The spectrometer from Lisun Group has a wide range of applications, for instance, agriculture, astronomy, automobiles, biotechnology, chemistry, coating, colorimetric measurement, environmental monitoring, film industry, food, gem testing, LED testing, printing, paper-making, Raman spectroscopy, semiconductor industry etc. There are some typical applications shown as below. 1.Color measurement (for detailed information please click here)—colorimeter. Generally speaking, […]
InGaAs linear imaging detector has high sensitivity in the near infrared wavelength region. An amplifier array with CMOS transistor charge, a shift register and a timing generator module are included in the detector. Two InGaAs detectors from lisungroup are available for users to choose. 256 pixels cooling InGaAs detectors can be used for the wavelength […]
There is charge stored in the charge-coupled device CCD detector, and the charge will be released when the photon irradiates to the photosensitive surface. At the end of integration time, the remaining charge will be transferred to the buffer. Then the signal is transferred to the A/D conversion card. Due to the natural integral attribute […]
The optical resolution of spectrometer is the smallest wavelength difference that the spectrometer can distinguish. To separate the two spectral lines, you have to make them image onto the two adjacent pixels on the detector at least. Because the grating determines the degree that different wavelength can be separated on the detectors (dispersion), therefore it […]
The diffraction grating is an optical component which can decompose the incident polychromatic light into monochromatic light it contains. Grating is constituted by series parallel grooves of the same width and spacing, and these grooves are carved and made on the substrate material plated with reflective film. The grating can be divided into two kinds […]
