- 9x11-inch-large digital sensor. The company tends to refer to it as 8x10 as that is the closest format that people search for.
- 75 micron pixel size
- 12MP resolution
- Live view for easy focusing
- Video modes (all progressive):
- Up to 26fps: Full sensor scan 3888 x 3072 and optional crop sizes: 3840 × 2160, 3840 x 1600, 1920 x 1080.
- Up to 70fps with pixel 2x2 pixel binning: Full frame: 1944 x 1536 - 14 bit ADC
- The US price is $106,000, available now
The LS911 sensor uses a rolling shutter. Rolling shutters can produce distortions, but the LS911 is said to handle it well, as shown in the test video:
Is this butted or stitched?
ReplyDeleteWhat litography and pixel design does it use?
The text mentions a device of 9 inch x 11 inch. This results in a diagonal of 14.21 inch or almost 360 mm. This does not fit on the largest wafer available in today's industry. So I guess that the device is butted. Even teh 8 inch x 10 inch will not fit on a 300 mm wafer.
DeleteHow big are their reticles, full wafer or is it like 25x25mm or something and thus they need a crapload of "sensor" tapeouts?
ReplyDeleteThe reticle size depends on the litho tools used in the fab. Which do they use ? I do not know .....
DeleteIt is easy to find the background of the founder, Bill Charbonnet, on LinkedIn. The company seems to have been in business for 4 years. Prior to founding the company he was an account manager with various duties including "Helping customers with orders, and custom cable inquiries." It is good to dream big and I wish him good luck. At $106,000 per camera, I guess you only need to sell a few to stay afloat. Can't explain the claim of 9x11 format using 300mm wafers. Even 8x10 has a diagonal of 12.8 inches so maybe it is like image sensor diagonals, where a 1/4" sensor has a diagonal less than 1/4".
ReplyDeleteYes, it does not fit onto 12-inch wafer. Half of the sensor fits, though. Or a quarter fits onto 8-inch wafer.
DeleteThis might explain why there is no color version - it's difficult to make a seamless butting of an RGB pixel array.
What is the market for these cameras?
ReplyDeleteButted and stitched monolithic CMOS devices are used in medical X-ray applications (ask my former colleagues at Teledyne DALSA in Eindhoven). Based on the large pixel size I do suspect that this is for medical as well. Who else is using 75 um pixel pitch ???
DeleteThank you for the answer. That was my guess as well but was baffled that the company doesn't mention it front and center.
