Blue filter for Color compensation（IEC series）Optical filters
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.
Color compensation for digital cameras and cell phones with cameras
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.
■IR cut off filｔer for CMOS sensor IEC-K series is best for IR cut off filter.IR cut off filter is used with camera CMOS sensor to prevent a reduction in imaging quality. IEC has good high moisure resistance and meet a wide variety of customer's needs.
- 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.
