SMR Target Holders, Adaptors and accessories for use with Laser Trackers

Used for 3D measurements such as laser trackers and photogrammetry, these holders provide accurate cost effective holders for SMR reflectors.

This range of SMR targetholders is available for use with 1.5, 0.875 and 0.5in SMRs (CCRs)reflectors and with a range of diameters and offsets to suit your requirement, including:

  • THDN Drift Nests

    THDN Drift Nests

    Magnetic, flat back drift nests for use as temporary targets on almost any surface.  Negative drift nests also available.

  • TH Standard Target Holders

    TH Standard Target Holders

    Shank mounts, for mounting in a selection of hole diameters to suit your requirement – select the shank diameter and offset to suit your application

  • THSB Diamond shank Target Holders

    THSB ‘Diamond shank’ Target Holders

    Mounts for use with slotted bushings

  • THS shankless target holder

    THS shankless Target Holder

    This magnetic adapter provides an SMR nest which fits into any corner and puts a 1.5" diameter SMR exactly 0.800" away from the rising surface, within ±0.0005".

  • THE Edge Target Holders

    THE Edge Target Holders

    This magnetic adapter provides an SMR nest which locates an edge within ±0.0005" (for outside corners)

  • THF permanent floor and reference mounts

    THF permanent Floor and Reference Mounts

    This floor target mount provides for a permanent target location in the floor or wall.

  • THCP centre punch

    THCP Centre Punch

    This magnetic adapter is an SMR nest doubles as a transfer punch locator, allowing you to mark a point directly under the SMR.

  • 1.5ADP 1.5in (38mm) adaptors

    1.5ADP 1.5in (38mm) Adaptors

    to accurately hold smaller SMRs (CCRs)

Target Holders in custom sizes:

We can supply target holders to meet your specific size requirements - most variations are available - just contact us with your dimensions or drawings.

Serialized and Certified Target Holders:

You use laser trackers to achieve the maximum quality from your manufacturing processes but how do you know how accurate your SMR target holders are? Target Holders are a critical part of any Laser Tracker System and Brunson Instruments can provide certification and serialization with these accessories where required.

Rather than a simple Pass-Fail test, each critical dimension is measured precisely and shown on the Certificate that comes with the target holder. These certified dimensions can be used by the operator instead of relying on a generalized tolerance range – improving the actual measurement made by your 3D laser instrument. The end result: less stackup error and reduced uncertainty.

Each dimension certified by Brunson is taken using a UKAS-traceable process. A laser-etched serial number identifies the target holder for easy component management.
