Spectral transmittance difference
The spectral transmission of the lens also contributes to the sharpness of the picture. The transmission of wide frequency light will greatly increase the amount of light received by the camera's target surface. Can enhance the contrast and brightness of the picture, and it is richer in the details of the picture.
Spectral correction ability difference
Only wide-spectrum transmission power is not enough for high-definition imaging. If the lens's spectral correction ability is insufficient, some wavelengths of light will not be accurately imaged on the camera's target surface, resulting in virtual images. This technique is not possible with ordinary lenses through coating.
Sharpness difference
The resolution of the lens at the center of the imaging plane is the highest, and the picture at the edge is relatively poor. While the normal lens can basically satisfy the definition at the center, the sharpness of the edge will be reduced a lot, and the overall definition can meet the requirement of 440,000 pixels for an ordinary camera.
In fact, there are three key factors that determine the sharpness of the lens: 1. Lens material and purity. The less impurities in the lens, the less interference light it produces, the higher the resolution of the picture; 2. The grinding accuracy of the lens. The grinding precision of the lens is determined by the grinding equipment. At present, the difference between the domestic lens and the foreign lens is reflected in this point; 3, the coating accuracy of the lens. Accurate control of the coating process is also one of the determinants of lens definition.
In addition, the use of aspherical lenses for megapixel lenses reduces aberrations, improves the clarity of the lens compared to ordinary lenses, and enables miniaturized designs. Through special optical design techniques, image quality is achieved from the center of the image to the periphery. High-resolution, high-contrast images provide about 2.5 times more resolution than conventional lenses, ensuring high image quality even when the image is cut or enlarged. 
At present, megapixel lenses are more commonly used fixed-focus, manual zoom, power zoom and so on. For security applications in different industries, there are basically more mature applications. For example, in the area of ​​traffic capture, a fixed-megapixel camera is commonly used. What is the difference between a megapixel camera and an ordinary camera?
