First of all, Happy New Year to everyone ! Good Health and good mood !
Please find attached a very simple blanking method we have proposed to a company doing copper vapor lasers (looooong time ago ! Anyone remember Spectronica ?)
The beam first hits the scanner mirror next to the shaft, then goes to the adjustable ''return'' mirror. We only have to adjust this mirror so the reflected beam hits the scanner mirror at the other edge. Then the beam goes back to the ''return'' mirror and leaves the setup with the same orientation it entered it.
In this setup, there is no need to re-glue the scanner mirror vertically, so the speed is not affected. By placing the ''return'' mirror approx 10cm away, you get a fast blank that can easily follow X and Y and needs only a small signal to blank the beam (around 1 volt)
This is not a '100% perfect' blanking method as it slightly swifts the beam (very little though), but it has worked nicely in most applications, even graphics.
A benefit is that the scanner mirror is hit at near zero degrees, so a 8mm wide mirror (for example) will accept an 8mm beam.
(Optionally, the adjustable mirror for returning the beam to the scanner can be placed directly under the scanner, on the baseplate facing up. By doing this, the exit beam goes backwards towards the source).
Enjoy responsibly !
All the best to all !
