Listing is for one unit of Thorlabs part # LD3000R. Item is in manufacturers original packaging, never used. Comes with users manual. I have ten of these sealed from the factory. I opened two just to verify contents and photograph them. They are all brand new though. This listing price is for one. If you’d like to buy them all drop me a note. I can offer a small discount for buying five or more, or all of them. These are overstock from a Boston based medical company. It takes over three weeks to source them directly from Thorlabs. They charge $219.56 per unit plus shipping. I’ll have them to you much quicker and for less. Ships ASAP!

Listing price is for one unit.
