Nanoparticle System

Photonics Spectra

NanoSight Ltd.Request Info
 
NanoSight Ltd.’s new version of its NS200 nanoparticle characterization system is based on the LM20 model and uses nanoparticle tracking analysis, a particle-by-particle visualization and counting method. The company has produced an easier-to-use instrument with a high-sensitivity camera built into the housing. Features include optimized locators to facilitate positioning of the measurement cell, electronic readout of the cell test temperature and an optional blue laser to improve imaging capability. Fluorescence filters can be added when working with suitably labeled particles. The electron-multiplying CCD camera is designed with maximal speed and sensitivity. It operates at 37 full fps collected directly through a USB 2.0 interface, and the laser is triggered to reduce thermal issues with respect to the sample, restricting photobleaching during fluorescence imaging.

GLOSSARY
Brownian motion
The behavior of microscopic solid particles suspended in a fluid, first observed by botanist Robert Brown in 1827 as a continuous random motion.
camera
A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
nanoparticle
A small object that behaves as a whole unit or entity in terms of it’s transport and it’s properties, as opposed to an individual molecule which on it’s own is not considered a nanoparticle.. Nanoparticles range between 100 and 2500 nanometers in diameter.
