Embodiment 1

[0033] Such as Figure 1-3 As shown, the multi-functional ophthalmic examination equipment according to the embodiment of the present invention includes an OCT imaging system or / and a fundus photography system. It also includes a front segment lens group 12 and an alignment system. The front segment lens group 12 includes two groups of lenses, and each group of lenses in the two groups of lenses can be one piece, or a lens group composed of two or more lenses. There is a distance between the two groups of lenses, the distance is greater than or equal to 4mm, and the distance satisfies that the conjugate plane of the fundus and the ocular surface is between the two groups of lenses, and the focal lengths of the two groups of lenses are both positive focal lengths, satisfying the conjugation in the optical system The image plane is between the two sets of lenses, not near the lens surface.

[0034] In actual production, the OCT imaging system, the fundus photography system and ...

Abstract

The invention discloses multifunctional ophthalmic examination equipment which comprises an OCT imaging system or / and a fundus photographing system. The front-section lens group comprises two groups of lenses, and a distance is formed between the two groups of lenses; when the front section lens group is cut in, light passing through the continuous lens passes through the front section lens group and the eyepiece and then is focused on the ocular surface, and when the front section lens group is not cut in, the light passing through the continuous lens passes through the eyepiece and then enters the eye ground. Various ophthalmology detection systems are organically integrated on one device, multiple purposes are achieved through one device, modularization can be achieved, arbitrary addition and reduction of multiple functions are achieved, a user purchases different modules according to the requirements of the user, and the requirements of the ophthalmology market are fully met.

Description

technical field [0001] The invention relates to ophthalmic examination equipment, in particular to a multifunctional ophthalmic examination equipment. Background technique [0002] Generally speaking, for eye examination equipment, most of the common ones on the market measure a certain type of parameters by classification, such as: [0003] Optical coherence tomography (OCT) is an emerging non-contact, non-invasive ophthalmic imaging diagnostic technology. structure. The fundus camera illuminates the fundus through a special lighting system, and the fundus obtains the processed image on the photoelectric sensor through the imaging system. Observation and OCT imaging device of the anterior segment. [0004] However, at present, there is no device that organically integrates multiple functions on one machine, realizes the compactness and portability of the device, realizes one machine with multiple functions, and each function is modularized to fully meet the needs of the ...
