Are as follows: the very big plano-convex lens of a radius of curvature downward with its convex surface are placed on one flat plate glass, therebetween formed from
The air film of center phase periphery progressive additive, if projecting monochromatic collimated beam, air film lower edge face and upper limb face to vertical lens
The light of reflection will meet near air film upper limb face and be interfered, and a series of light and shade phases centered on glass contact point occur
Between annulus, i.e. Newton's ring；SGH-1 type EXPERIMENT OF NEWTON ' S device observes Newton's ring with reading microscope, passes through reading microscope
Scale reading on the outer microdrum of scale and eyepiece in eyepiece field of view measures the diameter of Newton's ring.It is also wanted in measurement process
Make the ring heart of interference ring and be transferred to the visual field center of reading microscope, then by rotation eyepiece, graticle is focused, until making to regard
Field internal interference ring is clear.
But in above-mentioned adjusting, measurement and reading process, the variation of reading microscope visual field internal interference annulus and focal length,
Reading only one people of operator outside eyepiece on microdrum can see that when operation of teacher is explained, student does not see these
Details, student's operation is still had any problem after causing teacher to explain.So needs one are in SGH-1 type EXPERIMENT OF NEWTON ' S device
Installation is connected with the video camera of display, the amplification by video camera to eyepiece and microdrum respectively at eyepiece and micrometer handwheel
Shooting, and by amplified image projecting on large screen display, enable student clearly to observe teacher to SGH-1 type
The adjusting of EXPERIMENT OF NEWTON ' S device, become can vision-control EXPERIMENT OF NEWTON ' S device when eyepiece and adjust hand button reading
Teaching instrument.But currently, none suitable Teaching instrument bracket, can be fixedly mounted on SGH-1 type EXPERIMENT OF NEWTON ' S device
Above-mentioned video camera is adjusted with displacement.

The reading area of micro- drum.The height of secondary camera can unclamp the fixed jackscrew up and down moving pairs camera of secondary camera to adjust
Section.
The main camera is general small size VGA or video output interface camera, and shell sizes are no more than 60mm
(width) * 60mm (height) * 70mm (optical axis direction length), the pair camera is 400-1000 times of endoscope (also referred to as high definition of pen type
Digital electric microscope).
Benefit of the invention is that: the images that 1. present invention arrive sem observation on reading microscope by two cameras with
The read text scale of microdrum shows with display simultaneously, and solving class hour teacher, to explain other students invisible specific
The problem of details；2. the position of adjustable two cameras all around guarantees master with by way of magnet absorption installation
The eyepiece of camera face reading microscope, the read text scale of secondary camera face microdrum；3. vertical direction on frame
The height and angle of elongated slot and adjustable two cameras of main camera fixed screw keep shooting image size suitable, clearly
Degree is high；4. the headlamp of band, can guarantee clear reading in dark room conditions on secondary camera.4. having magnet absorption installation, no
Influence the structure and function of former instrument, when use sucts, and removes when not used, easy to operate.
