(Hubbs Machine and Manufacturing: St. Louis) -- Hubbs Machine and Manufacturing Inc. has introduced the new cost-effective Sphere Mount  POLAR Series of laser tracker target holders.

The SM POLAR Series offers several features. The most prominent are:

• Its small footprint for mounting in tight areas • A unique locating nest with a substantially increased included angle • Negative rotation of the spherically mounted retroreflector (SMR) • Removable cap provides protection • 17-4 PH stainless steel standard, optional 1144 steel, with black oxide finish

The substantially increased included angle of the unique locating nest creates a much smaller, yet sufficient, locating diameter at the bottom (the “polar” region) of the SMR.

This balance of the smaller, three-point locating diameter at the bottom of the sphere plus the lessening of the depth of the nest, allows for negative rotation of the SMR all the way around while still maintaining stability of the SMR and the sphere mount. Additionally, the normal close-tolerance offset and concentricity are still held for the products that apply.

A small, sealed, easily removable cap is included to protect the nest from debris and contaminants, and it provides additional shielding of the three critical contact points within the nest from damage when not in use.
