The long range linear optics kit is to be used with the ML10X for linear measurements in excess of 40 m.
These optics enable linear measurements to be taken on axis lengths to 80 m.
The kit includes: a large retroreflector and target (to enable easier alignment at long range) and a periscope assembly which ‘captures’ the return beam and redirects it into the laser shutter.
XL-80 range = 80 m
ML10 standard range is 40 m; ML10X is required for 80 m range.
