Product Description:
1) All of our filters are full size and individual. The filter is visible to the human eye as a flat black glass. The ring is flat black/silver with no markings.
2) The filter can also be used for infrared photography. Not only is the film of an infrared camera very fast, but the picture can be seen in the infrared range. You can see through clouds and can detect forged documents, normally invisible images, crime scene analysis, Kirlian photos to create dramatic photos.
3) 99% of the light seen by the naked eye is blocked, only infrared light is removed. Technically, the naked eye cannot see 100% black, but with the help of the infrared filter and the function of the camera pro, you can become magical.
4). IR filters block all visible light only passing infrared light. These filters can be used with infrared sensitive cameras. The filters are made of optically precision ground and polished glass. They appear completely black to the human eye. If you hold an 850nm filter under strong light, the light filaments will look dark. Hold a 950nm filter under strong light and the filter will look completely opaque. If you have an infrared light, the filter is great for seeing in total darkness. When you block visible light, the light gathering properties of infrared and visible light are different and cannot be correctly
Focus 5) Optical filters can be used in many covert security and surveillance applications. Using filters in conjunction with an infrared light source and an infrared sensitive camera, you can see in total darkness. Hunters looking for prey at night can use filters. Not only do the filters make it invisible to the hunter, but the animals tend to reduce movement because the infrared light carries a bit of warmth.
6) The filter can be used in baby monitoring applications. Using an infrared light source, parents can see their children in complete darkness without being bothered by light and distractions.
