  1. Thin-Film Optical Components For Use In Non-Linear Optical Systems
    11/16/2017

    Bio-imaging and detection techniques that use non-linear optical (NLO) phenomena have led to great advancements, such as super-resolution images, label-free visualization of naturally occurring biomolecules, and greater freedom for working with in-vivo samples. Many NLO systems rely on the high peak pulse intensity of femtosecond lasers for signal generation, and demand that optical filters and mirrors integrated into these systems have an appropriate laser damage rating, and the reflective components be controlled for both group delay dispersion (GDD) and flatness. This white paper discusses the importance of choosing thin-film optical components for NLO systems to ensure optimal signal strength, resolution, and image quality.

    LIDAR is now being used for obstacle avoidance in autonomous vehicles, urban planning, security, infrastructure development, and many other growing applications. This application note details how high-performance, ultra-narrowband interference filters improve LIDAR signal-to-noise ratios in specific applications.

  3. Understanding Interference Tilted Excitation (LITE) Microscopy
    11/15/2017

    When the detection of a cellular or subcellular structure requires a high NA detection objective for the superior resolution and light collection efficiency, conventional fluorescence microscopy and Light Sheet Fluorescence Microscopy (LSFM) encounter challenges. Imaging these structures is difficult and could only be achieved through multi-view SPIM geometries with a 1.2 NA objective and subsequent deconvolution – an incredibly time consuming and data heavy process. Lateral Interference Tilted Excitation (LITE) microscopy overcomes this problem by eliminating the illumination objective and introducing a tilted light sheet through a photomask and cylindrical lens that can converge at the working distance of high NA objectives.

  4. Understanding Spinning Disk Confocal Microscopy
    11/15/2017

    Using conventional fluorescence microscopy for biological imaging can be challenging because this technique does not construct 3-D images needed for 3-D specimens, and it is not able to gaze past cell features to view what happens inside certain biological structures. Confocal microscopy uses optical sectioning to obtain multiple, thin, 2-demensional slices of a sample to construct 3-D models. This enables studying 3-D structures with fast dynamic processes, long-term time-lapses, or details inside the cell membrane, all possible with live cells.

  5. Understanding Light Sheet Microscopy
    11/15/2017

    Microscopy technologies are continuously striving to exploit new boundaries by aiming for smaller details, and becoming more sensitive and less noisy. Light sheet microscopy, first discovered by Richard Zsigmondy and Henry Siedentopf in 1903, is a technique that images a mostly large sample with short time intervals under healthier conditions over a longer period of time than conventional types of microscopy. This white paper introduces the technology in brief, walks through sample preparation for the technique, and describes its advantages and drawbacks.

  6. Understanding Oblique Single Plane Illumination Microscopy (oSPIM)
    11/14/2017

    Oblique Single Plane Illumination Microscopy (oSPIM) is a platform for high resolution light sheet microscopy that combines the low photo-bleaching and photo-damage of LSFM with high magnification, high NA objectives for cellular and subcellular imaging. This paper describes how oSPIM works, its advantages over conventional fluorescence microscopy, and the equipment required for this technique.

  10. Benchtop Thermal Imaging: A Simple-To-Use, Cost-Effective Solution For Troubleshooting Complex Printed Circuit Boards
    11/2/2017

    Electronic products used in aerospace applications and for scientific research have two key requirements: they must have both the high performance and the reliability to withstand intense environments. To attain that performance, electronics designers often use small parts and routinely push them to their limits. But that means the parts get hot. If they get too hot, they can’t be counted on to work reliably. Sometimes, they even break.
