Wild Heerbrugg GLO laser
Wild Heerbrugg GLO laser eyepiece
Obtained from Poland
A 'new old stock' instrument obtained from Poland. Always a gamble with electronics, but so far Wild Heerbrugg instruments usually still work even after decades. So did this one; it fired up the first time. Technically Wild probably only made the eyepiece as the laser itself is clearly labelled 'Hughes'.
Setting it up was a bit of a puzzle though. The eyepiece uses a semi-transparent mirror angled at 45 degrees which will convey the laserdot through the telescope (and the eypeiece). The regular theodolite controls are then used to aim it using the red dot visible. The brightness of the dot in the eyepiece can be adjusted using a polarizing filter. I will post images of it on top of one of my theodolites at a later stage.
The accessory has a similar function as my laserline LR2020d. And although the Wild laser is much larger and based on its specs more powerfull (10 mW) I have not managed to get the same range as the Laserline. My test target, 900 m away, was nicely illuminated by the Laserline but not by the Wild. On the other hand, the Wild seems to have a smaller pattern. A shorter range of around 150 m was no problem.
