LBTEK V-Clamp is commonly used for holding cylindrical optical or mechanical components. The V-Clamp HM-V25 can hold cylinders with diameters ranging from 3 mm to 25 mm by adjusting the height of the CA-1 small clamping arm and the extension length of the rubber-tipped screw. The V-Clamp HM-V50 can hold cylinders with diameters ranging from 10 mm to 50 mm by adjusting the height of the CA-2 large clamping arm and the extension length of the rubber-tipped screw. Additionally, two sets of clamping arms can be installed simultaneously to enhance clamping stability. The V-Clamp HM-V76 can hold cylinders with diameters ranging from 12.5 mm to 76.5 mm by adjusting the height of the included arm and the extension length of the rubber-tipped screw. Meanwhile, the clamping arms of the HM-V25 and HM-V50 V-Clamps can be swapped left and right. The rear, left, and right sides, as well as the bottom of the V-block, feature M4 or M6 threaded holes for mounting on standard optomechanical components. The HM-V76 can be mounted on standard optomechanical components via the M6 countersunk holes on the bottom and sides. LBTEK Baseplate Clamp HM-PB5 is commonly used for holding rectangular optical or mechanical components. The clamping height can be adjusted by changing the position of the hex nut, with no limit on the clamping length range, a width range of 0–58 mm, and a height range of 0–65 mm. The U-shaped slot design of the clamping plate allows the screw to be adjusted freely based on the bottom M6 threaded hole positions. The plate center features a spring-loaded knurled hex thumb screw to ensure the clamped surface remains undamaged. The base plate includes M6 slots, M4, or M6 threaded holes for mounting on standard optomechanical components such as breadboards or bases.
