Space optics 2 x laser beam telescope expander units
2 BIG LASER OPTICAL BEAM EXPANDER LENS UNITS BUILT BY SPACE OPTICS RESEARCH LABORATORIES, INC
HARRY G. ARMSTRONG AEROSPACE. MEDICAL RESEARCH LABORATORY
EACH OPTICAL UNIT HAS THE ORIGINAL DEPARTMENT OF DEFENSE YELLOW STICKER UNDER THE BASE ON EACH ONE.
I HAVE A LOT OF EQUIPMENT FROM THE DEPARTMENT OF DEFENSE AND MOST EQUIPMENT HAS THESE YELLOW STICKERS ON THEM, I HAVE SEVERAL PARTS FROM THE ATLAS SPACE ROCKET ICBM (INTERCONTINENTAL BALLISTIC MISSILE) AND THOSE PARTS HAVE THE SAME STICKERS.
THE FOLLOWING LIST IS THE DATA FROM THE YELLOW DOD LABEL.
THE DATA FROM THIS STICKER CAN BE PUNCHED INTO A COMPUTER BY A PERSON WHO HAS THE ACCESS AND CLEARANCE TO THE SPECIFIED DATA BASE, IT MAY NOT REVEAL WHAT THE UNITS WERE USED FOR AND HOW BUT WILL STATE FOR INFO FOR THOSE WHO ARE CONCERNED WITH GETTING MORE INFO ABOUT THE UNITS SINCE I HAVE NO DATA ON THEM.
* THESE LASER OPTICAL UNITS CAME FROM AAMRL (HARRY G. ARMSTRONG AEROSPACE. MEDICAL RESEARCH LABORATORY.)
* THE AAMRL TRACEABILITY AND CALIBRATION LABELS AND BAR CODES ARE STILL ON THE UNITS
* THESE UNITS CAME FROM A CLASSIFIED U.S AIR-FORCE SPACE PROGRAM,. THEY WILL NOT RELEASE THE DATA RELATED TO THESE UNITS WHICH IS UNDERSTANDABLE.
* THESE HIGH QUALITY OPTICAL INSTRUMENTS UNITS ARE MADE FROM BILLET MACHINED BLACK ANODIZED ALUMINUM AND ARE THREADED AND BOLTED TOGETHER, THERE ARE EXTREME FINE THREADS WHICH HOLD THE ADJUSTABLE LENS HOUSINGS.
* THE LENS CLEAR APERTURE DIAMETER IS 2 INCHES ON ALL LENSES, THE LENSES ARE A/R COATED, I AM NOT SURE WHAT WAVE LENGTH THEY ARE COATED FOR BUT THEY LOOK LIKE BROADBAND A/R COATINGS TO ME.
* THE TOTAL HEIGHT OF EACH UNIT IS ONE FOOT
* THE MAIN BODY OUTSIDE DIAMETER OF THE UNITS ARE 3.5 INCHES
* THE TOTAL LENGTH OF THE UNITS ARE 800mm
* THE UNITS ALSO HAVE ANOTHER NATO STOCK NUMBER (NSN) WHICH IS HALF MISSING, AND IS DIFFERENT FROM THE DEPARTMENT OF DEFENSE NSN YELLOW LABEL, THE NUMBERS LEFT ARE 6760L000MPLC
