Medium-gray density mirrors are also called dimming mirrors. Divided into four gears ND4, ND8, ND16, ND32 can reduce the 2-level aperture or 75% of the amount of light entering the camera, the lens will not have any effect on the color of the original object, but also can truly reproduce the contrast of the scene.

Brief description: Gray scale mirror is used to reduce the amount of light entering to achieve special exposure effects

In many cases, due to the intensity of the external light, we cannot get a long enough shutter time and cannot realize our photography intentions. For example, when shooting water in the field, we hope to use a one-second shutter to make the water present a soft cotton-like texture. However, due to the strong light, the shutter speed is still around 1/30 second even when shooting with the camera's minimum aperture and minimum iso. The only way at this time is to use one or even two ND8 lenses to attenuate the light entering the lens. ND mirror has a variety of densities to choose from, such as ND2, ND4, ND8, ND16, ND32. Among them, ND2 is to reduce the exposure by one stop, ND4 is to reduce the exposure by two stops, and ND8 is to reduce the exposure by third gear. It can also be used in combination with multiple neutral gray density mirrors.

Our non-reflective ND mirror adopts imported optical glass surface for optical coating processing, which can ensure that the light wave has a flat spectral response and is not easy to age under normal conditions. It can achieve uniform attenuation from ultraviolet to near infrared. Double-sided coating Ensure that the shooting is non-reflective, and one side is coated with a waterproof film to ensure that the shooting quality will not be affected under humid conditions. It can have the characteristics of both colored glass ND mirror and ordinary coated ND mirror. With the low reflection characteristics of colored glass, the attenuation value can be flexibly customized to different attenuation values in the range of OD0.1-OD5. The conventional sizes are: 46mm, 52mm, 55mm, 58mm, 67mm, 72mm, 77mm, 82mm, which can be customized at any time according to customer requirements.

Application areas: UAV lens, camera lens, sports equipment lens, laser equipment, etc.
