About ZOMEI 77MM 950NM Pro Quality Infrared Infra-red IR

1). Our filters are custom made using precision made ground and polished German glass. Our filters are all full size and discrete. Filter appears to the human eye as flat black glass. 2). Filters are also useful for infrared photography. Infrared camera film is not only extremely high speed, but also pictures often look quite different when viewed in the infrared range. You may be able to see through clouds, detect forged documents, see normally invisible images, crime scene analysis, Kirlian (Kirlian) photography and create dramatic pictures. 3).With the filter in place 99% of the light seen by the naked eye is blocked out and only infrared light is filtered through. Technically the naked eye cannot see 100% black but with the infrared filter and your camcorder specialist functions, you will magically be able to. 4). Filters are constructed of optical precision ground and polished glass. They appear completely black to the human eye. If you hold the 850nm filter up to a bright light, you will see the light filament faintly. If you hold the 950nm filter to a bright light, the filter will appear completely opaque. Filters are great for viewing under complete darkness if you have an infrared illuminator. Blocking visible light enables you to achieve correct focus since infrared light and visible light have different focusing characteristics. 5).Filters can be used for many covert security and surveillance applications. Using an filter in conjunction with an infrared light source and infrared sensitive camera, you can see in complete darkness.The filters can be used by hunters searching for game at night. Not only does the filter let the hunter remain inconspicuous, but the animal tends to reduce motion as the infrared light provides slight warmth. Package include: zomei 77mm 950nm IR Filter x 1
