Handheld barcode scanners have become an integral part of many businesses and industries today. They help in streamlining operations, minimizing errors, and enhancing efficiency. While there are various types of barcode scanners available, laser barcode scanners are particularly popular for their precision, quick response time, and reliability. However, not many are aware that these laser barcode scanners fall under certain laser classifications. In this article, we'll delve into which laser classification most handheld barcode scanners fall under and why it matters.

A Brief Overview of Laser Barcode Scanners

Equipped with a laser diode to read the reflectance of the bars and spaces in a barcode, laser barcode scanners offer unmatched accuracy and read range. They can read barcodes from a greater distance than other types of scanners, a feature that's instrumental in many commercial and industrial applications. These scanners use a light source and lens to illuminate the barcode and capture the reflection, which is then converted into data.

Understanding Laser Classifications

Laser classifications were established by the Center for Devices and Radiological Health (CDRH), a branch of the U.S. Food and Drug Administration (FDA), and the International Electrotechnical Commission (IEC). The classification system ranges from Class 1 to Class 4 with increasing potential for hazard.

Class 1 lasers are safe under all conditions of normal use, while Classes 2 and 2M could potentially cause harm if direct eye contact is made. Class 3 lasers can cause harm in direct or specular (mirror-like) reflection, and Class 4 lasers present a higher risk that includes potential for harm from diffuse reflection and even fire hazard.

Laser Classification of Barcode Scanners: Class II

Barcode scanners predominantly fall into the laser Class II classification. This classification indicates that while the laser in the scanner can potentially cause harm if directly viewed, the human aversion response to bright light (the natural reaction to close or turn away from bright light) usually serves as a sufficient protective mechanism. Class II lasers emit visible light exclusively, which categorizes virtually all standard handheld barcode scanners.

Class II laser products are equipped with safety labels that include the laser classification, precautionary instructions, emission details, and manufacturer’s information.

Significance of Laser Classification for Barcode Scanners

Knowing the laser classification of a handheld barcode scanner is important for user safety and regulatory compliance. While the normal operation of these devices does not pose a threat to safety, knowing the potential risk can enable appropriate precautionary measures.

Moreover, compliance with FDA and IEC laser safety standards assures customers of the product quality and safety. It also prevents businesses from violations and penalties associated with non-compliant laser products.

Barcodes and Beyond

Handheld laser barcode scanners have revolutionized the way we track and manage products in various sectors, including retail, healthcare, logistics, and more. Understanding the technology driving these devices, including their laser classification, not only reveals the intriguing science behind everyday technologies but also emphasizes the importance of safety regulations in technological advancements.

In this era of fast-paced technological development, barcode scanners serve as a testament to the beneficial intersection of science, safety, and commerce. The Class II laser designation of most handheld scanners ensures optimal functionality tied with the assurance of safety. As we continue to innovate and push the boundaries of technology, maintaining this delicate balance remains critical.
