Description of the Invention: [Technical Field] The present invention relates to a single-focus lens group used in a general digital camera, and particularly relates to a thin lens configured by using a four-lens lens. Form a mirror group. [Prior Art] In the conventional single-focus lens group used in today's digital cameras, the general single-focus digital camera lens is rapidly attenuated because the sensitivity of the photosensitive element increases with the incident light angle, so the general single-focus digital camera lens is The front and back positive lens structure (known in the industry as Inverse Tel-printed HOTO structure); in practice, the aforementioned conventional lens is composed of 5 to 6 mirrors #, and the first lens will adopt a crescent-shaped convex surface facing forward. The configuration of the lens structure and the conventional single-focus digital camera lens still have the following technical difficulties after being used: - The conventional single-focus digital camera lens has a curvature of the rear surface of the first lens in order to make the exit angle of the lens smaller. The radius needs to be as small as possible, but the derivation of this work is that the height of the optical system will increase, so the [the lens after the lens ^ is not reduced by the moon, so the optical system of this configuration is always $ The degree (ie can no longer be reduced). One of them, the use of a single-focus digital camera lens for a small day, while the 4 i25r-it increases the 3rd-order coma and astigmatism together. Therefore, the lens group of a single-focus digital camera lens needs to be spent. More lenses correct the above problems. If the market demand for high resolution is required, the rear group of conventional lenses often needs 4 lenses. The conventional single-focus digital camera lens is sometimes used to reduce the number of lenses. Spherical plastic lens, used to overcome aberrations, but the plastic lens has thermal effects, the design can not be arbitrarily configured; therefore, the conventional single-focus digital camera lens practice is mostly /, the first lens and the last lens in the optical system are aspherical Plastic lens replacement, such a thing can only slow down the aberration, it does not help the overall space reduction. ^ In order to be able to effectively solve the practical problems of the conventional single-focus digital camera lens, the creator has finally developed the present invention based on the technology and experience accumulated in the field of optical equipment in the past, that is, the space saving and the increase of the efficiency. Thinly forming a new type of image group, and achieving a reduction in the volume of the lens group and obtaining a high resolution. The first objective of the month is to provide a thin-form image lens group that can reduce the volume of the lens group and take into consideration the high resolution. In addition to the J gauge basket, it consists of a mirror, a second lens and a fourth lens.
