Product Description
A spectrophotometer is a scientific instrument used to measure the intensity of light at different wavelengths in a spectrum. This device is widely employed in various fields such as chemistry, biochemistry, physics, environmental science, and biology. The fundamental principle behind a spectrophotometer is based on the interaction of light with matter, specifically the absorption or transmission of light by a sample.
Here are the basic components and functionalities of a typical spectrophotometer:
1. Light Source: Spectrophotometers have a light source that emits light across a range of wavelengths. The type of light source can vary, with common sources being tungsten lamps for the visible region and deuterium or xenon lamps for the ultraviolet region.
2. Monochromator or Grating: The monochromator or diffraction grating is responsible for separating the light into its individual wavelengths. This allows the selection of a specific wavelength for analysis.
3. Sample Holder (Cuvette): The sample to be analyzed is placed in a sample holder, often a transparent cuvette. The cuvette allows the light to pass through the sample, and the amount of light absorbed or transmitted is measured.
4. Detector: The detector captures the light that has passed through the sample. Photodiodes or photomultiplier tubes are common types of detectors used in spectrophotometers.
5. Amplifier and Readout System: The signal from the detector is typically amplified and processed by electronics. The results are then displayed on a readout system, which may include a digital display or be connected to a computer for data analysis.
