Typically, NIR sensitivity is enhanced by increasing the thickness of the sensor’s epitaxial layer. However, this impacts MTF and limits the effective resolution of the sensor. The new Red Fox process modifies the
sensor’s sensitive layer to achieve an optimal balance between NIR sensitivity and MTF.
The GMAX0505RF achieves a QE of almost 34% at 850 nm and 14% at 940 nm. In comparison, based on publicly available EMVA test data some competitive image sensors only offer a QE of 20% at 850 nm. This equates to a 70% improvement in QE performance.
As the Red Fox process can be applied to any GMAX products, Gpixel’s anticipates other GMAX RF products will be released in the near future. Engineering samples of the GMAX0505RF are available now for evaluation.
what IS the mtf?
ReplyDeleteMTF stands for modulation transfer function
DeleteThere are a few "optics basics" articles on the website of edmund optics - for example for MTF: https://www.edmundoptics.com/knowledge-center/application-notes/imaging/modulation-transfer-function-mtf-and-mtf-curves/
DeleteIs there any technical (non-marketing) information provided?
ReplyDeleteSmells like pyramid structure technology to trap NIR light to increase QE.
ReplyDeleteGood detector, we are now completing the development of the camera.
ReplyDeleteIt is not easy to pick up a lens for such a small pixel 2.5 um.
