Compensation Color Filter@(IEC-K series)
*Pre name is C series
IEC

This filter has better weather resistance compared to “IEC series ”. (Passed 500hr 60C degree, 90% humidity) Transmittance: Absorption starting from 500-600nm, absorbing 700-1000nm. So far we have 6 kinds of IEC-K series. Please consult us even if you need other spec filter. *We do not use fluorine.
*Patent pending (JP2004-0137135)

Color Compensation Filters (IEC series)

This filter glass has a high transmission rate specifically for the blue through green regions and a steep slope in the red region. It is generally used as a cut filter for longer wavelengths.

Applications: color compensation for digital cameras and cell phones with cameras



IEC501 (1.3MB) IEC511 (1.3MB)
IEC505 (1.3MB) IEC518 (1.3MB)
IEC508 (1.3MB) IEC578 (1.2MB)

Note: To be able to get transmission by thickness values, you must first download the file into your desktop before you can input the desired thickness.

Used to correct a light sensor's differences in sensitivity to color. Used for the autofocus function of color copiers and fully automatic cameras.


1)Tempering can be customized depending on your application.
(To improve heat resistance or high impact resistance)
Note: After the tempering process spectral characteristics may slightly shift from original one.
2)Spectral characteristics shown on this website are nominal values. The transmission curves can be calculated for a given thickness and are for reference purpose only.
3)Spectral characteristics shown here are measured at room temperature (25degrees C, 50% relative humidity)
4)Please consult us about applications and ambient condition.
