IR Filter can cut-off infrared rays reached to Sensor. By attaching IR Filter to skin on lens unit or holder, it will be able to eliminate an appeared error such as flickering Image while taking a picture. Alpha Optik can process the circle and square filter with each grade of Mega Pixel (20um) and VGA (30 um) with a custom-designing.

Alpha Optik IR cut-off filter can sharply cut infrared ray.


1.There is the specialist crystal technology: from cutting, polishing, flatness technology, cleaning, coating, combining technology.

2.Angle cutting tolerance improving from +/-0.3’ to +/-0.1’; thickness tolerance improving from +/-0.05 TO +/- 0.025mm, and cutting speed improving from 1.2mm/H to 9mm/H, all by ourself-made Multi-cutting machine.

3.The flatness technology can let the 4 angle and 8 sides be polishing at the same time. And the quality can be improved about 50%;
