Infrared filters block all visible light letting only infrared light pass. These filters are for use on cameras that are infrared sensitive. Filters are constructed of optical precision ground and polished glass. They appear completely black to the human eye.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.

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.
