Profile details

Import selected Spot profile

Lens focal length50.8 mm

Measured spot0.12 mm

Rayleigh range1.067 mm

Measured spot is the focused beam diameter imported from the Spot tool. Rayleigh range is calculated from waist radius, CO2 wavelength, and M²; it estimates how quickly the beam grows away from focus.

Measured kerf comes from physical coupon measurements. Strip tests use (designed width - measured width) divided by the number of cut lines; square and hole tests compare CAD size with measured part size.

Calibration diagram

Cut or mark a ladder at several focus depths so the best edge, char, and fit can be chosen from real samples.

Better result checks

Kerf calibration: Cut a calibration coupon with the same power, speed, air assist, focus, and optical profile before saving production offsets.

9-spot alignment test: Mark low-power dots at near, middle, and far positions across X and Y. If dots drift between corners, correct alignment first or enter the measured alignment loss before trusting focus depth.
