UV-VIS Spectrophotometer with 4nm Bandwidth

A spectrophotometer is a commonly used laboratory instrument that measures the ability of a substance to absorb, transmit, or reflect light at different wavelengths. It determines the concentration or optical properties of the sample through the absorption degree of the light emitted by the light source. The spectrophotometer is widely used in chemistry, biology, environmental science and other fields, and is an important tool for quantitative analysis, quality control and research.

Instrument structure introduction
The working principle of a spectrophotometer is based on the Bier-Lambert law, which states that the absorption of light is proportional to the concentration of the sample.

It usually consists of the following main components: Light source: Spectrophotometers usually use visible or ultraviolet light sources, such as incandescent, halogen or deuterium lamps. The light emitted by the light source passes through the selection device to select a specific wavelength of light. Monochromator: A monochromator is used to select and adjust the desired wavelength. It can be a prism or grating structure that separates multiple wavelengths of light by the principle of dispersion and selects a specific wavelength sample chamber: the sample chamber is the area where the sample to be measured is placed. The sample can be a solution, gas, or solid sample. When light passes through a sample, its intensity is affected by the absorption or transmission of the sample. Photoelectric sensor: Photoelectric sensor is used to measure the intensity of light after passing through the sample. It converts light energy into an electrical signal and determines the degree of light absorption according to the size of the electrical signal. Detection system and data processing: Spectrophotometers are usually equipped with detection system and data processing functions. These functions can include light intensity measurement, wavelength calibration, data recording and analysis, etc. By selecting the appropriate wavelength, calibrating the instrument, and measuring the absorbance or transmittance of the sample, the spectrophotometer can be used to measure the concentration of the sample, reaction kinetics, solution equilibrium, spectral analysis, etc. It can also perform quantitative analyses, such as constructing a standard curve to determine the concentration of an unknown sample.
