Key Takeaways: Super High Durability optical coatings (SHD Optical Coatings) enhance IR window performance with high transmission efficiency, scratch and chemical resistance, anti-reflective properties, and environmental resilience. Designed for aerospace, military, and industrial applications, SHD coatings maintain signal clarity in harsh environments, resist abrasion and chemical exposure, and withstand temperature fluctuations. Compared to conventional coatings, […]
Key Takeaways: Hot and cold mirrors are dielectric-coated optics that selectively reflect or transmit infrared (IR) radiation, offering valuable heat management solutions. Hot mirrors reflect up to 90% of near-IR (NIR) and IR light while transmitting UV and visible light. Conversely, cold mirrors reflect UV and visible light, transmitting up to 80% of NIR and […]
Key Takeaways Optical prisms are versatile glass components used to manipulate light in various applications, from laser alignment to microscopy. This optical prism selection guide outlines key prism geometries, such as right-angle, roof, and equilateral prisms, and their primary functions, including deviation, inversion, and dispersion. It highlights applications in fields like spectroscopy, medical imaging, and […]
Key Takeaways Ultra broadband metallic mirrors provide high reflectivity over a wide wavelength range (UV to NIR), outperforming standard metallic mirrors that only reflect well within narrower ranges. These mirrors are ideal for multi-purpose systems, offering flexibility, durability, and high damage thresholds. They perform consistently across various angles of incidence and are suited for applications […]
Increasing the numerical aperture of an optical system may increase the resolving power, but it’s not a foolproof way to improve performance.
Key Takeaways: The paraxial approximation simplifies optical calculations by assuming small angular deviations, useful for systems like lasers and optical fibers. It’s accurate for angles under 10 degrees, where errors are less than 0.5%, but fails at larger angles, requiring more precise methods. For waveguides with small effective mode areas or strong focusing systems, the […]
KeyTakeaways: Optical medical imaging is transforming diagnostics, surgery, and research. Diffusive optical imaging (DOI) uses NIR spectroscopy to study soft tissue, while ballistic optical imaging detects unscattered photons for high-resolution imaging, offering better optical quality than MRI or ultrasound. Photoacoustic imaging combines optical and ultrasonic methods for deep, detailed scans. Positron emission tomography (PET) tracks […]
