Notes: (a) The BeamTrack features are supported by Centauri, StarBright, StarLite, Nova II and Vega meters, Juno, Juno+ and EA-1 interfaces and StarLab application.
Notes: (b) Depending on room airflow and temperature variations.
Notes: (c) For position within inner 30% of aperture. Position measuring center corresponds to geometrical center within <1mm. Position center can be software reset to geometric center or other desired position with Centauri, StarBright or StarLab.
Notes: (d) Assumes laser beam with circular Gaussian (TEM00) distribution. For other modes, size measurement is relative.
Notes: (e) Accuracy spec will be maintained for beams ≥1.8 mm not deviating from center by more than 15% of beam diameter.
Notes: (f) For P type and shorter wavelengths derate maximum energy density as follows:
Wavelength Derate to value
1064nm not derated
532nm not derated
355nm 40% of stated value
266nm 10% of stated value
193nm 10% of stated value
Notes: (g) The 3A-QUAD has a relatively large spectral variation in absorption and has a calibrated spectral curve at all wavelengths in its spectral range to the above specified accuracy. Nova, Orion and LaserStar meters do not support this feature and when used with those meters, the accuracy will be ±3% as above for 532nm, 905nm, 1064nm and 10.6µm but there will be an additional error of up to 3% at other wavelengths in the spectral range 190 – 3000nm.
