Right-Angle Mounting Adapters for Breadboards
Large Right-Angle Bracket
Two AB90 Brackets Mounting an MB1218 Breadboard to an Optical Table
The brackets and plates featured on this page allow for our Solid Aluminum Breadboards to be mounted at 90° to an optical table. The mounting bracket or plate most appropriate for breadboard mounting depends on the size of the breadboard and the setup. For example, the AP90RL is ideal for use with larger breadboards requiring central support, whereas the VB01A is ideal for smaller breadboards requiring outer support. We recommend mounting only our smallest breadboards using the small right-angle brackets and plates.
All parts shown here are constructed from single aluminum blocks, providing exceptional precision and rigidity. Dimensions of each bracket and plate are provided in the PDF drawing under Docs (), located next to the Part Number, below. Each mounting bracket or plate can be attached to our solid aluminum breadboards using our cap screws and balldrivers.
These Vertical Brackets are designed to mount any of our aluminum breadboards vertically on an optical table. The edges contain 1/4" (M6) clearance holes and 1/4"-20 (M6) tapped holes at regular spacings, providing a high degree of mounting flexibility. The VB01A(/M) has three 1/4"-20 (M6) tapped holes along the 45° edge for additional mounting options. 6", 11.75", and 18" tall brackets are available.

Two AP90RL Brackets Connected by an Arched Slot
The AP90RL(/M) Large Angle Bracket is a heavy-duty component ideal for mounting breadboards and other bulky optomechanics at right angles to an optical table. The front, sides, and top contain a generous array of 1/4"-20 (M6) tapped holes and clearance holes, and the front additionally provides two parallel 2.40" (61 mm) long clearance slots. The base contains two 1/4"-20 (M6) clearance slots and five clearance holes, as well as two arched 1/4"-20 (M6) slots that provide continuous rotation of ±50° prior to fastening the bracket down.
The AP90(/M) Right-Angle Plate is an ideal solution for building sturdy three-dimensional optomechanical assemblies that require vertical positioning. This plate provides four 1/4"-20 (M6) clearance slots, seven 1/4"-20 (M6) tapped holes, and two 1/4"-20 (M6) counterbores oriented at 90° from the optical table surface. Its base contains two 1.30" (34 mm) long, 1/4"-20 (M6) clearance slots and two 1/4"-20 (M6) counterbores for mounting to an optical table.
Our AP90L(/M) Large Right-Angle Plate is a heavy-duty mount, capable of holding breadboards at 90° relative to an optical table's surface. This plate provides a generous array of 31 1/4"-20 (M6) tapped holes and six 1/4"-20 (M6) counterbores oriented at 90° from the optical table surface. Its base contains three 1/4"-20 (M6) clearance slots and six 1/4"-20 (M6) counterbored holes for mounting to an optical table.
For an alternative 90° mounting option, the top plate on our AP180 Adjustable Angle Plate can be positioned to provide mounting configurations similar to the AP90. Thorlabs also offers 45° and 30°/60° mounting plates.
Our MSAP90(/M) Mini-Series Right-Angle Plate, based upon our popular AP90 Right-Angle Plate design, is an ideal solution for constructing rigid three-dimensional assemblies with our Mini-Series components. This bracket provides four 4-40 (M3) clearance slots, seven 4-40 (M3) tapped holes, and two 4-40 (M3) counterbores oriented at 90° from an optical table surface. Its base contains two 1.0" (25.4 mm) long, 4-40 (M3) clearance slots and two 4-40 (M3) counterbores for mounting to a Mini-Series Breadboard.
