Overview: The Lightning II Digital Scanning Platform by Cambridge Technology is an advanced system designed for ultra-high accuracy and speed in laser material processing applications. It integrates state-of-the-art technologies in laser/scanner control, communications, servos, drives, galvos, encoders, and mirrors.

Key Components:

• LII Scan Control System: Provides synchronous modulated laser control.
• GSBus™: A 24-bit, 8-channel, high-bandwidth bi-directional communication system.
• LII State Space Servo: Anticipates laser position faster than feedback.
• LII PWM Drive: Generates power efficiently with a 90% efficient amplifier.
• LII Encoder Galvos: Utilizes custom MicroE 24-bit encoder technology for high accuracy.
• Beryllium Mirrors: Designed for high speed and fast settling performance.

System Features:

• Includes high-performance MPM-20D galvanometers, shaped Beryllium mirrors, and a precision-engineered resonant structure motor block.
• Utilizes Lightning II State Space digital servo drivers with PWM amplifiers and GSBus communications.
• Offers an optional XY2-100 to GSBus adapter interface for traditional controller compatibility.
• Features the LII Distributed Control System for enhanced vector and laser control via USB communications.
• Comes with setup and diagnostic toolset, interconnecting cables, and cooling hoses.
• Provides precision alignment, balancing, and digital servo tuning to customer requirements.

Control Schemes:

• Traditional Control Scheme: Relies on position feedback with required delays for mirror positioning and laser synchronization.
• Lightning II Control Scheme: Eliminates delays by dynamically calculating synchronization and optimizing motion based on maximum acceleration.

ScanPack Features:

• Maintains constant energy density by modulating laser parameters with scanner speed and acceleration.
• Ensures speed and accuracy around sharp corners by linking vectors based on acceleration limits and user-defined constraints.

Specifications:

• Galvo Motor Models: MPM-14D/20D/30D with various beam aperture sizes.
• Power Requirements: +15 to +48 VDC, 3 Amps continuous, 6 Amps peak.
• Operating Temperature: 15º to 35º C.
• Digital Communication: GSB/USB/XY2-100.

Setup Tools: Includes a function generator and virtual oscilloscope for probing scanner and servo parameters over a USB interface.

Product Range: Available in various sizes and configurations, with mirror coatings for different laser wavelengths. One-, two-, and three-axis systems are available.
