Description

The fully automated DWL 66+ laser writing system is located inside an environment chamber for stable environment of the system with controlled laminar airflow and temperature stability. The chamber is situated on a granite base with air cushions for vibration isolation. The optical system includes highly reflective mirrors and acousto-optic modulators for real-time beam correction. The laser is 405nm wavelength (h-line).

Lens & Resolution

  • 2 mm lens (optical autofocus): 600 nm
  • 10 mm lens (pneumatic autofocus): 2 µm
  • 40 mm lens (pneumatic autofocus): 10 µm
