Post-Mountable V-Clamps

Features

  • Clamp Clylindrical Objects Ranging from Ø1/32" (Ø0.8 mm) to Ø2.04" (Ø51.8 mm)
  • V-Clamp Lengths from 0.42" (10.7 mm) to 6.0" (152.4 mm)
  • Clamping Arm Provides Stable, 3-Point Contact with the V-Clamp
  • Post Mountable Using 8-32 (M4) Tapped Holes

These post-mountable V-Clamps are available in four distinct models, each designed for different cylindrical mounting requirements. Each model offers a solid, one-piece V-clamp body accompanied by a clamping arm whose contact area is positioned directly in-line with the center of the 'V'.

While most commonly used to hold cylindrical objects such as GRIN Lenses (VH1), Fiber Collimation Packages (VC1), Laser Diode Modules (VC3), and HeNe Lasers (VC6), these mounts are excellent general-purpose mounts capable of holding even unusually shaped objects. The V-shaped body and vertical clamping arm offers a stable, three-point contact resulting in stable component mounting. The V-clamps can be secured to a post via 8-32 (M4) tapped holes; the VC6(/M) additionally features six 1/4"-20 (M6) counterbores.

Response from Tor at Thorlabs to anonymous poster: Thank you for your feedback. We apologize for any inconvenience you’ve had while using the PM1. We are aware of the shortfalls of the current design and are releasing an improved design in the next week. We would love to give you the opportunity to try the new design; please contact us at techsupport@thorlabs.com if you would like us to send you some samples.

The brass screws break too easily in this design!

VH1 V-Clamp Holding a GRIN Lens
  • Clamps Cylindrical Objects Ranging from Ø1/32" (0.8 mm) to Ø3/8" (9.5 mm)
  • Compact Design Ideal for Small Optomechanical and OEM Assemblies
  • Post Mountable via #8-32 (M4) Tapped Hole

This miniature V-clamp is ideal for applications that require the positioning of short, small diameter cylindrical components, such as our GRIN Lenses, ranging from Ø1/32" (0.8 mm) to Ø3/8" (9.5 mm). The VH1 measures just 0.42" (10.7 mm) from front to back, a compact design that allows close access to both ends of a cylindrically shaped optic fastened within the mount. Cylindrical objects are clamped in place via a nylon-tipped setscrew, using a 5/64" (2.0 mm) hex key, housed in an adjustable height arm. One bottom-located 8-32 (M4) tapped hole makes this V-clamp directly compatible with our Ø1/2" posts.

Post-Mounted VC1 V-Clamp Holding a Fiber Collimation Package
  • Clamps Cylindrical Objects Ranging from Ø0.02" (0.5 mm) to Ø0.82" (20.8 mm)
  • Post Mountable via Two 8-32 (M4) Tapped Holes
  • One PM3(/M) Clamping Arm Included with Each Mount

The VC1(/M) Small, 0.75" (19.1 mm) Long V-Clamp is ideally suited for holding small cylindrical objects such as our Fiber Collimation Packages. Cylindrical objects are clamped in place using the nylon-tipped setscrew on the included PM3(/M) Clamping Arm (one included with each mount; additional arms are available below). This setscrew can be tightened with a 5/64" (2 mm) balldriver or hex key.

The PM3(/M) clamping arm is held to a post using a flexure locking mechanism that locks with the same 5/64" (2 mm) hex key. The post of the PM3(/M) includes a Ø0.09" (Ø2.3 mm) through hole that allows for extra torque to be applied when tightening.

This V-Clamp is equipped with one bottom-located and one side-located 8-32 (M4) tapped hole for post mounting. The side-located hole is opposite the clamping arm.

  • Post Mountable via Three 8-32 (M4) Tapped Holes
  • One PM4(/M) Clamping Arm Included with Each Mount

This 2.5" (63.5 mm) Long, Large V-Clamp is designed to hold large cylindrical objects such as our Laser Diode Modules.

This setscrew can be tightened with a  5/64" (2 mm) balldriver or hex key.

The PM4(/M) clamping arm is held to a post using a flexure mechanism that locks with the same 5/64" (2 mm) hex key. The post of the PM4 includes a Ø0.09" (Ø2.3 mm) through hole that enables the use of added torque when tightening.

For extra clamping support, this V-clamp has two additional (three total) 6-32 (M4) tapped holes for use with extra PM4(/M) clamping arms. Three bottom-located 8-32 (M4) tapped holes are provided for post mounting.

  • Post Mountable via Three 8-32 (M4) Tapped Holes or Six 1/4"-20 Counterbores
  • One PM4(/M) Clamping Arm Included with Each Mount

This 6" (152.4 mm) Long, Large V-Clamp is designed to secure long cylindrical objects, such as our HeNe Tube Lasers. Cylindrical objects are held in place using the nylon-tipped setscrew on the included PM4(/M) Clamping Arm (one included with each mount). This setscrew can be tightened with a  5/64" (2 mm) balldriver or hex key.

The PM4(/M) clamping arm is held to a post using a flexure mechanism that locks with the same 5/64" (2 mm) hex key. The post of the PM4 includes a Ø0.09" (Ø2.3 mm) through hole that enables the use of added torque when tightening.

For extra clamping support, seven additional (eight total) 6-32 (M4) tapped holes have been added for extra PM4 clamping arms (available below). This mount is equipped with six 1/4"-20 (M6) counterbores and three bottom-located 8-32 (M4) tapped holes for directly mounting the V-clamp to an optical breadboard or a post.

Clamping Arms
  • Provides Clamping Force for Our Mounts
  • Stackable 6-32 (M4) Threads on Top and Bottom of Post
  • PM3(/M): Holds Optics up to 0.97" (24.6 mm) Tall
  • PM4(/M): Holds Optics up to 1.61" (40.9 mm) Tall

Thorlabs' PM3(/M) and PM4(/M) Clamping Arms use a nylon-tipped setscrew to secure objects in our mounts and V-clamps. The PM3(/M) provides vertical travel of up to 0.97" (24.6 mm) and features a 0.69" (17.5 mm) long clamping arm. In contrast, the PM4(/M) provides vertical travel of up to 1.61" (40.9 mm) and features a 1.16" (29.3 mm) long clamping arm.

The clamping arm is held to the post using a flexure mechanism that locks with a 5/64" (2 mm) balldriver or hex key. The post includes a Ø0.09" (Ø2.3 mm) through hole that provides added torque when tightening down the post.

The PM3(/M) clamping arm can be used to hold 1" (25.4 mm) tall optics with the addition of a second post. Without the second post, the top surface of the clamping arm will be positioned above the top of the post, causing less-than-full engagement of the flexure mechanism.
