Product Overview
1. Standard VCSEL Bare Die for 940nm High-Power Pulse NIR Illumination
This 940nm 8W VCSEL bare die is designed for high-power pulse near-infrared illumination, active optical detection, industrial sensing, machine vision support, and custom high-power VCSEL module development.
The product is supplied as a standard VCSEL bare die by default. It is suitable for 940nm high-power pulse illumination modules, active NIR optical detection, industrial sensing systems, machine vision auxiliary lighting, and chip-level VCSEL integration projects.
With 9W typical optical output power at IF = 3.5A, this device provides a high-power 940nm VCSEL source for applications requiring strong pulse NIR output, efficient optical power generation, and compact high-power bare die integration.
2. Key Features
This 940nm 8W VCSEL bare die is supplied as a standard high-power pulse VCSEL device for NIR illumination, sensing, and active optical detection applications.
Key features include 940nm typical wavelength, 8W-class optical output power, 560-emitter VCSEL layout, 10±1μm emitting aperture, 4.9V typical forward voltage, 53% typical power conversion efficiency, 28° typical beam divergence at 1/e², and doughnut-shaped symmetrical far-field output.
The 910μm × 770μm die size, high-efficiency multi-emitter layout, and high-power pulse output capability allow flexible integration into ceramic submounts, chip-on-board assemblies, high-power optical modules, and customer-specific VCSEL packages.
Package-level assembly, wire bonding, ceramic submount mounting, pulse drive condition review, thermal path design, beam shaping, divergence control, and customer-specific optical spot requirements can also be reviewed according to the customer's optical, electrical, thermal, and mechanical layout.
3. Application Development Direction
This device supports 940nm high-power pulse NIR illumination, active optical detection, industrial sensing, machine vision support, high-power VCSEL module development, and custom optical source integration.
In a high-power pulse illumination or active sensing module design, the VCSEL wavelength, output power, pulse width, duty cycle, drive current, forward voltage, package structure, thermal path, beam profile, detector response, optical path, and final system signal behavior should be reviewed together.
The 8W-class output power provides a strong high-power VCSEL option for 940nm optical source designs, especially where strong pulse optical output, efficient power conversion, thermal design review, beam shaping, or customized VCSEL package development is required.
4. Evaluation Sample Kit and Documentation Support
Paid evaluation sample kits can be arranged for selected standard VCSEL chip products, subject to product availability and project review. International express shipping can also be arranged depending on the destination.
An Initial Product Report has been filed with the U.S. FDA CDRH for the Laser Diode Series, including the VCSEL Laser Diode Chip Series. CE-related documentation is also available for project evaluation, including EMC documentation and EN 60825 laser safety / LVD test documentation. Material compliance documentation, including RoHS, REACH, and HF documentation, can also be provided upon request.
For 940nm high-power pulse illumination, active optical detection, machine vision support, industrial sensing, and high-power VCSEL source projects, bare die mounting, ceramic submount assembly, chip-on-board integration, wire bonding, beam shaping, pulse drive review, thermal design, or customized package discussion is available according to the project requirements.
