Why pay several hundred bucks for a beam expander, when you can buy a silver Daisy rifle scope for under $20.00? The main tube takes CR123A's perfectly. It has all glass optics. The aperture lens housing is finely threaded for highly accurate and stable focus length adjustments. Don't settle for a 'needle' beam, when you can get 5/8" beams at aperture and much further range with one 'Daisy' of a long distance lightsaber!
I'm working on adding digital diode temperature display as there is no active cooler on this unit.
