The VK250(/M) post-mountable V-clamp is ideal for holding small (Ø250 µm to Ø2.5 mm) cylindrical objects and GRIN lenses. Its compact design makes the VK250(/M) ideal to use in situations where space or access is limited. When combined with an XYZ translation stage, it can be utilized to position small micro-optics. The steady, spring-loaded stainless steel blades make this miniature clamp very easy to load, and ensures stability when positioning micro-optics for assemblies. It can be mounted directly to our Ø1/2" Posts using the rear 8-32 (M4) mounting hole, as seen above and to the left.

Do you have slightly large one that is compatible with lens with 5.32 diameter? Or could you suggest something else for me to hold this lens?

Hello, thank you for contacting Thorlabs. We do not offer this product for larger optic diameters. That being said, our VH1 miniature V-clamp mount would work perfectly for such an application.
