Abstract

We have successfully developed an electrochromic device (ECD) as the "optical iris" of a camera lens that could potentially control the transmittance intentionally. To realize this goal, we have applied photolithography and subsequent wet etching to fabricate the patterned complementary electrochromic systems where tungsten oxide and prussian blue were electrodeposited. At this point it is important to note that such a device could be directly attached onto a camera lens without any mechanical equipment. In this way the device will reduce power consumption and will be much smaller and thinner which results would also further the miniaturization of cameras.
