Is there any documentation available for the IR cut filter on the lenses - I see that it cuts at 650nm, but is there any more information than that? I am trying to simulate the global shutter model camera in a high-fidelity virtual environment, and while the sensor datasheet gives the response for the sensor itself the filter doesn’t seem to be documented anywhere. ---

Yeah, we don’t have anything other than it’s for 650nm. We don’t exactly pay a lot for these lenses. If you want documentation head over to edmunds optics and you can buy precision stuff. > **[2mm FL f/5.6 IR-Cut, Blue Series M12 Lens | Edmund Optics](https://www.edmundoptics.com/p/2mm-fl-f56-ir-cut-blue-series-m12-imaging-lens/41683/)** > > TECHSPEC Blue Series M12 Lenses feature megapixel finite conjugate and are designed for small pixel sensors. ✓ Shop now with Edmund Optics! ---

No worries, I suspected as much.
