Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress
ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in
the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect
device reliability.

Laser Safety
This product meets the appropriate standard in Title 21 of the Code of Federal Regulations (CFR). FDA/CDRH Class 1M laser
product. This device has been classified with the FDA/CDRH under accession number 0220191. All versions of this laser are
Class 1M laser product, tested according to IEC 60825-1:2007 / EN 60825-1:2007. An additional warning for Class 1M laser prod-
ucts. For diverging beams, this warning shall state that viewing the laser output with certain optical instruments (for example,
eye loupes, magnifiers and microscopes) within a distance of 100 mm may pose an eye hazard. For collimated beams, this
warning shall state that viewing the laser output with certain optical instruments designed for use at a distance (for example,
telescopes and binoculars) may pose an eye hazard.
Wavelength = 1.5 µm.
Maximum power = 30 mW.
Caution: Use of controls, adjustments and procedures other than those specified herein may result in hazardous laser radiation exposure.
