How to get MATLAB to recognize my Thorlabs Scientific Camera Link Camera?

I have a Thorlabs Scientific Camera (Camera Link) that I am trying to use with the Image Acquisition Tool. My camera isn't appearing under the Hardware Browser automatically like its supposed to. Does anyone know how to fix this? Thanks!

Hi Kat,

Unfortunately the Image Acquisition Toolbox is no longer supported by Thorlabs cameras. It’s been replaced with a new .NET interface in versions 3.0.0 and up. With this interface you can control the camera by calling Thorlabs .NET assemblies in MATLAB script. I recommend checking out the most recent version of the SDK and looking over the Thorlabs Camera MATLAB Interface Guide as well as the MATLAB programming samples.

The SDK software can be found here: https://www.thorlabs.com/software_pages/ViewSoftwarePage.cfm?Code=ThorCam

The ThorCam Software includes both ThorCam and the SDK, but you can navigate to the ‘Programming Interfaces’ tab to get just the SDK.

Hope this helps!

Thank you for the information! It has been very helpful.

If I may ask one more thing, I am now following the Thorlabs Camera MATLAB Interface Guide. The line to make the .NET assembly visible to MATLAB:

NET.addAssembly([pwd, '\Thorlabs.TSI.TLCamera.dll']);

doesn't seem to be working. When I run it, MATLAB displays the busy signal indefinietly. I have made sure the managed_64_lib library and my MATLAB .m script are in the same folder (on my desktop). Am I missing something that is causing the issue? Thanks!

Hi Kat,

I have the same problem when I try to run the script "ThorlabsCameraGUI".

I get the following message:

Message: Could not load file or assembly 'file:///C:\Users\PNP\Desktop\Matlab\Camera\Scientific

Camera Interfaces\MATLAB\Thorlabs.TSI.TLCamera.dll' or one of its dependencies. The system cannot

find the file specified.

Error in ThorlabsCameraGUI (line 42)

Did you solve this problem yet?

Dear Jonathan Friesen,

I have attached thorlab CS505 CU cam with my PC. And using its GUI interface i successfully getting the imgae frames in MATLAB. But I don't where the images are saving. Example

Starting the camera.

Image frame number: 2

Image frame number: 6

Image frame number: 11

Image frame number: 15

Image frame number: 19

Image frame number: 24

Image frame number: 29

Image frame number: 33

Image frame number: 37

Image frame number: 42

Stopping the camera

WHERE, these frames are saving... Any Idea?

Hi,

I am not quite sure if your specific camera is supported, but have you tried to install this support package?

Once installed, use webcamlist to see the cameras available, and webcam command to create a camera object.
