Horiba recalls custom configured fluorescence instruments due to a laser safety defect that may allow class 4 laser beams to burn through plastic caps.
HORIBA custom configured fluorescence instrument has a laser safety defect. This custom configuration of the modular Instrument removed the primary light source and the excitation monochromator. A plastic cap was installed to plug the optical port, where a more durable beam stop should have been used. The defect may allow the class 4 laser beam to burn (or transmit) through the plastic cap to exit the protective enclosure.
Horiba is recalling custom configured fluorescence instruments (Fluorolog-QM) because a plastic cap was installed instead of a durable beam stop, which could let high-power laser beams exit the enclosure and cause burns.
The instrument's custom configuration removed critical safety components, replacing them with a plastic cap that can't block class 4 laser beams. This allows the laser beam to burn through the cap and exit the enclosure, potentially causing skin burns or eye damage.
Users of Horiba's custom configured Fluorolog-QM fluorescence instruments are affected. Lab technicians and researchers using these instruments are most at risk.
Check for Horiba's custom configured Fluorolog-QM instruments. These were sold as modular fluorescence instruments with a plastic cap on the optical port instead of a durable beam stop.
Inspect the optical port for a plastic cap instead of a durable beam stop.

Check the optical port for a plastic cap instead of a durable beam stop. If found, stop using it immediately and contact Horiba for guidance.
