(M)icroscope (S)lide (G)lass Lens. Anyone think of this? Over ten years ago,in Jr.High, I had to buy a box of microscope slides for science class. Box today is still full. From each slide I can make two lenses for most pocket sized flashlights.
Got em' in my Super LGI, Aitec collimator light, and a Mini-Mag so far. Very high quality lens! If you think about it, microscope slides have to be as optically pure as they can be for the obvious reasons.
I guess a downside is they are more fragile than other glass used for lenses. Mine are insulated w/ o-rings, none broken yet. Be sure to sand a good smooth edge after cutting em' out and you got yourself a inexpensive MSG lens. Chips on the edge lead to cracking.
Any comments or questions?
