Embodiment Construction

[0022] Below in conjunction with specific embodiment the present invention is described in further detail:

[0023] Such as figure 1 As shown, the new mobile phone microscope system based on two PDMS plano-convex lenses in this embodiment includes a micro device and a mobile phone 5, and the micro device includes a mobile phone clamping device 1, a lens group 2, a light source 4 and a sample box 7. The light source 4 is located below the lens group 2 and is set in the sample box 7 . The mobile phone 5 is placed on the holding device 1 , and the lens of the mobile phone 5 is located above the lens group 2 . The sample is placed in the sample box 7 and located between the lens group 2 and the light source 4 .

[0024] Wherein the lens group 2 comprises: the first lens 8, the second lens 9 and a fixed mould, the specific structure sees image 3 . The first lens 8 is a plano-convex mirror with a plane facing upwards and a convex surface facing downwards; the second lens 9 is a...

Abstract

The invention discloses a double-lens microscopic system with an ultra-short focal length. The double-lens microscopic system comprises a microscopic device and a mobile phone, wherein the microscopicdevice comprises a lens group and a light source, and the lens group is composed of two plano-convex lenses with opposite convex surfaces; and the light source is located below the lens group, and acamera lens of the mobile phone is placed above the lens group. The microscopic device has the advantages of high magnification times, high resolution, small edge distortion, low cost, small size andportability, can achieve high-quality magnification imaging when being matched with the mobile phone for use, and has very wide application prospects in complex scenes, especially in the aspect of home diagnosis and treatment.

Description

technical field [0001] The invention relates to the technical field of microscope imaging applications, in particular to an ultra-short focal length double-lens microscope system. Background technique [0002] With the rapid development of mobile phone technology, existing smart phones are increasingly closely integrated with people's daily work and life. Considering the high popularity and relatively low price of mobile phones, as well as their own high-definition image recording and storage capabilities, as well as the complete image processing and electronic magnification functions of the supporting software, a microscopic system is prepared around mobile phones to replace traditional bulky and expensive ones. Expensive microscopic devices have extremely broad market prospects and have become a research hotspot nowadays. When building a mobile phone microscope system, the choice of lens is undoubtedly the most important thing. [0003] After a long period of development...
