850nm is suitable for outdoor and strong light use.

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 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.

 

This filter can also be used to achieve an "X-Ray" effect. Briefly, the X-Ray effect was discovered in 1997 when Sony sold Nightshot (NiteShot) 0 Lux Handicams. Users found that if an infrared filter was added to the camera and the camera was operated in daylight, the camera could sometimes view through clothing. These filters are also sometimes called an Infrared Pass Filter, See Through Filter, X-Ray Filter or See Through Clothing Filter. This effect is most noticeable on dark synthetic fabrics.
