The black reference mark in the middle is the visual reference when the system is operated. The mirrors are adjusted vertically by tree screws and two water levels with high accuracy. The mirrors work in some ways as a retro cube and the view is reflected two times and then back to the operator and the reference edge he have.

The edge is balanced against the black reference targets on the mirrors until it is balanced between a reflex and no reflex from the black target. The changing position is then in exact 90 degree to the mirror surfaces.

The accuracy is very good and a trained operator can get 2 mm accuracy in the reference plane at 30 meter radius. This is better than most rotating lasers.

Here the miroscope is at the far end of site. The operator aligns his eyes with his reference edge and the place where the reflex is changed between the black target and the mirror surface. The changing position is very exact and easy to find. There the horizontal reference plane is located.

The Miroscope is a good alternative to a rotating laser and is prices at a fraction of the cost of the laser. There are no need for batteries in a laser or a receiver. How often have you wanted to use a system and there was empty or no batteries. The Miroscope makes life easier and better without this problems which is so common.
