Thorlabs
The Thorlabs EDU-OT1 Portable Optical Tweezers Demonstration Kit (Imperial) was released on November 26, 2013, and maintained an open web presentation until its discontinuation on August 3, 2018. This discontinued educational system has been officially replaced by the EDU-OT3 model. Submit the exact part number, quantity, and application requirements to request a quote for available surplus or support options.
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Thorlabs references — within one business day.
For a faster response, include quantity, condition, and delivery destination.
