Problems solved by technology

[0003] Among them, the applicant has previously proposed a number of lens groups related to infrared wavelength reception, such as: "Single Focus Wide-angle Lens Group SINGLE FOCUS WIDE-ANGLE LENSMODULE" of Taiwan Application No. 098100552 and No. 098125378, but the current game machine is based on More three-dimensional, realistic and immersive 3D games are the main focus, so the current or the applicant's previous lens sets are all based on 2D plane game detection, so that they cannot meet the depth sensing function that 3D games focus on
[0004]Furthermore, for the infrared receiving and sensing lens group dedicated to the game machine, plastic lenses are used in pursuit of low cost. Firstly, the poor light transmission of the material affects the game machine Depth detection accuracy is not enough as one of the key factors. Second, the plastic lens is prone to overheating or overcooling in the ambient temperature, so that the focal length of the lens group changes and cannot be accurately focused. As mentioned above, the current infrared wavelength receiving lens group cannot meet the requirements. Two major technical issues for accurate sensing of depth and distance in 3D games

Description

technical field [0001] The invention relates to a four-piece infrared single-wavelength lens set, in particular to a miniaturized four-piece infrared single-wavelength lens set applied to electronic products. Background technique [0002] Today's digital imaging technology is constantly innovating and changing, especially in the miniaturization of digital carriers such as digital cameras and mobile phones, and the photosensitive components such as CCD or CMOS are also required to be more miniaturized. In the application of infrared focusing lenses, in addition to using In the field of photography, it has also been widely used in the field of infrared receiving and sensing of game machines in recent years. In order to make the range of game machines sensing users wider, most of the lens groups that receive infrared wavelengths currently use lenses with larger picture angles. Wide-angle lenses are the mainstream. [0003] Among them, the applicant has previously proposed a nu...
