Fotga 40.5mm Infrared Infra-red IR Pass X-Ray 950nm Lens Filter for Sony Nikon Canon Pentax Olympus Leica Samsung Fujifilm Dslr Camera
- Infrared filters, sometimes called IR filters or heat-absorbing filters, are designed to allow IR mid-infrared wavelengths while block visible light.
- They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating.There are also filters which are used in solid state (CCD or CMOS) video cameras to allow IR due to the high sensitivity of many camera sensors to near-infrared light.
- These filters typically have a blue hue to them as they also sometimes block some of the light from the shorter visible light and UV wavelengths.
- This IR filter can block all visible light under 650nm, therefore let you experience some different shooting.
- 950nm is suitable for outdoor and strong light use.
