The 24th China International Optoelectronic Exposition (CIOE 2022) will be held grandly in Shenzhen from September 7 to 9, 2022. As a leading fully domestic Chinese manufacturer of wafer-level optical microlenses, Suzhou SUNA Optoelectronics Co., Ltd. (hereinafter referred to as Suna Optoelectronics) will showcase its full range of products at Booth 6B808, Hall 6 of the Information Communication Exhibition. The product lineup includes silicon lenses, fused silica lenses, silicon-based micro-grooves/heat sinks/platform microlens arrays (MLAs), as well as complete series of detectors and lasers.

Founded in 2014, Suzhou Suna Optoelectronics Co., Ltd. leverages the technological advantages of the Chinese Academy of Sciences. With the corporate vision of becoming the "China Core for Optical Communications and Optical Sensing," the company is committed to developing domestic chips with independent intellectual property and core competitiveness — breaking foreign monopolies, overcoming critical technological bottlenecks, and achieving high-end chip localization.
Suna's products sit at the uppermost tier of the optical communications industry chain. Its product portfolio includes silicon lenses, fused silica lenses, silicon-based heat sinks and micro-grooves, and InGaAs lasers and detectors. Among these, wafer-level microlens chips are the company's core product, serving over 130 domestic and international customers. Beyond optical communications, SUNA's wafer-level microlens chips are also widely used in LiDAR, non-contact temperature measurement (consumer electronics), automotive micro-projections (such as welcome lights), optical encoders (grating scales), and other applications, with mass shipments already delivered to leading manufacturers across these sectors.

SUNA currently employs over 130 people, including nearly 40 PhDs and master's degree holders with extensive experience in the semiconductor industry. The company owns its proprietary chip R&D and production lines, featuring 2,000㎡ of specialized cleanroom space (Class 100 and Class 1,000), and over 300 sets of semiconductor processing and testing equipment. These capabilities cover the entire chip manufacturing chain, including photolithography, etching, metal deposition, coating, thinning, polishing, dicing/scribing, screening, sorting, performance and reliability testing. The company has an annual chip production capacity of over 100 million units.
