This weak light filter uses a unique technology to automatically attenuate light with a specific intensity, while light with a specific intensity is efficiently transmitted. This filter is a broad-spectrum response filter that does not rely on wavelength selection characteristics. A single lens can be used for overload protection of sunlight or lasers in a wide spectral range. Can be used for night vision devices, high-sensitivity photosensitive devices, and other optical equipment that requires protection.
This strong light protection filter can automatically attenuate laser and sunlight with light intensity greater than a specific value, and pass through weak light without attenuation. It is an excellent solution for precision optical instruments, high-sensitivity cameras, high-sensitivity receivers, and many other applications that require strong light protection.
