The Newport 8-CH Butterfly Fixture (Model 708) is a precision mounting platform designed to house and align up to eight 14-pin butterfly-packaged laser diodes in research, development, and production environments. This drawer-style module provides secure positioning, integrated photodiode monitoring, and dual thermal management pathways via internal TECs and optional water cooling, making it suitable for applications demanding stable optical component integration and accurate temperature control.
Technical Specifications
• Laser Diode Capacity: 8 × 14-pin butterfly packages
• Electrical Interface: 28-pin zero-insertion-force (ZIF) jumper block socket with flexible pin-out configuration per diode
• Photodiode Detectors: Integrated monitoring photodiodes (Hamamatsu S1336-8BK Si)
• Fiber Alignment: Bare fiber holders for pigtail fiber positioning to photodiodes
• Thermal Management: Internal thermoelectric coolers (TECs) with water-jacketed back plane ports for external circulation system integration
• Form Factor: Drawer-style module; optional rackmount kit available
– Key Features
• 28-pin ZIF jumper block supports standard butterfly package pinouts: TEC Anode, Thermistor±, Monitor PD Anode/Cathode, LD Anode/Cathode, Case Ground, TEC Cathode, and No Connect positions
• Integrated photodiode monitoring for real-time laser output verification
• Dual cooling architecture: active TEC control plus external water circulation option for enhanced thermal stability or cost-effective operation
• Bare fiber holders enable precise optical alignment without additional external fixtures
• Compatible with Newport burn-in accessories and laser diode drawer ecosystems
– Typical Applications
• Multi-channel laser diode characterization and burn-in testing
• Integrated photonic system assembly and validation
• Temperature-controlled optical component development
• High-density diode array testing in production environments
– Compatibility & Integration
Designed exclusively for 14-pin butterfly-packaged laser diodes with support for standard pin configurations. Jumper block or custom PCB connectivity allows system integration into larger test platforms. Water cooling ports (back plane) accept standard circulation lines for enhanced thermal control. Rackmount configuration available for equipment rack deployment.
