T-1218 Long-Range Bore Target

T-1218 Long-Range Bore Target



The T-1218 Large-Range Bore Target High accuracy and measuring range for large-bore centering applications Hamar Laser’s new T-1218 Universal Target is a 2-axis, large-range target designed for large-bore centering applications such as turbines or stern tubes. The T-1218 can be used with the T-1225(L) flange(s) adapter, the T-1230 target stand or custom fixtures. Compatible lasers include the L-700, L-705, L-706, L-708 and L-741.


20x20 mm PSD, offering twice the measuring range of the T-218 Target (note: T-1218 does not have see through capability. For a large-range see-through target, see the T-1220 datasheet) Higher accuracy, super-linear PSD with <1% error over the full measuring range Compatible with the R-1307 Series of readouts (the R-1307C, R-1307-900, R-1307-2.4 and A-910-2.4ZB) and Hamar Laser alignment software.
