khs-instruments provides a wide range of standard and OEM optoelectronic products.
Our standard products include line scan cameras, MPPC modules and 2D position detectors. If you cannot find a product that meets your requirements, please contact us. Many of our products are developed for customer-specific applications.
Unlike 2D cameras, line scan cameras use a single line of photosensitive elements (pixels). This allows a large number of pixels and, in many cases, larger pixel areas than comparable 2D image sensors.
Since only a single line has to be read out, high line rates can be achieved. Larger pixels can collect more electrons, which can provide higher sensitivity and lower noise, particularly in low-light applications.
Our line scan cameras are available with different sensor technologies, including CCD (Charge-Coupled Device), NMOS (N-type Metal-Oxide-Semiconductor), CMOS (Complementary Metal-Oxide-Semiconductor) and InGaAs sensors.
InGaAs cameras are suitable for the near-infrared spectral range from approximately 800 nm to 1500 nm and beyond.
Standard CCD line scan cameras provide a cost-effective combination of readout speed and sensitivity.
For low-light applications, cameras with back-thinned CCD sensors are also available. The back-thinned sensor structure provides higher sensitivity than conventional front-illuminated CCD sensors and can achieve approximately twice the sensitivity, depending on wavelength and sensor type.
To reduce dark current, back-thinned CCD sensors are often cooled. Line scan cameras using the Hamamatsu S7031 and similar sensors are available. Please contact us for further information.
