Glass sphere prism (Supercateye SCE 1.5''). The SCE 1.5'' is a target
with a very large acceptance angle. The glass ball is centered in a
metal sphere and can be used with the same reector nest as other
1.5'' reectors.
Reector Type Maximum Entry Angle
RRR/BRR ±30°
TBR ±22°
SCE 1.5" ±75° vertical
±360° horizontal
Most reectors are housed in a metal ball (Spherically mounted reector,
SMR), with the advantage of a constant offset when measuring surfaces. A
three-point reector support ensures reliable centering of the sphere.
A reector support is used, when the reector needs to be xed in a particu-
lar stable position. A magnet in the reector support holds the reector in
the same position. Various kinds of reector supports are available.
☞
Refer to the brochure “Hexagon MI Laser Tracker and Accessor-
ies Catalog” for detailed information.
A dropped reector may be damaged, which will affect the measuring accur-
acy (trueness of the optics and centering). Damages may not be immediately
apparent. Dropped reectors should be sent to your authorised Hexagon
representative or distributor for inspection.
☞
Secure the reector with a lanyard when moving the reector.
