Hi All,
Recently, I worked on a homemade drum plotter to expose negative acting film. I added some photos under Photo Albums > Drum_Plotter_V_Sahin and there is also a video on youtube
(http://www.youtube.com/user/vulcanmicronics).
Later, I will add more videos.
Short performance summary of the plotter
Resolution 832x2032 dpi
Optimum exposure time on RLN-4 Film=9.5 microseconds with 405nm 150mW laser.
Optimum drum speed:~615 rpm
Thanks,
Volkan
