Sensor differences between the Mk1 and Mk2
Rayfin Mk1 (a) vs. Mk2 (b)
Rayfin Mk1
Pixel count: 21 million pixels
Pixel size: 1.12 µm (L and W)
Pixel surface area: 1.2544 µm2
Rayfin Mk2
Pixel count: 12.3 million pixels
Pixel size: 1.55 µm (L and W)
Pixel surface area: 2.4025 µm2
The Mk2 has a larger sensor
Each pixel has double the photon-catching area per pixel compared to the Mk1
It is also a newer generation sensor
The Mk2 will need less than half the light of the Mk1 to achieve a similar result.
