Tucsen High QE Libra CMOS Announced

High QE, small pixel size

Recently Tucsen had a presentation on their new Libra CMOS cameras which includes some nice improvements in sensor performance.

Key highlights were:

• Improved QE at 92%
• Large Full Well Capacity (48,000 e)
• Native binning / debin system

In a recent presentation here a series of improvements were listed, among them a smaller pixel size selection option which supports a drop in pixel size to ~ 3.27um. From the explanation I assume the camera runs natively in a binned mode to produce 7.x um pixels, but can be optionally de-binned.

Each of the cameras (3 models announced) appear to have this feature, as shown below.

I’m more interested in the full well, as having a ~50k e full well seems a nice improvement in dynamic range over current options. Once item that was very interesting to me is that the full well capacity does NOT reduce when enabling the higher resolution mode. If this is correct, a 3.x um pixel with a 48ke full well would still be quite a nice bump in range and quite a feat!

For pricing, the presentation noted 0.4x the cost of a “classic CMOS”. I’m curious what that means in an actual dollar amount.
