AIMLASER infrared lasers, available in wavelengths of 780nm and 940nm, are precise and reliable for applications requiring deep penetration and minimal scattering, such as medical treatments, telecommunications, and thermal imaging. Their longer wavelengths make them ideal for cutting, welding, and marking materials that are less responsive to visible light, ensuring efficiency in various industrial processes.
Wavelength and Visibility: Infrared lasers operate at longer wavelengths (typically 780nm to 850nm) and are invisible to the human eye, making them ideal for applications like telecommunications and thermal imaging. In contrast, red lasers, with wavelengths around 635nm to 650nm, are highly visible and commonly used for alignment, pointing, and display purposes.
Application Suitability: Infrared lasers are preferred for tasks requiring deep penetration and minimal scattering, such as medical treatments and material processing. Red lasers, on the other hand, are effective for applications needing a visible reference point, such as in industrial alignment, medical diagnostics, and nightwear sporting activities.
Material Interaction: Infrared lasers excel in cutting, welding, and marking materials that are less responsive to visible light, ensuring high efficiency in industrial processes. Red lasers are better suited for tasks involving materials with high reflectivity at longer wavelengths, providing clear and precise reference points.
Understanding CDRH Classes: The Center for Devices and Radiological Health (CDRH) classifies lasers into different safety classes based on their potential for causing harm. Class I lasers are the safest, with no risk of eye damage under normal use, while Class IV lasers are the most powerful and can cause severe eye and skin injuries. Knowing the class of an infrared laser helps in assessing its safety and suitability for the specific application.
Application Requirements: Choose the CDRH class based on the specific needs. For medical applications like non-invasive imaging, a Class I or II infrared laser is typically sufficient and ensures patient safety. For industrial applications such as cutting or welding, higher power Class IIIb or IV lasers may be necessary to achieve the desired performance, but they require stringent safety measures.
Safety Considerations: Always prioritize safety when selecting an infrared laser. Ensure that appropriate protective gear, such as safety goggles, is used, and that the laser system includes safety features like interlocks and warning labels. Proper training for operators is also crucial to prevent accidents and ensure compliance with safety regulations.
