Smartway (Shanghai) Electronic Technology Co., Ltd. (stock abbreviation: Smartway, stock code: 688213) has launched two new high-frame-rate industrial area-scan CMOS image sensors—SC235HGS and SC135HGS—2MP and 1.3MP. Equipped with the innovative SmartGS®-2 Plus technology, these two chips have three performance advantages: high image performance (high sensitivity, high quantum efficiency, low noise), high speed (high frame rate, high shutter efficiency), and high dynamic range. As the latest products of Smartway's industrial-grade machine vision application series, SC235HGS and SC135HGS can be widely used in industrial inspection scenarios, ensuring distortion-free imaging and high-speed image acquisition performance, bringing more accurate and efficient visual inspection, Quality control and production optimization capabilities help improve the efficiency and quality of industrial production.


With the increasing demand for intelligence and automation in the industrial field, machine vision technology has become an important means to improve production efficiency and quality. As the core component of machine vision, CMOS image sensor is widely used in industrial detection, identification, measurement and other scenarios. According to Yole's prediction, the industrial CIS market will maintain rapid growth in the next four years, and the market size will reach US$1.177 billion by 2027.




Supported by advanced SmartGS®-2 Plus technology, it creates high-reliability visual inspection applications with stronger performance


With high measurement accuracy and real-time imaging visual data acquisition capabilities, global shutter sensors are widely used in various industrial-grade machine vision application scenarios such as detection, identification, and sorting, and have obvious advantages in eliminating motion blur and improving image quality.


SC235HGS and SC135HGS adopt SmartGS®-2 Plus technology of Smartway, based on global shutter technology and back-illuminated pixel structure design, which brings higher sensitivity and better quantum efficiency (QE), and applies High Density MIM (HD MIM) process greatly reduces random noise and improves image quality. With the support of SmartGS®-2 Plus technology, SC235HGS and SC135HGS achieve better imaging performance than the previous generation of 4.0μm products based on the smaller 3.45μm pixel size.


The SC235HGS and SC135HGS image sensors with high sensitivity, high QE, and low noise can greatly improve the detection ability of professional machine vision applications for fast-moving parts, realize high-quality image capture in low-light environments, and improve production efficiency.


• high sensitivity


Combined with Smartway's unique SFCPixel® patented technology, the sensitivity of SC235HGS and SC135HGS chips is as high as 13490mV/lux*s, which can capture bright and clear images even at night or in low-light environments, making industrial machine vision applications more Accurately capture objects, increasing the accuracy and reliability of your scans.


• High QE


With the support of SmartGS®-2 Plus advanced technology, the peak quantum efficiency (peak QE) of SC235HGS and SC135HGS can reach 90%, which is about 7% higher than the previous generation technology products. Even in a low-light industrial environment, the high QE performance of the new product can still help machine vision cameras accurately detect and measure targets, and efficiently solve the problem of automatic assembly line visual information collection.


• low noise


With the help of Smartway's innovative ultra-low noise peripheral reading circuit technology, SC235HGS and SC135HGS achieve better noise suppression and further optimize the imaging performance of the product at high temperatures. The fixed noise (FPN) of SC235HGS and SC135HGS is as low as 2.03e- under 16 times gain, which is about 77% lower than the previous technology products. In addition, both chips achieved a PRNU as low as 0.62%, and the dark current (DC) was as low as 350e-/s at 80°C, which was reduced by 26% and 39% respectively compared with the previous generation technology products More than %, not only brings clean and detailed, low-noise imaging effect, but also improves the imaging performance of the new product under high temperature.




Support high frame rate mode, create a high-precision industrial imaging system at a faster speed


The frame rate of industrial cameras determines the measurement efficiency of equipment, so in order to make industrial production more convenient and efficient, the demand for high frame rate image sensors has been rising all the way.


With the support of SmartGS®-2 Plus advanced technology and high frame rate design, SC235HGS and SC135HGS have excellent shutter efficiency (PLS increased to >40000), and support frame rates up to 130fps and 160fps respectively, which greatly improves the performance of image sensors. Acquisition speed and stability help the image acquisition system realize real-time monitoring and analysis in industrial machine vision applications, and guarantee the high-quality rate, production capacity and fineness of factory production line products with high speed and high precision.




Not afraid of light interference, HDR function improves industrial detection accuracy


Industrial machine vision cameras often need to face complex and harsh operating environments. CIS equipped with high dynamic range (HDR) function can capture more details and textures in low light, high contrast or strong light changes, thus producing more accurate image.


SC235HGS and SC135HGS realize the HDR imaging function without motion artifacts under the global shutter architecture, and can flexibly adjust the exposure in a single frame image, thereby presenting rich details in dark and bright parts, and effectively expanding the dynamic range of the image (reach above 90dB). It can be better applied to detection environments such as uneven illumination or extreme brightness, greatly improving the accuracy and reliability of detection, and helping to improve production efficiency and quality control.


Ms. Zhang Peiling, Chief Marketing Officer (CMO) of Smartway, said: "The rapid development of artificial intelligence technology is creating favorable development conditions and a technological environment in all walks of life, and it is increasingly becoming a driving force for productivity upgrades. Especially in the industrial field, more and more More and more manufacturing companies use machine vision systems for automated inspections to improve efficiency and reduce costs, thereby maximizing production benefits.


As early as 2018, Smartway began to embrace the new blue ocean of machine vision, forward-looking layout of professional-grade industrial sensor subdivision track, driving product innovation with technology, helping customers to create stronger product competitiveness, and continuously improving market advantages. We will continue to give full play to our own advantages, and use cutting-edge machine vision CMOS image sensor technology to help enterprises improve quality, reduce costs, and increase efficiency, and provide strong support for the manufacturing industry to move towards high-quality development.
