The BE1R has a magnet in the base for stability in temporary setups.

• Mount 1/4"-30 (M6) or 8-32 (M4) Tapped Components in an Arbitrary Position 0.19" (4.7 mm) Above the Breadboard
• Clamping Fork or CL8 Table Clamp Secures Base to a Breadboard or Table
• 1/8" (3 mm) Hex Socket on Bottom for Tightening (Click the Zoom Link to the Left for Photograph)
• Machined Bottom Relief Cut for Added Stability

The BE1(/M), BE1R(/M), and BE2(/M) Studded Bases allow 1/4"-20 (M6) or 8-32 (M4) tapped optomechanical components to be mounted in an arbitrary position 0.19" (4.7 mm) above the breadboard. The BE1R(/M) adapters additionally have a magnet in the base that is sufficiently strong to securely hold the base in place without clamping to an optical table. These bases are Ø1.25" (Ø31.8 mm) and feature a 1/8" (3 mm) hex socket on the bottom for tightening.

To secure the base, a clamping fork (shown in the photo to the right) or a CL8 table clamp can be used. The BE1(/M) base adapter is available in a pack of five for ease of ordering.

A POLARIS-K05F6 Ø1/2" Mirror Mount is shown on a BE2T Base secured to the breadboard by two CL8 Table Clamps. Please note that a 3/8" (10 mm) long 8-32 (M4) low-profile cap screw is recommended for mounting the Polaris onto this base.

• Mount Counterbored Components in an Arbitrary Position 0.19" (4.7 mm) Above the Breadboard
• 8-32 (M4) and 1/4"-20 (M6) Tapped Versions Available
• CF125 or CF175 Clamping Fork or CL8 Table Clamp Secures Base to a Breadboard
• Machined Bottom Relief Cuts for Added Stability

The BE2T(/M) and BE1T(/M) Tapped Bases allow counterbored optomechanical components to be mounted in an arbitrary position 0.19" (4.7 mm) above the breadboard. The BE2T(/M) offers an 8-32 (M4) tap, while the BE1T(/M) has a 1/4"-20 (M6) tap. 

To secure these Ø1.25" (Ø31.8 mm) bases, a CF125 or CF175 clamping fork or a CL8 table clamp (shown in the photo to the right) can be used. However, using these items will restrict the width of the component being mounted to a maximum of 1".

• 0.66" Long, 1/4"-20 (M6) Threaded Mounting Stud
• CF125 or CF175 Clamping Fork (Sold Separately) Secures Base and Locks Swivel Joint 
• ±6° Swivel Compensates for Uneven Surfaces
• Locking Nut Included for Height Adjustments
• 1/8" (3 mm) Hex Socket on Bottom for Tightening
• Machined Bottom Relief Cut for Added Stability

Thorlabs' SWB(/M) Articulated Mounting Base can be used to stabilize and level a mounted component, such as a breadboard, or to correct for beam pointing errors. It features a 0.66" long, 1/4"-20 (M6) threaded mounting stud with ±6° of freedom in all directions to adjust for uneven work surfaces or compensate for angular misalignment. The base can be secured to an optical table or breadboard using a clamping fork, such as the CF125 or CF175, as shown in the photo to the right. Securing the base in place with a clamping fork will lock the articulated joint in position.

A Ø1" tapered locking nut is included for components requiring a larger support surface and provides 0.375" of vertical height adjustment. The tapered design prevents the locking nut from contacting a clamping fork when being secured in place. Additionally, torque holes that accept a 5/64" hex key are included in the lock nut and mounting stud to aid in securing a mounted component at a specific height. A 1/8" (3 mm) hex socket is also included on the bottom of the mounting base to actuate the threaded mounting stud.

An FW102C Motorized Filter Wheel is mounted on a PB4 Base, which is secured to the table with a CL8 Table Clamp.

• Mount 1/4"-20 (M6) Tapped Components in an Arbitrary Position 0.24" (6.1 mm) Above the Breadboard
• PF175B Clamping Fork or CL8 Table Clamp Secures Base to a Breadboard or Table
• 1/8" (3 mm) Hex Socket on Bottom for Tightening
• Machined Bottom Relief Cut for Added Stability

The PB4(/M) Studded Base allows 1/4"-20 (M6) tapped optomechanical components to be mounted in an arbitrary position 0.24" (6.1 mm) above the breadboard. This Ø1.85" (Ø47.0 mm) base has a 0.26" (6.6 mm) long, 1/4"-20 (M6) stud on the top and a 1/8" (3 mm) hex socket on the bottom for tightening.

To secure the base, a PF175B clamping fork or a CL8 table clamp (shown in the photo to the right) can be used. However, using these items will restrict the width of the component being mounted to a maximum of 1.5".
