The B+W 830 IR filter blocks the entire visible spectrum. It allows 1% of light through at 800 nm, increasing to 88% at 900 nm and above.
The IR filter that blocks visible light up to 800 nm is a type of optical filter used to block visible light and IR radiation with wavelengths up to 800 nm. This filter is a crucial component in a variety of technical applications, including photographic equipment, image and video production, and research in physics and chemistry.
IR filters that block visible light up to 800 nm are often used in photographic equipment to block visible light and only allow IR radiation to pass through. This is particularly useful in landscape and architectural photography where photographers want higher contrast and sharpness in their images. IR filters can also be used to take pictures of objects that are not visible in the visible spectrum, such as infrared heat patterns.
In image and video production, IR filters that block visible light up to 800 nm are used to enhance image and video production in areas with high brightness. This filter can be used to reduce glare and enhance the sharpness and contrast of the images and videos.
In physics and chemistry research, IR filters that block visible light up to 800 nm are used to isolate and study the spectral properties of materials and molecules. This filter can be used to block visible light and only allow IR radiation to pass through, enabling the isolation of the specific wavelength of IR radiation that is of interest to the researchers.
There are different types of IR filters, each designed to block a specific wavelength. IR filters that block visible light up to 800 nm are one of the most common types of IR filters, but there are also IR filters with shorter and longer wavelengths. The choice of IR filter depends on the specific purpose and the range of IR radiation that needs to be blocked.
In summary, IR filters that block visible light up to 800 nm are an essential component in many technical applications. By blocking visible light and only allowing IR radiation to pass through, this filter can be used to enhance image and video production, isolate and study the spectral properties of materials and molecules, and take pictures of objects not visible in the visible spectrum.
