UV transmission grating is an optical component designed for the ultraviolet (UV) wavelength range (usually 100-400nm). Its core function is to decompose composite ultraviolet light into monochromatic light of different wavelengths through the principle of multi slit diffraction. It is widely used in fields such as spectral analysis, laser technology, material detection, and communication.
UV transmission grating is an optical element used in the ultraviolet spectral region, mainly utilizing the diffraction effect of transmission grating to decompose ultraviolet light into spectra of different wavelengths. Its core function is to disperse the incident ultraviolet light into monochromatic light, facilitating the detection or analysis of material properties at different wavelengths.
A transmission grating is a spectral element that utilizes the diffraction phenomenon of light to decompose a beam into different wavelengths. Its basic structure is usually composed of a series of uniform slits or grooves, which produce different diffraction angles according to the wavelength of the light wave when the light passes through. In this way, the grating can separate light of different wavelengths to form a spectrum.
UV transmission grating achieves its function by engraving a large number of parallel slits or scratches of equal width and spacing on a transparent substrate, such as ultraviolet quartz glass. When ultraviolet light is incident:
Diffraction effect: Each slit acts as an independent light source, producing diffracted light;
Interference superposition: Diffraction light from different slits interferes with each other, forming diffraction fringes with alternating brightness and darkness;
Dispersion separation: The diffraction angle is wavelength dependent, and light of different wavelengths is dispersed to different angles to form a spectrum.
Component inspection and maintenance
Belt replacement: If the belt is found to be worn or the screws are loose (such as abnormal noise on the X-axis), it is necessary to replace the appropriate screws and adjust the tightening force to ensure that the belt tension is moderate.
Calibration check: Regularly use a calibrator to check the synchronization accuracy of the grating lines, and recalibrate if the deviation exceeds ± 1 °.
