 RLI Capabilities and
Experience
Rockwell Laser Industries is an industry leader in laser safety. This includes knowledge and experience in the measurement aspects related to laser
safety. Utilizing these abilities, RLI regularly assists clients with laser output measurements using RLI output measurement and beam analyzer systems to
quantify the client's measurement requirements.
For more information regarding this service, please contact us via email or call a consulting
representative at 1-800-94-LASER.
The ANSI Z136.1 STANDARD FOR SAFE USE OF LASERS, FDA/CDRH Laser Product Performance Standards and International (IEC 825)
standards are the basis of the measurements. The measurement capabilities include:
- Power, Pulse Energy
- Pulse Duration and Response Rate
- Laser Beam Profiles
- Near Field or Far Field Beam Divergence
- Diameter of Focused Beams
- Diameter of Gaussian Beams (1/e and 1/e2)
- Shapes: Elliptical, Rectangular, Others
- Near Gaussian Beam Profiles with M2
Note that the specific method in making the measurements for the above items will be chosen for each
measurement situation.
Qualified Testing for Third Party Certifications
RLI has been qualified by a major international testing laboratory as a subcontractor for the measurement of laser beams and the testing
of laser products for conformity to international laser standards. Such measurements and testing are often required by manufacturers to meet
all requirements for CE marketing of products for the European market.
Test Methods and Reference Sources
The measurements will be conducted following an overall assessment by RLI staff of the requirements for each client. All measurements
shall be done using test procedures that are considered as accepted industry practice.
Where appropriate, the following documents will serve as a reference for the measurement procedure
requirements:
