Product introduction | ||||||||
Neutral density filters use the absorption or reflection characteristics of materials to attenuate the intensity of light. After the light in the visible region to the near-infrared region passes through the neutral density filter, different wavelengths are attenuated in the same proportion. This makes the optical element maintain approximately equal light energy transmittance in a wide band. | ||||||||

Linear Beam Smoke Detector:
Using the light reduction filter, the smoke diffusion can be simulated to detect fires within a fixed range around the infrared. Its working principle is to use the light reduction filter to reduce the emission of infrared emitters to Infrared receiver's light beam meter to determine the fire, this method of fire detection is often called the dimming method.
(1), ND-2: can reduce the first-level aperture and 50% of the amount of light;
(2), ND-4: can reduce 2 levels of aperture and 75% of the amount of light;
(3), ND-8: 3 levels of aperture and 87.5% of light can be reduced;
(4), ND-400: It can reduce the light quantity of 9 stops, which is suitable for long-time exposure during the day and shooting the sun.
