摘要： PURPOSE: To prevent a split prism from being darkened even if a dark lens is used or a diaphragm is stopped by forming a ridge line group symmetrical about a line vertical to the displacement direction of a defocused image by wedge prisms on the surface of the split prism.
CONSTITUTION: Two wedge prisms 2a, 2b are formed on the center part of a mat surface 1a of a reticle 1. The 1st and 2nd direction ridge line groups are formed on the inclined surface of the wedge prism 2a along the 1st and 2nd directions l
1 , l
2 respectively which are symmetrical about a line vertical to the displacing direction of a subject by the prism 2a. Respective ridge lines constituting the 1st ridge line group are formed by the 1st and 2nd inclined surfaces along the 1st direction and respective ridge lines constituting the 2nd ridge line group are formed by the 1st and 2nd inclined surfaces along the 2nd direction. A quadrangular pyramid-like groove expanded in the direction vertical to the displacing direction of the subject by the prism 2a is formed on the surface of the prism 2a. The wedge prism 2b is similarly treated.

摘要： PURPOSE: To prevent a slit prism part from being darkened even if a dark prism is used or a diaphragm is stopped by forming prism string groups symmetrical about a line vertical to the displacing direction of a defocused image by wedge prisms on the surface of the slit prism.
CONSTITUTION: Two wedge prisms 2a, 2b are formed on the center part of a mat surface 1a of a reticle 1. The 1st and 2nd direction ridgeline groups are formed on the inclined surface of the wedge prism 2a along the 1st and 2nd directions l
1 , l
2 respectively which are symmetrical about a line vertical to the displacing direction of a subject by the prism 2a. Respective prism strings of the 1st and 2nd prism string groups are constituted of a parallelogramic quadrangular pyramid-like fine prism structure extended in a direction vertical to the displacing direction of the subject by the prism 2a. The wedge prism 2b is similarly treated.

摘要： PURPOSE: To prevent a split prism part from turning dark even when a lens is dark or stopped down by forming the 1st ridge prism with the 1st width and the 2nd ridge prism with the 2nd width aperiodically on the surface of a wedge prism.
CONSTITUTION: Two wedge prisms 2a and 2b are formed on the mat surface 1a of a focus plate 1. The 1st ridge prism P
1 of the 1st width which has a ridge line almost at right angles to the displacing direction of a subject image formed by the wedge prism 2a and the 2nd ridge prism P
1 of the 1st width which is wider than the 1st wedge prism P
1 are arrayed aperiodically on the slanting surface of the wedge prism 2a to constitute a group of ridge lines. The wedge prism 3b is the same.
