New Technique Visualizes Live Cells
New Technique Visualizes Live Cells A new optical imaging platform represents a significant step toward a longstanding scientific goal: visualizing small biomolecules inside living biological systems with minimum disturbance. A team at Columbia University has developed a new general method to image a broad spectrum of small biomolecules, such as molecular drugs and nucleic acids, amino acids and lipids, for where they are localized and how they function inside cells.

WHITE PAPER
DataRay Inc. - Real-time Profiling for Focusing, M2, Divergence & Alignment Real-time Profiling for Focusing, M2, Divergence & Alignment
DataRay Inc.

Beam intensity profiling is an essential tool in many aspects of photonics. The precise intensity distribution in a focused laser beam is critical in many applications: flow cytometry, laser printing, medical lasers, and cutting lasers are just a few examples. Intensity profile measurements can characterize and improve a product or process, leading to substantial cost and time savings that can pay for the measurement instrument many times over. This white paper describes how the unique, patented, real-time multiple z-plane XYZTF capabilities of the BeamMap2 slit-scan profiler can speed and simplify laser assembly alignment.
