Security application field

Ultra strong filtering infrared chip package imported from abroad, ultra strong infrared filter film plating process on the chip surface, completely filtering infrared interference, no need to increase the casing and filter, effectively filtering the impact of infrared emission light reflection in security products. High precision and good consistency: the precision of the chip is selected in the early stage, and the subsequent production process is strictly managed. The batch consistency of the finished product is excellent! Compared with similar photosensitive devices, the consistency is 3-5 times higher. The minimum accuracy can be controlled to plus or minus 10%, which can fully meet the customer's demanding requirements for starting lux value. The high temperature dark current chip works at high temperature through temperature compensation technology, and its temperature resistance is twice as high as that of similar products.
