Detect dark and challenging targets using powerful emitters with high excess gain; Detect precise features with the small, bright-red LED or Class 1 laser emitter; Avoid crosstalk when mounting multiple sensors in close proximity due to the advanced crosstalk immunity algorithm
Laser safety - Wikipedia
Laser radiation safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations.
eye-safe lasers – retina, corneal injuries, erbium, thulium
Our eye-safe options include DPSS, diode (including high-power triple-junction), and fiber laser formats with single-mode and multimode beam profiles, free-space or fiber-coupled outputs, and high peak power or pulse energies for demanding LIDAR and range finding applications.
Is Your Laser Pointer Dangerous Enough to Cause Eye Injury?
Jun 22, 2018 · The greater a laser pointer's output power, the more likely it will cause serious eye injuries, burn skin and temporarily — or permanently — impair the vision of pilots, drivers or bystanders. That much is clear.
laser sources with wavelengths greater than ~1.4um are used to prevent retina damage. These wavelengths are readily absorbed by water within less delicate regions of the eye, increasing the maximum permissible exposure, and enabling safer use of higher power laser systems. Laser sources emitting near 1.5um also provide light well within
Managing Retinal Injuries From Lasers - American Academy of Ophthalmology
Mar 1, 2009 · For lasers emitting wavelengths in the “retinal hazard spectral region,” approximately 400 to 1,400 nm, damage is characteristically confined to the retina. In such cases, radiation is transmitted through the cornea, aqueous humor, lens and vitreous humor and is imaged or focused to a small area on the retina.
Most IREDs are emitting in the 800 nm to 960 nm range. Radiation within these wavelengths causes a thermal retina hazard and thermal injury risk of the cornea and possible delayed effects on the lens of the eye (cataractogenesis).
The Critical Role of Eye-Safe Lasers Across Diverse Industries
In the realm of medicine, eye-safe lasers have become indispensable tools for procedures involving direct or indirect interaction with the eye. Notably, in ophthalmology, revolutionary techniques like LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy) rely on eye-safe lasers to delicately reshape the cornea.
The following parts of the eye are important with regard to laser effects: The Cornea, a transparent front part of the eye, transmits most laser wavelengths except for far-ultraviolet and far-infrared radiation. The Iris, a pigmented diaphragm with an aperture (pupil) in its center, controls the amount of light entering the eye.
• Self-contained Class 1 or Class 2 modulated visible laser diode emitters permit higher gain than LEDs and extended range in opposed-mode sensing systems • Narrow effective beam provides small-object detection and precise position
