Photometers and spectrophotometers instruments are well-suited and well-established for measuring moisture, oil/fat, and other easily distinguishable parameters in a wide range of applications. spectrophotometer derived from these photometers. Photometers are usually used to measure parameters at certain wavelengths where the parameter absorbs light, such as 1.94 microns for water and 1.72 micron...
Radiometry professionals may be familiar with the theories of light and color measurement; the equipment used to detect light and color. The instrument for such calculations includes radiometer, spectrometer and spectroradiometer. However, all three devices can measure light and energy. Therefore, the capabilities, intended uses, and applications of radiometers, spectrometers and spectroradiometer...
LISUN will irregularly update the software of LPCE-2（LMS-9000）Spectroradiometer & Integrating Sphere Test System. However, since each spectroradiometer LMS-9000 in the system has its own independent hardware data file, we need to back up the hardware data file before updating the software (The step 2 below). The software cannot be installed without the LMS-9000 hardware data file, and the ...
Ultraviolet rays are rays of sunlight with a wavelength of 100 to 400 nanometers (nm). English is ultraviolet, ultra- means above, beyond. The frequency of ultraviolet rays in the solar spectrum is higher than that of visible rays. Can be divided into UVA (ultraviolet A, wavelength 320-400 nm, long wave), UVB (wavelength 280-320 nm, medium wave), UVC (wavelength 100-280 nm, short wave). Among them...
Ultraviolet lamps are a type of light source that can produce ultraviolet light with a large effective range. In fact, there are also ultraviolet rays in more general light sources, and the sun is the most prominent. As for the general tungsten lamp, there is also near ultraviolet light of about 320nm in the possible range of ultraviolet transmission of glass, and it can be farther if a quartz bul...
If you need to disable the 64bit digital signature enforcement of the computer, follow the steps: For Win 7 system There are two ways and you can use any of them. Restart the computer and press “F8” at the beginning. Then you can enter “Advanced boot options”. Move the cursor to “Disable Driver Signature Enforcement” and press “Enter”. F...
As we known that the quality of LED products depend on lumen, lumen efficiency temperature and CRI etc parameters, the general test device is application with spectroradiometer & integrating sphere system to measuring electrical, photometric and colorimetric parameters. This system mainly testing lumen, CCT, CRI, spectrum, SDCM, voltage, current, power and power factor etc. As general test dev...
When choosing the instrument to purchase or use for the application, it is very important to understand the types of instruments available for measuring color. A colorimeter or spectrophotometer can be used to measure any test substance that is itself colored or can be reacted to produce a color. Both colorimeter and spectrophotometer provide data obtained over the same range of visible wavele...
