Rate.When whether being alignd using convex lens sem observation concentric scale line with circular hole, it is necessary to observe the concentric scale on scale plate simultaneously
Line and the circular hole below concentric scale line, because convex lens can only be focused on a point, otherwise the focus of convex lens is poly-
Jiao is in concentric scale line, otherwise focus on circular hole, such as when focusing on concentric scale line, the imaging for the circular hole seen
Relative to the fuzzyyer of concentric scale line.When scale plate is aspherical mirror, relative to conventional level crossing, circular hole can be allowed to exist
Acutance and the higher imaging of resolution ratio are formed on scale plate, now again by convex lens sem observation concentric scale line and circular hole in scale
During imaging on piece, can more clearly seeing concentric scale line clearly, whether the imaging with circular hole on scale plate is alignd, Jin Ergeng
Facilitate deciding on whether concentric scale line aligns with circular hole.Also, convex lens are usually spherical mirror, spherical mirror easily produces sphere
Aberration, cause light to converge to focus, so as to cause image blur, be unfavorable for accurate observation concentric scale line whether with circle
Align in hole.It when scale plate is aspherical mirror, can be advantageous to light collection to focus, and then effectively eliminate caused by convex lens
Spherical aberration, and then it is more beneficial for whether accurate observation concentric scale line aligns with circular hole.
