Plasma Monitoring Measurement System - PM Series
PM Series is a very useful system for plasma measurement with high sensitivity and Cooled detector. The PM series can detect plasma emission of wide spectrum and low stray light, including plasma monitoring, etching, and...
pH Sensing Measurement
Optical pH sensors comprise a pH indicator dye in a matrix applied to a patch or cuvette, which changes color in response to analytes in its environment. A spectrometer measures the colorimetric (absorbance) response. Accurate pH...
Raman measurement
Raman spectroscopy uses scattering of laser light to probe molecular structure. Of every million photons scattered, a single photon will interact with the vibrational states of a sample molecule and emit light of a different...
Transmittance Measurement
Transmittance is light incident on a sample that transmits through it. If the sample has low scatter (as with a clean, dilute solution), almost all the light not absorbed will be transmitted. Advantages of AbsorbanceCan be...
Reflectance Measurement
Reflectance is light incident on the surface of a material that is reflected at an interface. Light not reflected from the sample is absorbed, scattered or transmitted. Very smooth or shiny, mirror-like surfaces have high...
Irradiance Measurement
Irradiance is defined as the quantity of energy released at every wavelength from a luminous sample, such as an LED, a laser, or the sun. More precise intensity levels can be computed using the above...
Fluorescence Measurement
Fluorescence is the absorption and emission of light of two different frequencies. Typically, a lower wavelength of incident light is absorbed from one direction, and a higher wavelength of light is emitted in all directions....
Color Measurement
Color occurs when light is perceived by the human eye. Color reflected from, or emitted by samples can be measured using basic color meters or more robust spectral devices for more detailed analysis. Accurate color...
Absorbance Measurement
Keywords: Absorbance, Measurement, Absorbing, UV, NIRAbsorbance is a process of light interacting with matter. When light hits something that takes some of the light we talk about absorbance. The light that is absorbed is not lost; it...
