Help me in choosing optical chopper

[udayag]

hi friends
I am going to buy optical chopper system for my work. But i need some clarification about system. If i want to chop say 2mm diameter of the beam, say it has of chopping frequency from 500Hz to 1000Hz. What is the difference if i chop at 500Hz and 900 Hz except the frequency.

Thank you for advance wishes

Note the bold in your question that I added for emphasis. The chopping frequency is variable and can be set to any value in the range given. It's up to you depending on your application.
