laser HEADS: are laser tubes enclosed in an aluminum housing with an internal ballast resistor and an ALDEN high voltage connector laser TUBES: do not include the housing but I will include a ballast resistor and clips to which you can solder the high voltage leads Note: the power output of each tube was measured using a Newport power meter cal'd to 632.8nm with the test aperature fully illuminated. The first reading is the initial power output and the second reading is the power output after a 20 minute warm up. MELLES GROIT * LHR 321 HeNe laser HEAD $60 3.8mW/4.5mW(20 min) * LHR 320 HeNe laser TUBE $70 4.7mW/5.5mW(20min) SIEMENS * LGR 7631 HeNe laser TUBE $45 3.7mW/4.3mW(20min) SPECTRA PHYSICS >2mw but SLOW STARTING * HeNe laser HEAD $20 * HeNe laser HEAD nice housing $25 STANDARD 1 3/4" by 15" aluminum housings great for housing your laser tube will fit above tubes front cap 1/4" aperature end cap has ballast resistor if you are willing to hack but no ALDEN conn. aluminum housing w/ 6 holes front and back * Black Anodized Aluminum $15 every other hole tapped for 10/32 plastic screw * Misc others (silver/reddish) $10 holes not tapped Will include specs on the tubes/heads and suggestions for obtaining power supplies if possible. Payment cash, money order, or check + $3 shipping. Will sell first come first served determined by email date. I will be gone for two weeks and will reply as soon as I return. -- ------------ Jim Skrentny University of Wisconsin Computer Systems Lab office 608-262-6606 (afternoons), home 608-251-5683 USENET: ...!{allegra,heurikon,ihnp4,seismo,ucbvax}!uwvax!skrentny ARPA INTERNET: skrentny@cs.wisc.edu
