Hello,

Do you know how we can increase the exposure time on the DLP NIRscan. In Tiva version 2.1.0 maximum exposure time is 60.960 ms. Should we update the DLPC150 Firmware?

Hi Christian,

Yes, This is the max exposure time of 60,sec per scan. If needed you can increase the number of scans to expose the sample for longer duration.
Could you please let us know your application and why you need longer exposure time?

Regards,

Akhil

Hi Akhil,

Thank you for your message.

We use a long fiber optic between the sample to measure and the DLP. Because of the optical fiber the DLP does not receive enough light. Increasing the number of scans to 10 improves the results but the signal-to-noise ratio is still not good enough. Our idea is to dramatically increase the exposure time and to take only 1 measurement. We tried to change the exposure time in libdlpspec.dll but we can't compile it. I am going to post a new question on the forum about this new problem.

Regards,

Christian
