Dear all,

Not strictly a confocal question but we're looking to stabilize or at 
least monitor the light output from our arc lamp in order to make 
intensity measurements over time. We've found that OptiQuip has such a 
device. Does anyone have good/bad experience with this device that 
they're willing to share (off-list is fine).

Are there any alternatives that I don't know of? One idea I had is a 
monitoring diode that allows you to correct the intensity measurements 
after the fact. (Similar to the monitoring diode the Zeiss LSM510 has as 
an option.) Does anyone make such a device?

Indeed, one alternative is measuring a control sample (e.g. check beads) 
at frequent intervals but we found it requires a skilled operator to 
make such measurements correctly. We're a bit short on those.

Thanks,
- Damir
