A spectrophotometer is a device used in laboratories to determine what the beam of radiation or electromagnetic light is and thus identify, qualify and quantify its intensity. It also allows to determine its efficiency, sensitivity, resolution and spectral range. This will depend on the variability of the design and the choice of optical components it contains.
Its operation is based on the light of the special lamp it has, which is guided by a connector that selects and separates the light from the wavelength, and then passes through a sample. The intensity of the light coming out of that sample is captured and compared with the intensity of the light that affects that sample, with this information the transmittance can be calculated, which will depend on the concentration of the substance.
The light is transported from the sample to the detector, so a reference is needed to perform the analysis. Spectrophotometers are widely used in biomedical sciences and life sciences research, including university and industrial research. Typical uses of the spectrophotometer are measurements of the density of nucleic acids, proteins and bacteria.
However, spectrophotometers are also widely used in various industries, such as biotechnology, diagnostic and clinical testing, drug research, pharmaceutical research, chemical engineering, materials science and agricultural research.
Light travels through two paths into the compartments, each with its own detector. One goes to the sample and the other to the reference. These devices have the ability to project a monochromatic light beam through a sample and measure the amount of brightness absorbed by that sample. As a result, the spectrophotometer can provide us with information on the nature of the substance in the sample, as well as indirectly indicate how much of the substance we are interested in will be present in the sample.
Some of the essential components of the spectrophotometer are, for example, the light source which illuminates a given sample and which must respond to a number of conditions such as, for example, directionability, stability, continuous spectral energy distribution. Typically used sources are the tungsten lamp or the xenon arc lamp.

Spectrophotometry is a scientific technique that focuses on the measurement of light. This technique allows scientists to obtain detailed information about the contents of certain substances, taking into account how the difference-frequency radiation is spread through the materials.
High accruacy spectrophotometer is used for accurate analysis and transmission of laboratory color.Apply in paints, inks, textiles, garments, printing and dyeing, printing etc industries for color transfer and quality control, also for Fluorescence sample color measurement.
It is used to measure the brightness factor and color coordinates of traffic signs, markings and reflective films. It contains GB 2893 and GB/T 18833 standard colors. It can customize the rectangular tolerance of polygons manually.
