STW (Shanghai) Electronic Technology Co., Ltd. (stock abbreviation: STW, stock code: 688213) has launched two new high frame rate industrial array CMOS image sensors, SC235HGS and SC135HGS, with 2MP and 1.3MP. These two chips are equipped with innovative SmartGS ®- 2 Plus technology has three major performance advantages: high imaging performance (high sensitivity, high quantum efficiency, low noise), high-speed (high frame rate, high shutter efficiency), and high dynamic range. As the latest products in the industrial grade machine vision application series of STW, SC235HGS and SC135HGS can be widely used in industrial detection scenarios, ensuring distortion free imaging and high-speed image acquisition performance, bringing more accurate and efficient visual detection, quality control, and production optimization capabilities to industrial cameras, helping to 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. CMOS image sensors, as the core components of machine vision, are widely used in industrial detection, recognition, measurement and other scenarios. According to Yole‘s prediction, the industrial CIS market will maintain rapid growth in the next four years, with a market size of 1.177 billion US dollars by 2027.
Advanced SmartGS ®- Supported by 2 Plus technology, creating highly reliable 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 level machine vision application scenarios such as detection, recognition, sorting, etc. They have obvious advantages in eliminating motion blur and improving image quality.
SC235HGS and SC135HGS adopt the innovative SmartGS of STW ®- 2 Plus technology, based on global shutter technology and backlit pixel structure design, brings higher sensitivity and better quantum efficiency (QE), and applies High Density MIM (HD MIM) technology, greatly reducing random noise and improving image quality. SmartGS ®- With the support of 2 Plus technology, the SC235HGS and SC135HGS are based on a smaller 3.45 μ M pixel size, achieving a 4.0 level performance compared to the previous generation μ M products have better imaging performance.
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 rapidly moving parts, achieve high-quality image capture in low illumination environments, and improve production efficiency.
• High sensitivity
Combining STW‘s unique SFCPixel ® Patented technology, SC235HGS and SC135HGS chips have a sensitivity of up to 13490mV/lux * s, which can capture bright and clear images even in nighttime or low light environments, enabling industrial machine vision applications to capture objects more accurately, improving scanning accuracy and reliability.
• High QE
On SmartGS ®- With the support of advanced 2 Plus technology, the peak quantum efficiency (peak QE) of SC235HGS and SC135HGS can reach 90%, an increase of about 7% compared to previous generation technology products. Even in low light industrial environments, the high QE performance of new products can still help machine vision cameras accurately detect and measure targets, efficiently solving the problem of automated assembly line visual information collection.
• Low noise
With the innovative ultra-low noise peripheral reading circuit technology of STW, SC235HGS and SC135HGS have achieved better noise suppression and further optimized the imaging performance of the product at high temperatures. At 16 times gain, the fixed noise (FPN) of SC235HGS and SC135HGS is as low as 2.03e -, which is significantly reduced by about 77% compared to previous generation technology products. In addition, both chips achieved PRNU as low as 0.62%, and the dark current (DC) was as low as 350e/s in an 80 ° C environment, which was reduced by more than 26% and 39% respectively compared to the previous generation technology products. This not only brought clean and detailed imaging effects with low noise, but also improved the imaging performance of the new product at high temperatures.
Supports high frame rate mode to create high-precision industrial imaging systems 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 is constantly increasing.
On SmartGS ®- With the support of advanced 2 Plus technology and high frame rate design, the SC235HGS and SC135HGS have excellent shutter efficiency (PLS increased to>40000), and support frame rates of up to 130fps and 160fps respectively, greatly improving the collection speed and stability of image sensors. This helps the image collection system achieve real-time monitoring and analysis in industrial machine vision applications, ensuring the excellent rate of factory production line products with high speed and precision Capacity and 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 changing backgrounds, resulting in more accurate images.
SC235HGS and SC135HGS have implemented HDR imaging without motion artifacts under a global shutter architecture, allowing for flexible adjustment of exposure in a single frame image, presenting rich details of dark and bright parts, effectively expanding the dynamic range of the image (reaching over 90dB). It can be better applied to detection environments such as uneven lighting 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 STW, said, "The rapid development of artificial intelligence technology is creating favorable development conditions and technological environments in various industries, and is increasingly becoming a driving force for productivity upgrading. Especially in the industrial field, more and more manufacturing enterprises are using machine vision systems for automated testing to improve efficiency and reduce costs, thereby achieving maximum production efficiency.
