Sony Quality Assurance Department shall analyze any product that fails during said warranty period, and if the analysis results show that the product failed due to material or manufacturing defects on the part of Sony, the product shall be replaced free of charge. Laser diodes naturally have differing lifetimes which follow a Weibull distribution. Special warranties are also available. Sony reserves the right to change products and specifications without prior notice. This information does not convey any license by any implication or otherwise under any patents or other right. Application circuits shown, if any, are typical examples illustrating the operation of the devices.

However the optical power density of the laser beam at the diode chip reaches 1MW/cm2. Unlike gas lasers, since laser diode beams are divergent, uncollimated laser diode beams are fairly safe at a laser diode. For observing laser beams, ALWAYS use safety goggles that block infrared rays. Usage of IR scopes, IR cameras and fluorescent plates is also recommended for monitoring laser beams safely. In addition, the laser diode array of this product is not protected by window glass or other covering (open package product ), so special care is necessary when handling.
