  1. Optical Monitoring System Improves Thin-Film Coating Accuracy

    Many challenges are associated with enabling greater accuracies in optical thin-film coatings. In the past, a thin-film design software was used to help develop the coating, but the real challenge was in actually replicating the design thickness and the material indexes inside the coating chamber, without any errors. Precision Glass & Optics (PG&O) offers a real-time optical monitoring system – the IDEM system – that can calculate the thickness of each layer to within 1 nm of the design thickness, and show what the index dispersion is during the coating process, so that any concerns may be immediately dealt with in the design process.

  2. Rethinking Car Interior Design For The Living Room On Wheels

    Car companies and designers are dreaming big, imagining interiors that will radically transform how people experience driving. If the “living room on wheels” is going to be shared, the components – from the screens we watch to the touch panels we use to choose the program – will need to be easy to clean, durable, and stylish. Glass can make these dreams a reality.

  3. Imaging Through Atmospheric Obscurants

    The Salt Lake City Valley in Utah sometimes experiences trapped air pollution in the atmosphere for an extended period of time, which severely reduces ground visibility. This article demonstrates the difference between using visible light and SWIR cameras to provide greater detail in imaging, even in the most challenging conditions.

  4. Introduction To Silicon Photomultipliers (SiPMs)

    Silicon Photomultipliers (SiPMs) are radiation detectors designed with extremely high sensitivity, high efficiency, and very low time jitter. The technology is based on reversed biased p/n diodes, making them capable of direct light detection ranging from near ultra violet to near infrared. 

  5. Miniaturize Your Optical System Into A Photonic Integrated Circuit

    Embedding photonic functionalities into an integrated optical chip can often simplify and reduce the size of a system. This white paper introduces the basic concepts of photonic integration with a goal to help the reader understand how it can improve optical systems.

  6. Thermal Imaging In Advanced Driver Assist Systems (ADAS)

    The introduction of Advanced Driver Assist Systems (ADAS) will transform how humans travel and transport goods by road. There are many types of sensors used in ADAS environments, and thermal imaging is used to benefit identifying objects, even in challenging lighting conditions. This application note covers the use and benefits of thermal imaging technologies within ADAS.

  7. The Smart Buyer’s Guide To Choosing The Right PTU

    Many times, system integrators and camera system designers are asked to add pan/tilt capabilities to an existing sensor. There many factors to consider with this challenge, especially since this addition can have a large impact on the system cost, reliability, and performance. 

  8. Emerging Applications For Miniature Thermal Imaging Cameras

    More people are becoming aware of the uses of thermal imaging, especially in the cases where the technology has saved lives. This article presents many different emerging applications for miniature thermal imaging cameras and the advantages that they can provide.

  9. BMW Incorporates Thermal Imaging Cameras In Its Cars

    BMW has integrated night vision systems in order to detect living objects that are not illuminated in total darkness.

  10. Flourescence Imaging Via Microscope

    This article explores the use of a SnapShot imager in fluorescence imaging via microscope for the very first time. The imager is both compact and attachable via C-mount to any commercially available light microscope.
