What is the reflector?
The reflector, also referred to as a spectrophotometer, is an optical tool used to measure light intensity with a solution or object as a wavelength function of the light. They are usually used to measure how discouraging a specific solution, glass object or gas. Reflectors also measure light diffusion for each of the known wavelength range. The spectrometer produces the light of any wavelength and the photometer records the light intensity. For the use of the device, the test subject is placed between the ray of the spectrometer and the photometer. The light intensity is absorbed by a photometer, which then sends a voltage signal to the gavometer, used to display scientific results. As the amount of light changes is changed by the solution, the voltage signal changes to find the proportional relationship between the concentration of the dissolved substance and the intensity of the light from the spectrometer. The intensity of the transmitted light through a mixed solution, ie one with a color dissolved substance, equals the intensity of the transmitted SVItems with a clean solvent, multiplied by ten to negative power of mixed solution, times constant, and the distance that light passes through the solution. This relative equation is commonly known as the beer law, an important principle in the area of spectrophotometry and light absorbance.
In industrial and teaching laboratories, many different types of reflectors are used. One type of reflectometer, often used in the academic environment, is called the Spectronic ™ 20 or Spectrofotometer Spectronic ™ 20. The desired wavelength is also set. Special tools such as curvature must be used to accurately analyze the light sample.
Once the wavelength is set, the reflectometer is to zero to ensure the most accurate spectrophotometric results. Then the tube is erased clean andThe sample is placed in the tube. The light control knob is on the absorbance scale to zero. Before performing tests on required solutions, scientists usually perform tests for reference solutions to provide a scale for future results. After testing the reference solution, recalibration can be carried out and real tests can begin.
