Note:
(1) For laser wavelength 1030-1090 nm.
(2) All angles are in mechanical degrees.
(3) With F-Theta objective f = 160 mm. Speed value varies correspondingly with different focal lengths.
(4) Reapeatibility and temperature drift are measured within this speed.
(5) Single-stroke font with 1 mm height.
(6) Long-term temperature drift is given under an ambient temperature environment of 25°C. and a working load under 500W. Temperature drift testing with high laser power is strictly prohibited. High laser power could induce thermal deformations in both the optical and mechanical systems, making it impossible to differentiate whether the drift is originating from galvanometer scanner itself or due to deformations in the optical and mechanical systems.
(7) Appropriate delay parameters must be configured for normal operation of the galvo scanner. Failure to do so may result in abnormal operation of the galvo motor and even irreversible damage to the motor! Please contact PSI engineers regarding relevant parameter configuration issues.
(8) Wavelength customization available. Please consult PSI engineers!
