Windows and Prisms Case Studies and White Papers

  1. Design of Uniform Window Heating Structures for Electro-Optical Systems

    This white paper is on the use of electrical heating techniques on a window’s surface and the temperature uniformity that the window experiences as a result.

  2. An Introduction To Digital Microscopy Imaging

    As fun as taking pictures may be, it is the professional analysis of samples that really counts. This article discusses key concepts of digital microscopy imaging systems and how these concepts contribute to a professional presentation of your work. By SPOT Imaging Solutions, a division of Diagnostic Instruments, Inc.

  3. Understanding Optical Coatings For Military Applications

    Virtually all optical components used in military applications, such as target designation, rangefinding and IR countermeasures, employ thin film coatings to somehow modify their transmission and reflection characteristics. Yet, despite their ubiquity, many military system designers are not familiar with the commonly encountered tradeoffs in thin film design, or with the characteristics of various coating deposition technologies. As a result, optical coatings are often specified in ways that drive up cost unnecessarily. This article reviews some of the most important design and deposition factors. It is intended to help those who specify optical coatings establish a realistic set of specifications that deliver the necessary performance in the most cost-effective manner.  By Trey Turner, Chief Technology Officer, REO

  4. Pulse Compression For Ultrafast Nonlinear Microscopy

    It has been established that optical techniques based on nonlinear processes, such as two‐photon excited fluorescence (TPEF) and second harmonic generation (SHG), are advantageous for microscopic imaging at depth [1‐4]. When compared with confocal or wide‐field microscopy techniques, they provide greater penetration depths and superior image contrast. The nonlinear optical response to a focused laser field is intrinsically confined to the focal volume, which helps mitigating light scattering effects and allows imaging at depths as large as four‐five mean free path lengths [5‐7].

  7. White Paper: Non-Invasive Biomedical Imaging With FD-OCT
    Current medical practice poses a constant demand for development of non-contact, minimally invasive imaging techniques that can be used in clinics and hospitals for early diagnostics of various diseases and as an alternative to standard excisional biopsy. Optical coherence tomography (OCT) is a relatively novel imaging method that allows for non-invasive, cross-sectional imaging of the biological tissue structure with cellular level resolution and at depths of up to 1.5–2 mm below the surface.
