Silicon inspection can be a challenging problem for silicon and semi-conductor manufacturers in terms of pattern alignment, pattern defect inspection and edge position bonding inspection. Defects do not initially affect the chip's functionality, but they do end up affecting the chip's reliability. This article discusses the use of silicon wafer inspection with SWIR cameras.
MTF is the best proxy for lens performance, but the math behind it and the graphs that depict it often obstruct understanding. This paper demystifies MTF, arming vision system decision makers with the knowledge they need about it to choose the right lens every time.
There are many factors that are important to consider when you purchase a high-speed camera. This article discusses the important considerations involved in selecting the appropriate high-speed video camera for your specific needs.
Ophir’s infrared thermal imaging lenses help provide a quick, inexpensive, and noninvasive solution for surveying crowds and identifying people with elevated skin temperature who require further investigation. They have been used effectively for the past two decades and were deployed successfully during the SARS and COVID-19 pandemics.
LASER COMPONENTS delivers spatial light modulators (SLM) as adaptive optical elements that modulate light spatially in amplitude or phase. The available devices are based on either reflective (LCOS) or translucent (LCD) liquid crystal microdisplays.
The ZeGage Pro and ZeGage Pro HR are scanning white light interferometers that provide 3-D optical surface profiling for the measurement of precision surfaces that require noncontact metrology. The base ZeGage Pro model delivers surface mapping at the nanometer scale, meeting the needs for most industrial surfaces. For smoother samples with a much finer surface finish, the ZeGage Pro HR offers more than 20X higher precision with 0.15 nm vertical precision.
The LDB/LSB Series from Sensors Unlimited generally is used for monitoring optical performance of S-, C-, and L-band channels in DWDM networks and for agricultural sorting, biomedical analysis, thermal imaging, and industrial process control.
