VT2030 Vertical Laser Film Removal Machine
Non-contact laser ablation of coating layers on large-format coated glass
Maximum working size 2000 × 3000 × 30 mm

Film-removal speed 0 – 12 m/min
Any pattern geometry — easily optimized for different coated glass types, window sizes, and geometries
The VT2030 is a machine for removing coating layers from large-format coated glass. The removal process is laser ablation: a high-pulse fiber laser ablates the coating material. Because glass is transparent to the near-infrared wavelength of the pulsed fiber laser, the glass substrate absorbs very little heat and is not damaged. Uniformly tempered glass can have its coating removed reliably using MOKE Laser's process.
In addition to the extremely fast fiber laser, the VT2030 uses a high-speed scanning galvanometer module that delivers laser pulses onto the glass substrate at a film-removal speed of 0–12 m/min. The state-of-the-art oscillating galvanometer sweeps across patterns of different widths and shapes, with laser-to-galvanometer synchronization at the microsecond level — delivering pulse energy with great precision to optimize finish quality at the highest possible processing efficiency.
To handle large-format glass, the VT2030 uses a moving-gantry structure. The CNC system controls the motion of the oscillating galvanometer, covering a large working area: the gantry carries the galvanometer along the areas where coating must be removed, ensuring accurate tracking of very long or complex contours, while the galvanometer executes the fine details of the ablation process at extremely high speed.
The VT2030 supports the glass on felt wheels. Glass can be loaded and unloaded manually or by robot arm, cantilever crane, or similar handling equipment.

Design Details
Frame
The machine uses a locally welded structure with modular assembly.
Beam
An independent aluminum-profile motion crossbeam.
Axes
Four CNC servo motion axes. The laser scan head is mounted on a ball-screw-driven Z axis perpendicular to the glass; the X, Y1, and Y2 axes are all driven by rack-and-pinion mechanisms.
Z Axis
The galvanometer module is driven by a powerful low-inertia servo motor on a rigid ball-screw module. Via CNC commands and sensors, the Z axis keeps the laser beam focused on the glass surface at all times, regardless of thickness.
Fume Extraction
A dedicated airflow system: a blow-across circuit pushes smoke and dust away from the removal zone with a high-speed airstream, and an extraction circuit removes it onto a filter.
Laser Source
A fiber-delivered nanosecond MOPA laser generator integrated onto the machine's X-axis frame to preserve pulse shape and quality. Pulse shape and duration are selected automatically for optimal film removal on the most common coating types and thicknesses.
Scanner
A high-precision digital oscillating galvanometer in a waterproof, dustproof enclosure. The long-focal-length objective lens allows mounting at a distance from the glass, with a protective window shielding it from ablation debris. Controlled in real time by the CNC system at up to 25 m/s spot speed.
Non-Contact Laser Ablation
Maintenance-free, extremely flexible and fast compared with traditional coating-removal processes — any pattern geometry can be processed.
No Substrate Damage
Glass is transparent to the near-infrared laser wavelength, so the substrate absorbs very little heat and is not damaged.
High-Speed Galvanometer
Moves the laser spot across the glass at up to 25 m/s with microsecond-level laser synchronization and precise spot positioning.
Moving-Gantry Structure
Covers large working areas and accurately tracks very long or complex contours while the galvanometer executes the fine details.
Integrated Fume Extraction
The scanning module integrates a fume-extraction system that effectively collects all smoke and dust generated during coating removal.
No Water Cooling Required
The nanosecond MOPA fiber laser offers high efficiency, excellent beam quality, high stability, and long service life — with no water cooling.
