Microscope Could Speed Up and Simplify Breast Cancer Treatment

Researchers have developed an ultra-tiny endo-microscope that could help improve breast cancer treatment and cut NHS waiting lists.

Designing Lenses for Near-Infrared and Fluorescence Endoscopy

Fluorescence endoscopy is becoming increasingly important in many medical diagnostic tests. Based on the molecular absorption of light, this technique works by revealing...

Lens Offers Tunable Focus

A metasurface lens has been created that uses a piezoelectric thin film to change focal length when a small voltage is applied. Because it is extremely compact and lightweight, the new lens could be useful for...

Smart Lens Prevents Diabetic Retinopathy

Researchers have developed a smart contact lens-type wearable device to prevent diabetic retinopathy and treat it in its early stages by irradiating 120 μW far red/LED light to the retina. This...

Optical Design Considerations for Additive Manufacturing

Light-based methods open many opportunities for medical applications.

Product Focus: Test & Measurement

Trackers, interferometers, laser sensors, and more.

Optical Lens Design Considerations for Cell Imaging in Microscopy

Understanding application, use case, and image resolution are key.

Tiny Package, Big Resolution: Wafer-Level Camera Reaches Smallest Parts of Anatomy

A new camera module with quadruple the resolution of its predecessor, at 400 × 400, or 160 Kpixels, provides clear images inside the body’s farthest...

Tool Improves Imaging of Brain Activity

Researchers from UNC-Chapel Hill and NC State University developed a new technology that will allow neuroscientists to capture images of the brain almost 10 times larger than previously possible...
