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 devices observe Newton's ring with reading microscope, pass 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 rotating 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 operates and still has any problem after causing teacher to explain.So needs one are in SGH-1 type EXPERIMENT OF NEWTON ' S devices
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, student is enable clearly to observe teacher to SGH-1 types
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, the Teaching instrument holder that neither one is suitable, can be fixedly mounted on SGH-1 type EXPERIMENT OF NEWTON ' S devices
Above-mentioned video camera is adjusted with displacement.
