Source: laservision USA Understanding Eye-safe Lasers Eye-safe Lasers: Ensuring Safety in Laser Applications What Makes Lasers Eye-safe? Lasers with emission wavelengths longer than ≈ 1.4 μm are often referred to as “eye-safe” because their light is strongly absorbed in the eye’s cornea and lens, preventing it from reaching the sensitive retina. This characteristic makes lasers […]
