A digital camera includes a mirror box having a lens mount to which a photographing lens is mounted; an image pick-up device having an imaging surface for capturing an object image which is focused on the imaging surface through the photographing lens; and a frame positioned inside the digital camera body, the mirror box and the image pick-up device being mounted to the frame. The mirror box is mounted to a surface of the frame. The image pick-up device is mounted to the surface of the frame via at least one support member positioned between the mirror box and the image pick-up device. A ratio of a distance from the lens mount to the frame and a length of the support member is substantially equal to a ratio of a linear expansion coefficient of the support member and a linear expansion coefficient of the mirror box.

A camera which includes a camera body includes a main body and a mirror box fixed to the main body. The mirror box and the main body are made of a first material having a first thermal expansion coefficient and a second material having a second thermal expansion coefficient, respectively, the second thermal expansion coefficient being smaller than the first thermal expansion coefficient. The mirror box is fixed to the main body by at least two fixing devices symmetrically disposed with respect to an optical axis.

The invention discloses a mirror-box-type all-cloudy day simulation device. The mirror-box-type all-cloudy day simulation device comprises an optical reflection structure, electric light sources, a light diffusion film and a frame structure. The frame structure is an enclosed structure and the horizontal cross section of the enclosed structure is in the shape of a regular polygon or round. The electric light sources are arranged at the spatial top of the frame structure and the light diffusion film is arranged below the electric light sources. The optical reflection structure is a mirror reflection material arranged on the inner side of the enclosed structure, the mirror reflection material is formed by connecting a plurality of plane mirrors in a seamless mode, and the included angle formed by the mirror reflection material and the plumb line is zero point seventy seven degree. The upper end of the optical reflection structure is connected with the light diffusion film, and the lower end of the optical reflection structure is located at the lower end of a detected model storing platform in the height direction. According to the mechanism that light of an even light-emitting face at the top is reflected infinitely through the enclosed mirror structure, the mirror-box-type all-cloudy day simulation device accurately simulates the standard all-cloudy day sky brightness distribution published by the International Illuminating Engineering Society. The mirror-box-type all-cloudy day simulation device has the advantages of being small in size, ingenious in structure, accurate in brightness distribution and the like, and can be used for simulating the sky brightness distribution during all-cloudy days.

The invention relates to the technical field of medical teaching equipment. The invention further discloses an oral medicine teaching mirror image training device. The device comprises a mirror box; rear cover inserting seats are fixedly connected to the top and the bottom of the right side of the mirror box; a rear cover inserting groove is formed in the surface of the right side of each rear cover inserting seat; and bearing mounting grooves are formed in the top and the bottom of the right side surface of a mounting base. A rotating handle is screwed to drive a screw rod to rotate so as topush the mounting base to move outwards, the mounting base drives a left connecting strip to pull a spring to slowly extend to control the displacement amplitude of the mounting base, the inner wall of the inner ring of the bearing is fixedly connected with the tail end of the screw rod through the horizontal line of the screw rod penetrating hole and the screw rod inserting hole, the angle of thescrew rod is ensured not to deviate when the screw rod rotates and displaces, so that the angle of a frontal mirror can be freely adjusted from the upper side or the lower side, and dead angles whichare not easy to observe can be observed more conveniently.

The invention provides a light guide (15) used for for delivering an illumination, in particular a reference or background illumination, the light guide comprising: a mirror box (21) which defines a mirror cavity (23), which receives a light source (19) therein, and includes an illumination aperture (25) from which illumination is delivered; a transmissive diffuser (27) which is located at the illumination aperture to render the illumination diffuse; and a shutter mechanism (41) which can be moved to the cavity to obstruct the light source and provide for control of the intensity of radiance of the delivered illumination. Thus, the control for the intensity of radiance of the delivered illumination can be determined by the position of the shutter in the cavity.
