Does GFP have high quantum efficiency?

victoria has a major excitation peak at a wavelength of 395 nm and a minor one at 475 nm. Its emission peak is at 509 nm, which is in the lower green portion of the visible spectrum. The fluorescence quantum yield (QY) of GFP is 0.79….

What is fluorescence quantum efficiency?

The ratio of photons absorbed versus emitted as fluorescent light is referred to as the fluorescence quantum yield or quantum efficiency and is associated with the fluorescence intensity of fluorescent substances. In this article, the ratio determined by this method is referred to as fluorescence quantum efficiency.

What kind of image sensor does SiOnyx xqe use?

XQE image sensors deliver unprecedented performance advantages in infrared imaging, including sensitivity enhancements as high as 10x today’s sensor solutions. 1.3MP, SXGA, 1280×1024 pixels, 1″ optical format.

What does SiOnyx do for the US Army?

SIONYX has supported the U.S. Government (Defense and Intelligence) with advanced imaging and camera technology and recently was awarded a ~$20M contract by the U.S. Army for the delivery of digital night vision cameras for the highly publicized IVAS (Integrated Visual Augmentation System) program.

What does SiOnyx night vision do for hunters?

IT ALLOWS HUNTERS TO FILM IN CONDITIONS THAT WERE PREVIOUSLY IMPOSSIBLE TO FILM IN. SIONYX HAS TOTALLY CHANGED THE WAY I NAVIGATE AT NIGHT. IT GIVES ME FULL CONFIDENCE. I NEVER THOUGHT THAT WE WOULD HAVE GREAT QUALITY NIGHT VISION CAPABILITIES WITH OUR SMALL DEPARTMENT. I CAN SEE CLEARLY NOW THE NIGHT IS HERE.

How does quantum yield relate to the effic?

The quantum yield relates the effic … Fluorescent proteins are commonly used in cell biology to assess where proteins are within a cell as a function of time and provide insight into intracellular protein function. However, the usefulness of a fluorescent protein depends directly on the quantum yield.
