         Introduction and characteristics of 5 micron slit: slit is mainly used in spectral instruments, etc. According to the working principle of modern spectral instruments, spectrometer can be divided into two categories: classical spectrometer and new spectrometer. Classical spectral instruments are instruments based on the principle of spatial dispersion. The new spectral instrument is an instrument based on modulation principle. Classical spectrometers are slit spectrometers. Modulation spectrometers are non-spatial spectrometers. According to the principle of dispersive component, spectrometer can be divided into: prism spectrometer, diffraction grating spectrometer and interference spectrometer.

        The difference between a slit plate and a polarizer: the polarizer passes through a specific crystal structure so that only light in the direction of transmission can pass through the polarizer. So when you go through the polarizer, natural light becomes polarized light, just vibrating in one direction. The slit does not have the ability to convert natural light into polarized light. When the width of the slit is close to or less than the wavelength of light, the light passing through the slit will have obvious diffraction phenomenon and the propagation direction will change. But the light still vibrates in all directions after it passes through.

•   Application fields of slits: 1. Incident slits: object points that form the spectrometer imaging system under the irradiation of incident light. 2. Collimating element: causes the light emitted from the slit to become parallel. The collimating element may be a separate lens, reflector, or directly integrated on a dispersion element, such as a concave grating in a concave grating spectrometer. 3. Dispersion element: grating is usually used to disperse the optical signal into multiple beams in space according to the wavelength. 4. Focusing element: focusing the dispersive beam so that it forms a series of images of incident slits in the focal plane, where each image point corresponds to a specific wavelength. 5. Detector array: placed in the focal plane to measure the light intensity of each wavelength image point. The detector array can be a CCD array or other kinds of optical detector array.
