

   A bus bar is a strip of conductive material applied to the surface of a conductively coated glass, most commonly ITO (indium tin oxide) or IMITO (index matched ITO) coatings. Abrisa applies bus bars either by thin film deposition of chrome-nickel-gold or by screen printing.

2. Measurements At The Speed Of Light 6/19/2018

   Measuring the thermal signatures of rockets exploding or aircraft in flight occur at high speeds. Understanding the factors that go into making those measurements will help users determine if a camera is suited for the job.

3. Why Are There Special Interfaces For The Transmission Of Image Data? 10/16/2018

   The amount of image data that must be transferred to computers for storage and processing is continuously increasing. This paper discusses the progression of camera interfaces, and how they are continuously improved to enable reliable streaming data transfer from the camera to the computer.

4. Four Reasons Thermal Cameras Can Improve Automatic Emergency Braking And Save Lives 7/17/2019

   The Governors Highway Safety Association (GHSA) estimates 6,200 pedestrians were killed in traffic accidents in the U.S. in 2018, the highest total since 1990. The GHSA also found that, during the past 10 years, nighttime crashes accounted for more than 90 percent of the increase in pedestrian deaths.

5. Palmheld Spectroscopy Becomes A Powerful Tool For The Food Industry 2/20/2019

   All aspects of the food industry may find a need to evaluate products in a field or factory. Palmheld spectroscopy provides powerful analysis without the need for expert users.

6. Understanding Electron Multiplying Gain 5/28/2020

   Electron Multiplying CCD (EMCCD) cameras can be used to detect very weak signals, which would otherwise be lost within the noise floor of the camera. Using a conventional CCD to detect these very weak signals, usually requires both long exposure times and slow readout rates. However, EMCCD cameras can detect these same signals using much shorter exposure times and higher readout rates. This is done by applying EM gain to the signal before it reaches the output amplifier of the CCD sensor, effectively reducing the read noise of the sensor by a factor equal to the amount of gain applied.

7. Why Is Binning Different In CMOS Image Sensors Compared To CCD Image Sensors? 10/16/2018

   “Binning” is defined as the combination of the charge carrier content of two or more pixels of an image sensor to form a new so-called super pixel. This white paper discusses the reasons for the difference of “binning” in CMOS and CCD technologies and how it improves the signal-to-noise ratio.

8. LiDAR And Optical Filters – Helping Autonomous Vehicles See More Clearly 10/31/2018

   The evolution of sensing and imaging systems, combined with the desire to create safer, more efficient transportation systems, is driving the development of autonomous vehicles. LiDAR is a key technology that will eventually help carry this growth through to “Level 5” autonomy.

9. Overcoming Pitfalls When Measuring Thin, Parallel Optics 3/19/2020

   Driven by the demand for smaller and smaller consumer products and semiconductor devices, manufacturers require thin planar optics for an array of applications. This puts the responsibility on the material and optics manufacturers to ensure the surface of the glass is flat and free of material deformities which can cause distortion and affect end-use functionality. One advanced solution is Fourier-transform phase-shifting interferometry (FTPSI), which enables easy characterization of the front and back surface, optical thickness variation, and material homogeneity of thin plane parallel glass.

10. Helping Light-Based Medical Diagnostic Technologies Shine During A Pandemic 4/21/2020

    COVID-19 and other pandemics increase the need for light-based medical instruments such as airway endoscopes and in vitro diagnostic devices while also bringing a wave of innovation in these areas.
