Re: Recent Digital SHG

Thank you all.
I'm going to change to Richardson grating from very old Diffraction Products Inc(20 years old).
It takes 3weeks.

Therefore I block it using red filter (R64) in the lower part of the binoviewer. When I use other wavelengt...

Re: ROT2 command of IRIS

Thanks Wah.
I'm beginner in SHG. So I must learn more about dogital procedure.
ROi is helpful for me.
I tried Vdub and SLim recently.
I Try to more experience about DigitalSpectroheliograph.

Thank you.

Re: ROT2 command of IRIS

Maybe,for visual using oscillations is 20-30 per second vibration and for graphical using is 5-10 per second.
For photo it need not make vibrate so fast. Conposite procedure is useful for smoothing.

Re: ROT2 command of IRIS

The binocular device is used to facilitate optical axis adjustment.
In order to use it as a spectrohelioscope, a littrow type optical system is not appropriate.
Off-axis light causes distortion.
