Color Correction Filter
CCF/ECM
Catalog
Code
W3112
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.
Guide
▶We can produce custom sizes, please contact our Sales Division
with your request.
Attention
▶The absorption wavelength range can not be used with high power
laser and high energy pulsed laser.
▶There is no coating on both surfaces of the filter resulting in about
a 10% transmittion loss.
▶The ECM-500 and the CCF-500 are less resistance for an outside
environment use and burn or smoke easier than the CCF-5000
over time.
