Not really sure if this would be good for Laser use, but there are a bunch of electronic components, and other stuff that the hobbiest could use at some pretty low prices.
Here's an amazing, top quality dichroic optical assembly at a fantastic price for those who know what to do with it or its parts. White light entering one end splits chromatically and emerges from the other with virtually no loss of intensity. The assembly includes an iris, a dichroic wheel with two color filters, an infrared filter mirror, and a rectangular quartz prism all assembled around a 60 mm aspheric lens. The whole thing would fit into a 7" x 7" x 9-1/2" box. It has got to have applications in the physics classroom for demo purposes, perhaps in the lab, too. We are guessing someone paid hundreds of dollars to have these dudes made.

If you handle electronic components, you'll appreciate these anti-static latex ESD fingercots, manufactured for use in a class-100 cleanroom. They are comfortable, powder-free, packed in gas-impermeable film with an inner and outer wrap, and immobilized to prevent charge generation. They are suggested for Class II (2000-3999V) static-sensitive devices. Or for counting stacks of filthy lucre. Or for sharing a keyboard when your sharee has a cold. Our each is a pack of (720) 3" fingercots. Not for medical use.
