Understanding Ultra Broadband Metallic Mirrors

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 […]

Understanding the Paraxial Approximation

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 […]

Optical Medical Imaging

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 […]
