Our support engineers will provide professional guidance on installation, alignment, safety, and maintenance procedures.

• Invisible Radiation Warning– Some laser modules emit infrared (IR) or ultraviolet (UV) radiation that is invisible to the human eye. Never assume the laser is malfunctioning simply because you cannot see the beam. Always confirm that the power is disconnected before inspecting the module.
• Do Not Look Directly into the Laser Aperture– Even when wearing certified laser safety goggles, never stare directly into or near the beam exit of a working laser module.
• Avoid Reflected Beams from High-Power Lasers– Reflection from Class IV lasers (output power > 500 mW) can cause severe and permanent eye damage. Always wear wavelength-specific safety goggles when operating or aligning high-power laser systems.
• Keep Away from Flammable Materials– Do not place flammable or explosive items (such as paper, cloth, leather, or plastics) in the laser path. Black or dark-colored materials absorb laser energy more easily and may ignite. (Exception: controlled material-burning experiments with proper fire protection.)
• Avoid Direct Human Exposure– Class IIIa or higher lasers (≥ 5 mW) can burn skin or eyes. Never point a laser beam at any part of a person’s body.
Restrict Access to Trained Personnel Only – Keep all laser devices out of reach of untrained individuals, children, and pets.

• Never Aim Toward Glass Surfaces– Ordinary glass reflects roughly 4 % of incident light, which can redirect dangerous laser radiation into your eyes. Avoid operating lasers in front of mirrors or reflective windows.
• Working Plane Awareness– When setting up an experimental platform, note the laser emission height. Do not position your head or eyes near this level during operation. Lenses and mirrors may reflect or refract light unexpectedly. Always align optical components downward or horizontally—never angle a beam upward.
• Remove Reflective Accessories– Watches, jewelry, and other shiny objects can reflect laser light unpredictably. Remove them before use.
• Infrared Beam Detection– IR lasers (wavelength > 800 nm) are almost completely invisible. Use a beam-viewing card, IR detector, or up-conversion screen to visualize the beam path safely.
• Visual Brightness Misjudgment– Some wavelengths (below 430 nm or above 700 nm) appear much dimmer than their actual power output. Do not rely on visual brightness to judge beam intensity.
• Pulsed Laser Caution– Pulsed lasers can have extremely high peak power even at modest average power levels. Verify that all optical elements and samples in your experiment exceed the laser’s damage threshold before exposure.
• Prohibited Uses– It is strictly forbidden to point laser beams at moving vehicles, aircraft, or any area where light could distract or endanger others.
• End-of-Beam Safety Stop– Always place a black anodized or matte metal plate at the end of your optical path to absorb residual energy and prevent laser leakage into surrounding areas.

Low-Power Modules – ERDI laser modules rated below 1 mW are considered eye-safe under normal operating conditions and can be used without hazard when handled properly.

• Protective Eyewear– Always wear certified laser safety goggles designed for the specific wavelength and power level of your module.
• Appropriate Clothing– Light-colored or white long-sleeved clothing reduces the risk of heat absorption or ignition if stray laser light contacts the fabric.
• UV Laser Protection– For ultraviolet lasers, apply broad-spectrum sunscreen (SPF 30 or higher) to exposed skin areas to minimize UV radiation effects.
• Environmental Safety– Operate lasers in a controlled laboratory or industrial environment with minimal reflective surfaces. Ensure that all personnel nearby are informed of ongoing laser use and have received proper training.
