During process observation within VIS spectrum, chromatical aberrations occur caused by the difference in laser and observation wavelength.
The thermal focus shift is typically a problem caused by optical glass lenses.
We have extended our existing series of telecentric F-Theta lenses with a focal length of 48 mm to meet the ever increasing laser pulse power in micro processing.
Sill Optics presents the new zoom beam expander S6EXZ0940/574 which is suitable for high power UV lasers at 355 nm.
