Embodiment Construction
[0023] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] A compact wide-field-of-view white light sight optical system of this embodiment adopts a Keplerian telescopic system, including an objective lens group, a relay image group, a reticle and an eyepiece group. The object to be measured generates an inverted image through the objective lens group, and is imaged on the reticle after the image transfer group, and the inverted image formed by the objective lens is erected, and finally reaches the human eye through the eyepiece group. The distance between the objective lens group and the relay group is 48.3mm, the distance between the relay group and the reticle is 24.84mm, and the distance between the reticle and the eyepiece group is 7.9mm.
[0025] Such as figure 1 As shown, the objective lens group adopts 2 groups of 3 spherical lenses, including the first lens group 1 ...
