Medical Lens

Medical Imaging Lenses and Lens Design for precision medical applications.

Cone-beam Imaging Scanners


Cone-beam imaging CT (CBCT) scanners offer the advantages of being compact in size, less costly, and more portable than multidetector CT systems. Image quality, however, is often impacted by artifacts such as streaking or shading, associated with cone-beam effects and/or nonuniformity in image quality near the ends of the field-of-view [...]

Tunable Lens – Changing The Way Eyes Are Viewed


Researchers have developed the first instrument that will provide a detailed image of the entire eye. Incorporating a lens that changes optical parameters in response to electric currents, the radically new technology can produce higher quality images than currently available. Combining optical coherence tomography and an electrically actuated tunable lens [...]

Optical Tweezers


Originally called ‘single-beam gradient force trap’, optical tweezers are scientific instruments that use a highly focused laser beam to provide an attractive, or repulsive force, depending on the refractive index mismatch to physically hold and move microscopic dielectric objects similar to tweezers. Optical tweezers have been particularly successful in studying [...]

Neuroimaging And Alzheimer’s


Currently, diagnosing Alzheimer’s relies largely on documentation of any mental decline. However, when diagnosing Alzheimer’s in this way, it has already caused severe brain damage in individuals. What if we could diagnose Alzheimer’s before symptoms started? It is increasingly clear that by the time a typical AD patient comes to [...]

Atomic Force Microscope


You may have seen it on CSI: The star examines hair from a crime scene and concludes its color or texture looks like the defendant’s hair, or maybe his dog’s. Case closed. But, looks can be deceiving, as well as vague and subjective. According to Frank DelRio, and engineer at [...]

Retina Camera – No Dilation Required


It’s the part of the eye exam everyone hates: the pupil-dilating eye drops. Your eyes remain blurry for several hours afterwards, often making the process inconvenient for both patient and doctor. The reason for the dilation is to keep the iris from constricting, and is used for routine examination and [...]

The Endoscope Capsule – A Camera in a Pill


Pop this pill, and eight hours later, doctors can examine a high-resolution video of your intestines for tumors and other problems, thanks to a new spinning pill camera that captures images in 360 degrees. Developed by the Japanese RF System Lab, the Sayaka endoscope capsule entered the U.S. market in [...]

Scanning Fiber Endoscope


Strokes and heart attacks often strike without warning. However, a unique application of a medical camera, a scanning fiber endoscope (SFE), could one day help physicians know who is at risk for a cardiovascular event by providing a better view of potential problem areas. The scanning fiber endoscope (SFE) acquires [...]
