Class 4 labels

Labels on this page are intended for manufacturers and sellers of Class 4 lasers emitting visible beams 500 milliwatts or more.

These labels are copyright free, and are free to use or modify. Be sure any modifications conform to laws in the area where the laser will be sold and/or used. The top part of the label (yellow triangle, Class designation, and red eye hazard warning) conforms to IEC 60825. However you can replace this with any other label format which is legal in your area; see examples here.

Generic Class 4 Laser Safety Facts labels (diode laser only, 2 watts or less)

We have created generic labels for a Class 4 diode laser covering any power between 500 and 2000 milliwatts (2 watts), and any visible wavelength. There are three versions:

For these generic labels, all a manufacturer has to do is add their name, country, and contact info (website or phone) at the bottom. Note: These particular labels are only valid for visible-beam lasers emitting between 500 and 2000 milliwatts. If you need labels for Class 4 lasers with other powers, divergences or specifications, contact us.

This is a sample of the Class 4, 0.5 mrad version. We also have 1.0 and a 1.5 mrad versions. See above for links to the full-size labels.

If possible, it is better to create a specific label. This would

State the laser type at the top, such as “Diode Laser Pointer” or “DPSS Laser Projector”
State the actual wavelength of the laser. Note that this could also change the Visual Interference (glare) distances, because they are currently calculated for a worst-case green beam.
State the actual output power; for example, if the laser only emits 800 milliwatts. Note that this would reduce both the Visual Interference distances and the Eye Injury distances.

PLACEMENT: If possible, put this Laser Safety Facts label on the laser device. However, if the laser product is small, you can use one of the small labels (below) on the product itself. The Laser Safety Facts label shown above would still be used as follows:

On outer (retail) packaging. Consumers can see this at the point of purchase.
On marketing material such as a website or brochure. Again, this allows consumers to see this information before purchase.
As a temporary label on the device (if the device is large enough) or a "hang tag" on the device. This is similar to an EnergyGuide sticker on appliances, or the pricing information on a new car's window. It can be read at time of purchase, and can later be removed.
As information in the user manual.

PRINTED SIZE: The type should be 7 points or larger. If the black bars are 2.5" wide, the type is approximately 7 points in size. This ensures that the text is readable, and that the QR code is sized for reliable scanning.

Small Class 4 product label, intended for handheld and portable visible-beam lasers

These labels are intended to be permanently affixed to any Class 4 laser with a visible beam that could be aimed at aircraft (e.g., portable, battery-powered devices). If the Class 4 laser product is large enough, it is preferred to use the full-size Laser Safety Facts label above.

This version modifies the IEC 60825 label slightly, to add the QR code plus a warning to never aim lasers at aircraft. Choose the format that fits best onto your laser and/or packaging, while remaining readable.The printed size should allow the QR code (printed part, not including white border) to be at least 1/2 inch (13 mm) wide. This ensures it can be read under normal conditions.

Depending on regulations in your country, the laser product may also need other information on a label such as power, wavelength, manufacturer, etc. Consult your country’s regulatory authority for more information.

Small Class 4 product label, intended for non-outdoor and non-portable visible-beam lasers

These labels are intended to be permanently affixed to Class 4 visible-beam lasers that are not likely to be used outdoors or otherwise aimed at aircraft. They do not contain the warning about aiming at aircraft. If the Class 4 laser product is large enough, it is preferred to use the full-size Laser Safety Facts label above.

This version modifies the IEC 60825 label slightly and adds the QR code. Choose the size that fits best onto your laser and/or packaging, while remaining readable.The printed size should allow the QR code (printed part, not including white border) to be at least 1/2 inch (13 mm) wide. This ensures it can be read under normal conditions.

Class 4 - DataMatrix label

For small cylindrical lasers, a rectangular DataMatrix label is preferred. This is to help reduce problems caused by the label curving around the laser. (See this page for more details.)

The label below is for a Class 4 laser. The text underneath is important. It gives an alternate way of accessing the laser safety information -- by typing in the webpage URL. In addition, having the text underneath indicates that the barcode is for the user’s purpose, not the manufacturer’s.
