TZ3 Self-Closing Tweezers Holding a Ø1" Lens
Thorlabs offers three types of tweezers for the handling of delicate optics. Our TZ1 tweezers work well for holding the edges of Ø12 mm or smaller optics. These tweezers are made from stainless steel and have molded-carbon-fiber tips to protect the object being handled. Alternatively, our TZ2 tweezers can accommodate Ø25.4 mm or smaller optics and are made from nylon that is chemically resistant to common lab solvents. Finally, our TZ3 self-closing tweezers are able to comfortably hold the edges of Ø12 mm to Ø25.4 mm optics, as shown in the photo to the right. The TZ3 tweezers have a polyolefin cover over each tip that is unaffected by common lab solvents and helps to grip and protect optics.
This Manual Vacuum Pick-up Tool allows the user to lift and hold small optics, including Ø1" lenses and mirrors, without causing damage. Each tool comes with seven interchangable tips and one body in a convenient plastic case. To ensure a good vacuum, choose a tip with a pad that is smaller than the optic. This tool is not recommended for surfaces with steep curves, as the pad will not be able to fit flat against the surface.
Please note that using vacuum tweezers improperly can damage an optic. The metal extension tube may contact your optic if the suction cup is pressed against the optic too hard. Proper usage instructions are included with the tweezers and should be followed.
