The new LED light source with 80W up to 120Hz and 1μs flash period
The Blue-X-Focus is a powerful LED light source, especially designed by isi-sys for digital image correlation:
The short, single wave length (blue) improves the optical transfer function properties especially a) at the image boarders for conventional lenses and b) for high resolution, small FOV set-ups such as the Micro 3D stereo sensor.
The pulse mode reduces motion blur and maximizes light power at lowest possible heating of the object surface
Large beam expansion range from 3,2° to 60° for small to large field of view. Operation through small windows
A polarization-filter (optional) is suppressing direct reflections in combination with a second pair for the sensors
The short wavelength can be used in combination with bandpass filters for measuring on hot samples
Power: Standard operation with 80W in continuous mode or 120W for pulse mode depending on duty cycle. Example for 0,7 duty cycle: 105W @ 240Hz and 2,9ms flash period. Power adjustable manually or external by pulse length and frequency as well as automatically limited depending on temperature.
The focusing adapter for standard DIC is from 5° to 60° expansion. The version for small FOV is adjustable from 3,2° to 4,7° expansion corresponding to e. g. 5mm x 3mm at 53mm WD or 300mm x 140mm at 1800mm WD (working distance)
Mounting is possible horizontal or vertical via M6 or ¼” threads
The cooling air stream is directed from the front inlet to the backside to avoid hot air waves in the images.Power: Standard operation with 80W in continuous mode or 120W for pulse mode depending on duty cycle. Example for 0,7 duty cycle: 105W @ 240Hz and 2,9ms flash period.
Application example for DIC on small FOV (magnification 1:1 approx. 14x10mm @ 12Mpx, Rodagon 135mm)
