1
Distance between edge of head and working surface. This distance will vary with laser divergence and lens
tolerance.
2
Maximum temperature induced gain drift is 0.01 %/C; maximum offset drift is 25µR /C°. Drift is specified per axis.
3
Writing speed ratings are at +/-24VDC, 3.5 Amps Power Inputs with 10mm chamfered silicon mirrors. Higher
speeds can be expected with 7mm mirrors. Slower speeds with glass mirrors.
