Could a IMX585-AAMJ1 work ? #16

The IMX585-AAMJ1 is a monochrome 3840 (H) × 2160 (V); approx. 8.29M pixel; Maximum frame rate in All-pixel scan mode: 12 bit: 60 frame/s, 10 bit: 90 frame/s.

My thinking was that with a monochrome sensor, I would only need to remove the glass window over the sensor (which absorbs UV) and replace with a window made out of UV fused silica or fused quartz. That way I would not have to deal with removing the Bayer filter. Basically to use the 4K sensor with raw data for spectroscopy from ~220 to ~ 1250 nm.

I'm was at the toying with the idea stage, when noticed your project and though that looks nearly perfect. Thanks in advance.

Hell yeah. I've been using monochrome IMX585 with this project for a while now, the driver also supports monochrome with the dtoverlay=imx585,mono flag.

Here is my experiment with UV photography - though I think the lens itself is absorbing UV. _DSC5555

IMX585-AAMJ1= IMX585-AAQJ1 in terms of hardware (and actually software, just that you need to tell ISP that this is a monochrome sensor).

So if you can get the sensor then just drop it in.

For me I'm mostly using it for H-alpha solar imaging _DSC4266

Absolutely perfect, thank you. That is music to my ears. I am moving at the moment, but once moved I know what I'll be doing.

So if you can get the sensor then just drop it in.

A quick search using "IMX585-AAMJ1 site:aliexpress.com", says that I probably can.
