Laser power measurements

From Macken Instruments

Macken Instruments began 37 years ago as a pioneer in laser test
equipment. From the beginning, Macken Instruments has focused on
reliable, accurate, and easy to use equipment.
Analog laser power probes
Each power probe is a self-contained unit consisting of an absorbing head, a temperature
measuring mechanism, a zeroing knob and a readout dial. In operation, the dial is
zeroed. Then the absorbing head on the end of the Power Probe is exposed to the laser
beam, the average laser power can be read out on the dial. The process takes about one
minute. If it necessary to make several power measurements in succession, the absorbing
head can be rapidly cooled by immersing in a beaker of water between measurements.
LIGHT & LASERS • Conveniently size of absorbing head
Features:
• One minute to make a laser power measurements
• Very tough absorbent coating
• Easy zero adjustment mechanism
• Long-life all-metal construction
Digital laser power probes
Our digital laser power probes is a completely portable, easy-to-use calorimeter type
power meter. The instrument consists of two components: a microprocessor-based digital
meter and a probe head.

Features:
• Measures laser power from 20 W to over 11 kW
• Increased accuracy due to the microprocessor control and a digital readout
43 • Readings are retained until the meter is reset
• Inexpensive and easily switched Power Probes
