Safety & Operation Notes
Operate the equipment only in well-ventilated environments between 10℃ and 35℃; do not block cooling air vents.
Never look directly into the laser output port. Wear 1550nm IR laser safety goggles during operation.
Do not sharply bend or pull the SMA905 output fiber cable with force.
Power the laser with stabilized 24V DC power supply; voltage fluctuation shall not exceed ±10%.
Store the laser in dry and dust-free environment to prevent moisture and dust from entering the laser cavity.
More information about the applications:
The application is absorption testing of coatings. Customers use the laser for generating a thermal lens on the test sample. This thermal lens is measured to calculate the absorption.
