Nice note:- You'd better remove IR filters in front of CCD or CMOS sensor when using IR filters- White balance adjustment- If you don't want to do any transformation on your device, you can do some post-processing after shooting to get the IR effect.In what ways will the infrared filter be used?- Archaeology, military, police officers, medical science, and detective work. Infrared filter allows normally invisible spots and visible modified elements.In which suitable light source should I use infrared filters?- IR filter can block all visible light under related wavelengths and highly sensitive to ultraviolet radiation.- 590nm, 600nm and 630nm for infrared changing machine. Rich colors, custom white balance, the original film in general, the sky was bright red, partial brown or orange, leaves of plants, blue, blue sky after post-processing saturation, yellow or yellow gold leaves.- 680nm for indoor and weak shadows use.- 750nm for indoor light use and weakness.- 760nm for cloudy outdoor at dusk and indoor brightness.Specification:Lens Material: Optical Glass.Ring material: metal.Coated Filter: N/A.To Fit: Camera, CamcorderShape: CircularLens filter size: 77 mm.Package includes:1 x 77 mm adjustable optical infrared filter.

• Infrared filters, sometimes called IR filters or heat-absorbing filters, are designed to allow medium-infrared wavelengths while blocking visible light. They are often used in light devices with incandescent bulbs (such as slides and overhead projectors) to prevent unwanted heating.
• There are also filters that are used in solid state (CCD or CMOS) video cameras to allow IR due to the high sensitivity of many camera sensors to light in the near infrared. These filters usually have a blue tint to them because they also sometimes block some of the light coming from UV light and visible from shorter wavelengths.
• Digital cameras are usually equipped with IR filters to prevent unnatural images. IR-transmission (by the way) filters, or factory removal of IR filters, are commonly used in infrared photography to let infrared light through and block visible and ultraviolet light. These filters appear black to the eye, but are transparent in with an IR sensitive device.
• The Creative Adjustable IR Filter is a compact all-in-one variable wavelength filter that adjusts the amount of wavelengths with just the touch of your wrist. Index marks on the filter let you know exactly the amount of wavelengths at a glance. Giving you clear and precise shots at wavelengths depending on whether you are using. It gives you the freedom to freely create different wavelengths
• you do not have to wear a bunch of filters for shooting. Just a filter, gives you range from 530nm to 750nm freely.
