Using a microscope objective to image a scintillator?

Mark, Matt,

This is used for low light imaging. Specifically, near-field HEDM images. Typical exposure ~ 10 seconds.

Hi John,

Can you describe the application for the camera?  What are the typical exposure times?  Is it being used for imaging or spectroscopy?  For spectroscopy the Princeton Instruments cameras with ADLightField can control not only the camera, but also the spectrometer slits and grating.

Hi John,

The areaDetector website has a list of cameras, some of which are cooled. I haven’t used QImaging cameras, but I can recommend Andor CCDs (USB2 based). On one of our beamlines we have had an Andor iKon CCD being used as the main detector for about 8 years. The latest versions of those cameras can be cooled down to -100C. These are not high frame rate cameras, and are optimized for low noise and astronomy (low light, long exposure) applications.

A more affordable option might be a camera from SBIG, which have several cooled options.

If you’re more interested in frame rates, a sCMOS camera might be best. These will have the higher speed readout options like USB3.

Cheers,

Matt

Happy New Year!

We have an old QImaging RETIGA 4000DC camera. This is a Peltier cooled (down to -45 C) sensor with Firewire interface, ~ 4 Megapixel.

I am looking for a replacement.  There is a RETIGA LUMO which is similar but with a USB3 interface?  Does anyone know if the existing ADQimaging works with this camera/interface?

Does anyone want to recommend another cooled camera with existing EPICS support?

Thanks,
