Abstract

The new 512x512 pixel large SAPHIRA infrared eAPD array is an extension of the earlier 320x256 pixel small SAPHIRA device, using the same 24 micron pixel design mated to a larger format readout integrated circuit. It was developed by Leonardo, in partnership with MPE, NRC and ESO. The first packaged test devices were completed in 2021. The bare ME1120 ROIC has been tested in the 64-channel mode at MPE with the ESO NGC controller. The possibilities and adaptations of e-APD technology to provide noiseless large format science grade arrays for long integration times are also discussed.
