The invention discloses a composite light-transmitting type solar image projector. A convex lens and a concave lens, which are overlapped with each other, are arranged in a cylinder. A telescopic lens barrel is connected to one end of the cylinder, wherein the concave lens is arranged at the end. A microscope lens which is a 15X microscope lens is arranged at one end of the telescopic lens barrel. The composite light-transmitting type solar image projector has the advantages that: by overlapping the convex lens and the concave lens, an object can be more clearly observed; by using the telescopic lens barrel and the microscope lens, clear solar faculae can be projected; a total solar eclipse can be observed in a mode of observing a solar image projection; and the composite light-transmitting type solar image projector is simple in structure and convenient to use.
Description
technical field [0001] The invention relates to a projection device, in particular to a composite light-transmissive solar image projector for watching total solar eclipse. Background technique [0002] A total solar eclipse is a rare astronomical spectacle, but it cannot be viewed with the naked eye without any protective measures. It will cause damage to the eyes. The existing viewing equipment is expensive and has a complicated structure. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a composite light-transmitting sun image projector, which can watch a total solar eclipse by watching the sun image projection, and has a simple structure and is easy to use. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a composite light-transmitting solar image projector, the cylindrical body is provided with overlapping convex lens sheets and ...
