Modulated Helium-Neon Laser
Laser light can be modulated by varying its intensity. This laser is capable of up to 15% intensity variations at rates up to 1 MHz. The increased brightness can also help students make better holograms. Small movement or vibrations are less likely to blur the picture with a shorter exposure time.

Features:
• Beam can modulate from 85% to 100% of full power
• Accepts modulation signals ranging from 50Hz to 1MHz
• Effective signal transmission up to several hundred feet. With collimator
and detector transmission range increases to thousands of feet
• Miniature phone jack accepts audio input signals at l00mV peak-to-peak
level and 8K ??impedance
• Two-year limited warranty
Power (mW): 1.0 min./1.5 typ./2.9 max.
Beam diameter: 0.75 mm
Beam divergence: 1.1 mRad
Power Requirements: 105-125 Vac, 50-60 Hz
Class IIIA U.S. CDRH
