Caution1: Chamfer of concave mirror is identical to Spherical Lens.
Caution2: Chamfer finish is for protection to suffer from chipping, and the amount of chamfer may vary.

* Some standard parts has other tolerance than above data.
Caution1: Chamfer finish is for protection to suffer from chipping, and the amount of chamfer may vary.
Prisms have sharp edges because of its function and therefore usually needs protective bevels.
Outer dimensions of prisms are noted by length without bevels.
Chamfer finish is for protection to suffer from chipping, and the amount of chamfer may vary.
