Date Announced: 26 Apr 2023
Brand new from ANDANTA are InGaAs linear sensors with 1024 x 1 or 512 x 1 pixels with different square and rectangular pixel sizes and dimensions. These sensors are now also available with an uncooled ceramic package.
The linear sensors consist of a linear InGaAs photodiode array, which is connected to integrated p-on-n readout circuits.
They are sensitive in the standard InGaAs spectral range of 0.9 – 1.7 µm. The pixel operability is > 99% and the quantum efficiency > 70% at 1550 nm. 16 different gain settings are possible.
With its 1 to 2 outputs, the linear sensors achieve a readout rate of approx. 40 kHz (to be specified) at a pixel rate of 22 MHz (data rate 11 MHz).
For the linear sensors with 512 x 1 pixels there are pixel dimensions available from 25 x 25 µm square, 25 x 250 µm rectangular (half height) and 25 x 500 µm rectangular (full height). For the linear sensors with 1024 x 1 pixels there are existing pixel dimensions from 12,5 x 12,5 µm square and 12,5 x 250 µm rectangular.
All linear sensors come in a 28-pin ceramic DIP (CDIP) package without any thermoelectric cooler. They can be operated at room or ambient temperature.
The sensors support SPI protocol for command register setting. The sensor amplification, a control of the sensor power consumption and the pixel-by-pixel order of the output signal can also be adjusted.
Key applications include NIR spectroscopy, web inspection, optical coherence tomography (OCT), NIR scanners, semiconductor inspection and process monitoring.
