Silicon Wafer Inspection With SWIR Cameras
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. During the manufacturing process, foreign particles and defects may appear on the top, bottom, inside or in between the wafers. It is important to find the location of these defects. Defects do not initially affect the chips functionality, but they do end up...  Continue Reading..

Technical Note: Auto Gain Control And Non Uniformity Correction
In SWIR cameras, the InGaAs FPA sensor can be difficult to manufacture so that all pixels are fully functional. As a solution, Raptor Photonics cameras use Non-Uniformity Corrections (NUC), or gain and dark current corrections, in order to obtain the same quality as a single A/D device. In addition, Raptor’s family of SWIR cameras is also capable of continuously performing Auto Gain Control (AGC) on the onboard FPGA. This application note...  Continue Reading..

SWIR Multiplexing: Temporal Multiplexing For Cost-Effective Multispectral Solutions
Short-Wave Infrared Temporal Multiplexing For Cost-Effective Multispectral Solutions
Temporal multiplexing is an alternative approach to hyperspectral imaging that uses a fast LED technology. Instead of broadband illuminating and diffracting the spectrum of light in the camera, a broadband sensitive chip is used, and the illumination spectrum is varied over time via fast triggering.  Continue Reading..

PRODUCTS

The Owl 640 Series from Raptor Photonics comprises a number of VIS-SWIR cameras with high resolutions and low noise readouts. They are ideal for a variety of applications, including surveillance, astronomy, beam profiling, hyperspectral imaging, solar cell inspection, and other scientific applications.

The Ninox 1280 offers visible extension from 0.4 µm to 1.7 µm to enable high sensitivity scientific imaging using a 1280 x 1024 InGaAs sensor. With cooling to -15 °C, the camera achieves typical dark current readings of <2,000e/p/s at this temperature, allowing for longer exposure times. The 10 µm x 10 µm pixel pitch enables the highest resolution imaging. The camera will offer ultra-high intra-scene dynamic range of 69 dB enabling simultaneous capture of bright and dark portions of a scene.

The Owl 1280 from Raptor Photonics offers visible extension from 0.4 µm to 1.7 µm to enable high sensitivity imaging using a 1280 x 1024 InGaAs sensor from SCD. The 10 µm x 10 µm pixel pitch enables the highest resolution imaging. It will offer less than 50 electrons readout noise (rms) and with a high intra-scene dynamic range of 69 dB, this enables simultaneous capture of bright and dark portions of a scene.

Allied Vision’s Goldeye cameras are short-wave infrared cameras (SWIR) featuring InGaAs sensor technology making them sensitive in the SWIR spectrum ranging from 900 nm to 1,700 nm. These cameras are available in the Goldeye G/CL-033 is a TECless InGaAs model and the Goldeye G/CL-008 Cool TEC1.

FLIR’S A6260sc is a short-wave infrared (SWIR) camera with high-speed performance and fully customizable features that sets the standard for SWIR cameras for science and R&D applications. 

The New Imaging Technologies' (NIT) wide dynamic range (WDR), InGaAs shortwave infrared (SWIR) sensors and camera systems are designed with the purpose of delivering a dynamic range greater than 140 dB in a single snapshot without any processing or tone mapping. 

The new LineCAM12 from Princeton Infrared Technologies is an InGaAs linescan camera designed to operate in the shortwave infrared (SWIR) and visible spectrum, from 0.4 to 1.7 µm. This camera utilizes a 1024 x 1 state of the art InGaAs linear array imager on 12.5μm pitch. It is currently available in a 250 mm tall pixel model for spectroscopy, and 12.5 mm square pixel model for machine vision applications.

Princeton Infrared Technologies offers the 1280SCICAM lattice-matched InGaAs camera designed for excellent SWIR and visible imaging 1280 x 1024 resolution at high frame rates greater than 95 fps at full frame size. The small pitch array at 12 μm, combined with the high quantum efficiency of the lattice-matched InGaAs arrays enables excellent imaging in the SWIR and visible band.

  • SWIR For Hot-End Glass Bottle Defect Inspection And Imaging

    Manufacturers of glass hollowware have long sought a way to pick out defective product at the hot end of their process, while the pieces are still above 200ºC. At that glass inspection stage, rejects are identified, then shunted aside and reprocessed efficiently, greatly reducing scrap.
