Some details of UV Longpass Filters china
UV Longpass Filters china is a bandpass filter that allows light of a certain bandwidth near a certain wavelength of ultraviolet (wavelength less than 400nm) to pass through, and light in other ranges is cut off.
Refers to the absorption of ultraviolet light, also known as the anti-fog filter. Due to the scattered state of ultraviolet rays in the atmosphere, for long-range photography on sunny days, the fog that is invisible to the naked eye appears, causing the photos to become dull. The filter used to intercept this harmful ultraviolet light is UV Longpass Filters china. Both black and white photography and color photography can be used without exposure multiple. As another use of UV Longpass Filters china, it can be used to protect the lens.
With ultra-high cut-off background depth, it can greatly improve the system signal-to-noise ratio.
Most UV Longpass Filters china are packaged in a black anodized aluminum housing with a logo printed on the housing, and the arrow mark represents the transmission direction of light inside the filter.
