FAQ about sCMOS scientific cameras

FAQ for Large sensor / pixel camera - MX377 model

1. What gain modes would be available?

Standard ones are 10 and 12, planned is the 14 bit mode with CMS (16bit).

2. What frame rate can be reached in what gain mode?

For 10bit it would be around 60 fps in full resolution.
For 12bit around 45 Fps.
If 14-bit is available it should reach 10+fps

3. What will be the expected full well capacity (FWC) in gain modes?

For 10 and 12 it should be around 120 000 e-.
For 14 bit the expected value is 100k e-.

4. How can the camera reach such speed with such resolution?

This model is equipped with PCIe interface (X4 Gen3) allowing the bandwidth of 32 Gb/s

5. What is the expected temperature when using TE Cooling?

With the built in Thermoelectric Peltier cooling the temperature could be around -10C

6. What is the expected readout noise?

For the 10 and 12bit modes it is 4e-.
For 14 bit mode with CMS (16bit) measurements are coming soon

7. Will Global Reset be available?

The sensor uses Rolling shutter technology to increase sensitivity and S/N ratio. For Global shutter sCMOS sensors please check HERE

8. Will the camera provide time stamping?

There is a timestamp feature in the camera - resolution 4us.

9. Will the camera have a window in front of the chip?

Absolutely, cooling requires this.
If the "sensor glass" is meant - the sensor will be available in the "Taped Glass" version so it will be removable if necessary.

10. What about Binning and Windowing, ROI?

The sensor does not support Binning, but it is implemented on the camera side - Binning 4x4
Windowing or ROI (Region of interest) is supported and integrated.

11. Does the chip have tip/tilt adjustments to align to the optical axis?


12. What versions of the Gpixel sensor will be used and offered?

XIMEA is planning to offer the GSENSE6060 sensors with regards to the sensor grade provided by Gpixel.
There will be three grades 0, 1 and 2 (or E for “engineering sample”) which differ in the amount of defects allowed.
Typically grade 0 will be omitted as the chances of producing such a sensor are low which results in highly uncertain lead times.
Also, there are front-side and back-side illuminated options available.

FAQ for Cooled cameras with sCMOS including BSI

1. Can the mount part of the camera be removed?

Yes, there are two options of mounts for this cameras (M42 and C-mount) and both can be removed, allowing closer access to the sensor.
Please be careful when attempting this operation because there is a rubber ring around the mount which can potentially help fine tune the lens connection and this part is easily damaged or lost.

2. Can the fan part of the Cooling be removed?

Yes, but besides voiding the warranty, this will automatically turn off the cooling completely including the temperature sensor in the camera so even the Peltier will stop working.
Thus, the picture quality can get considerably reduced.

3. What materials are used in the diversely looking camera housing?

The material of the camera window is stainless steel 303 (1.4305), which helps with the sealing.
The middle part is made of copper alloy that improves the cooling effect and the fan is from aluminum alloy.

4. How is the camera powered?

The power is provided to the camera through USB Type-C cable, but to power the Cooling system all parts of the setup (camera, cable, computer and other potential accessories) should support a so called USB PD (Power Delivery) specification.

5. How is the ADC for bit readout set up in these cameras?

You can read more about CMS, HDR and STD modes HERE

6. What are the differences between CMOS and sCMOS ?

You can read more about CMOS, CCD or sCMOS (including backside illumination): HERE

7. What is the glass window material and thickness?

The window material is Sapphire glass with Ar/Ar@VIS coating.
Dimensions of the glass are:
  • Diameter 35mm
  • Thickness 1mm +/-0.5mm

8. What is the sensor glass material and thickness?

It is 1mm thick D263T glass without AR coating.
