Specifications for the incandescent Light Source(Model OS-9102B) Output:Approximately 15 candlepower Filament temperature:2700K Bulb:#93,operated at 12 VDC,1.0 A;bulb life approximately 700 hours Regulation:Maximum intensity variation of 2%for a 10%change in line voltage. Input Power:105-125 VAC 60 Hz (or 210-240 VAC,50 Hz if specified when ordered) Fuse 0.5A,Slo-Blo (0.25 A for 220 VAC model) The Helium Neon Laser The helium neon laser is a 0.5 mW,TEMoo mode laser,providing randomly polarized light at a wavelength of 632.8 nm.The built-in power supply is regulated so the output has minimum ripple and the intensity is stable to within +2.5%.A 15 minute warm up is required to reach full power, but the power on start-up is greater than 0.35 mW.If you'd like more technical specifications,and a detailed explanation of laser operation,see the instruction manual that's included with the laser. *COUTION:This is a relatively safe,low power laser.Nevertheless,we strongly recommend the following precautions: Never look into the laser beam,either directly,or as it is reflected from a mirror. Set up experiments so the laser is either above or below eye level(for both sitting and standing people). To Setup the Laser using the Laser Alignment Bench: The laser is most conveniently aligned using the laser alignment bench,which can be joined to the optics bench using the bench couplers.The procedure is as follows: 1Place the optics bench and the laser alignment bench end to end,as in Figure5.Notice that only one end of the laser alignment bench has holes for two leveling screws.That is the end that joins to the optics bench. lase bench coupler Laser Alignment Bench 14-20hex ead scrov leveling screw and lock-nut bench coupler Laser Alignment Bench 1111111111171hT Top View of Bench Coupler bench couple Optics Bench Figure 5:Connecting the Laser Alignment Bench 2Remove the four leveling screws on the adjoining ends of the two benches. 66 Specifications for the incandescent Light Source (Model OS-9102B) Output: Approximately 15 candlepower Filament temperature: 2700 0K Bulb: #93, operated at 12 VDC, l.0 A; bulb life approximately 700 hours Regulation: Maximum intensity variation of 2% for a 10% change in line voltage.
