Touchscreen Portable Laser Power Meters
• Small Portable Design with Touchscreen Display
• Computer and Software Not Required
• High Damage Threshold
Touchscreen Portable Laser Power Meters feature LCD displays with touchscreen controls, the ability to adjust
wavelength, brightness and screen orientation, and min/max display. Available in two designs, one as a silicon
based sensor and the other an absorber, these portable power meters can transfer data to a computer for data
logging via a mini USB port. The silicon sensor model (#34-514) features a folding body design with a click stop
at 90 degrees, providing the unique ability of being placed on an optical table unmounted when oriented at 90
degrees. If the beam height is 78 mm off the optical table, you can simply set the folded power meter directly
onto the table. Both Touchscreen Portable Laser Power Meter models feature 8-32 mounting holes for table top
mounting and rechargeable battery. Note: Mini-USB cable not included.

Coherent® PowerMax Wand
• High Sensitivity Silicon Photodiode
• Slim Profile
• Ideal for CW or Pulsed Laser Measurements
The Coherent® PowerMax Wand utilizes a high-sensitivity silicon photodiode for continuous wave or pulsed laser
measurement from the ultraviolet to the infrared. The Coherent® PowerMax Wand is ideal for power measurements
from 8,5 μW to over 140 mW depending on the laser wavelength, and for pulsed lasers greater than 50pps.
This USB-powered laser measurement device utilizes spectrally calibrated filters to attenuate the laser beam,
allowing for a higher average power measurement than is typically possible with a photodiode.
