1/1.8″ series scanning lenses is designed for 1/1.8″ imaging sensor, such as IMX178, IMX334. The IMX334 is a diagonal 8.86mm CMOS active pixel type solid state image sensor with a square pixel array and 8.42M effective pixels. This chip has low power consumption. High sensitivity, low dark current and no smear are achieved. This chip suitable for surveillance cameras, FA cameras, industrial cameras. Number of recommended recording pixels: 3840(H) *2160(V) approx. 8.29Megapixel. And Unit cell size: 2.0μm(H) x 2.0μm(V).

ChuangAn Optic’s 1/1.8″ scanning lenses with different iris (F2.8, F3.0, F4.0, F5.6…) and filter option (BW, IR650nm, IR850nm, IR940nm…), it can adapt to different requirements of depth of field and work wavelength. If the iris of stock version cannot meet your needs, we also provide the customized service.

This 1/1.8″ series scanning lenses can used on industrial scanning system, to read low-contrast QR codes on substrates such as metal plates, castings, plastics and electronic components.

Especially in industrial line identification: laser etching marking, etching marking, inkjet marking, casting marking, casting marking, thermal spray marking, geometric correction, filter correction.


A QR code (an initialism for quick response code) is a type of matrix barcode (or two-dimensional barcode). A barcode is a machine-readable optical label that can contain information about the item to which it is attached. In practice, QR codes often contain data for a locator, identifier, or tracker that points to a website or application. QR codes use four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data efficiently; extensions may also be used.

Initially, it was designed to allow high-speed component scanning. The QR code system became popular outside the automotive industry due to its fast readability and greater storage capacity. Applications include product tracking, item identification, document management, and general marketing.
