A: Particulates in air will diffuse laser beam reducing accuracy of measurements. The cleanroom removes particles from the air.
A: Laser cleanrooms often do experiments with lights off or with special photography red reduced lighting to make laser beam visible to operators and eliminate possible interference from room lighting.
A: Common laser cleanroom safety features include blackout curtains for windows, blackout curtains around laser area, “laser on” signs outside the cleanroom, and interlock systems cut power to laser when door is opened.
A: Cleanroom laser blackout curtains types vary depending upon type and power level of laser and laser process. Metal foil inserts are often used to increase curtain resistance to laser beam. Chain weights can be added to ensure curtain seals to cleanroom floor. Blackout curtains can be fixed or on roller track.
A: Some laser experiments are measuring nano-level differences which can be affected by temperature or humidity variations.
A: Certain medical devices and cleanroom consumables use lasers in their manufacturing practice. Common processes are laser welding and laser cutting. These manufacturing process require cleanroom environment to ensure good quality and cleanroom grade product. The cleanroom environment removes smoke and fumes that could block or disperse the laser beam. The cleanroom also help keep contamination off the laser lens.
