Color Correction Filter / CCF_ECM
The filter that can simulate the sensing of a human eye which is similar the silicon pixel detector sensor with a wavelength located at a peak at the NIR range. It is also widely as a filter attached to a CCD sensor.
Use the filter to correct the unnatural color taken with an IR camera.The CCF5000 can be used in natural environment or outside, the surface of the filter is tough and hard to burn.
The CCF 500 and CCF 5000 have the same characteristics until 900nm, above 900nm the transmittance is different.
The color of the ECM-500 is darker than the CCF-500 and CCF-5000 and is fit for use to cut off the NIR light.
