It might be beacuse their microscopy requirement might be using a camera of some sort which would cause strobing at lower fequencies.
For helio; I would consider using a lower PWM with a lot of capacitor filtering to give constant light at the LED, or even a linear current source. That would give zero strobing.
Unless you require the LEDs to actually flash? I know some LEDs can give higher brightness at certain freq/duty but isn't that a factor caused by the human eye, which would not affect a camera?

IMO a camera objective is conceived to react as the human eye
