Medical Lasers Cut and Heal
For medical lasers, the future may include both addition and subtraction. That’s because in medicine, lasers have traditionally been used for ablation, cutting and other processes that remove tissue. Now researchers and companies are looking into harnessing the power of light to stimulate a bioresponse, thereby triggering growth and ushering in an additive approach.

Fluorescence Imaging Enters the Surgical Suite
In the last decade, researchers have worked extensively on medical devices and applications that measure the spectral response of tissue to various wavelengths of light. These applications, in a lab or proof-of-principle setup, have proven the usefulness of spectral imaging to strengthen diagnosis by uncovering information hidden in the spectral signature.

fNIRS Tool Measures Brain’s Response to Acute Pain
Functional near-infrared spectroscopy (fNIRS) — an optical imaging tool for monitoring regional blood flow and tissue oxygenation — is being explored as an option to track the brain's response to acute pain in adults and infants. The fNIRS technique is portable and noninvasive, which is an advantage over other hemodynamic-based imaging techniques. It also does not require ionizing radiation or drug injection and can withstand a certain amount of motion.

Light Sheet Microscopy (oSPIM)
Applied Scientific Instrumentation Inc.
ASI’s Oblique Single Illumination Microscope (oSPIM) is an excellent platform for high resolution light sheet microscopy for samples mounted in standard coverslip-bottom culture dishes. The oSPIM is a single-view light sheet system where the illumination light sheet is generated at an oblique angle using an oil immersion objective below the sample dish.

Combine 4 Light Sources Into a Single Beam
SUTTER INSTRUMENT
Scientists have long requested a light source with sub millisecond switching accuracy powerful enough for fast imaging in order to accomplish their most demanding experimental protocols such as optogenetic stimulation. The Lambda 421 answers this request with integrated high power LEDs and a unique, efficient and flexible way of combining the individual beams for unprecedented high switching speed and high power light performance through a reflective pentagon based beam combiner.
