Advancing Semiconductor Inspection with UV Imaging
Light from the UV range is invisible to the human eye, but with sensitive UV imaging, sensor users can capture and visualize phenomena that generate UV radiation, giving them new opportunities and insights. UV imaging has a broad range of applications across multiple industries from scientific to industrial that include semiconductor quality inspection, electrical discharge detection, power grid maintenance, environmental UV monitoring and fluorescence microscopy.
Photonis (part of Exosens) offers ultraviolet cameras and cores and UV intensified cameras, combining long-time expertise in Image Intensifier tubes with state-of-the-art camera technology. These imaging technologies push the boundaries of what’s visible by enabling high-precision inspections through ultraviolet imaging. Designed to capture wavelengths between 190–400 nm, these UV cameras reveal microscopic defects and residues that traditional systems may miss. These capabilities are essential for maintaining the high standards required in semiconductor manufacturing. From wafer surface analysis to inline defect detection and layer thickness measurement, Photonis offers advanced imaging solutions tailored for the industry’s most critical applications.
The iNocturn and i2Nocturn series provide intensified imaging performance, supporting reliable, real-time inspection in even the most demanding environments. The iNocturn Series are able to detect and visualize any signal in UV from 200 to 700 nm. The small form factor and ruggedized housing makes it ideal for mobile applications. The i2Nocturn Series features a double MCP and up to a typical maximum photon gain of 1,000,000, providing maximum sensitivity.
