ANDANTA NEWS: InGaAs-linear sensors LDA1024 + LDA512 - now uncooled

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.

The data sheets of the new InGaAs linear sensors 1024 x 1 and 512 x 1 can be found on the ANDANTA website at:
