Product Overview
1. Standard VCSEL Bare Die for 940nm Medium-Power NIR Sensing and Illumination
This 940nm 300mW VCSEL bare die is designed for medium-power near-infrared sensing, pulse illumination, optical detection, machine vision support, industrial sensing, and compact VCSEL source module development.
The product is supplied as a standard VCSEL bare die by default. It is suitable for 940nm pulse sensing modules, compact NIR optical sources, active illumination systems, industrial optical detection, machine vision auxiliary lighting, and chip-level VCSEL integration projects.
With 290mW typical optical output power at IF = 350mA, this device provides a medium-power 940nm VCSEL source for applications requiring stronger optical output than low-power sensing devices while maintaining compact bare die integration.
2. Key Features
This 940nm 300mW VCSEL bare die is supplied as a standard medium-power pulse VCSEL device for NIR sensing and active illumination applications.
Key features include 940nm typical wavelength, 300mW-class optical output power, 48-emitter VCSEL layout, 10±1μm emitting aperture, 2.0V typical forward voltage, 42% typical power conversion efficiency, 20° typical beam divergence at 1/e², and doughnut-shaped symmetrical far-field output.
The compact 330μm × 330μm die size and multi-emitter structure allow flexible integration into ceramic submounts, chip-on-board assemblies, compact optical modules, and customer-specific VCSEL packages.
Package-level assembly, wire bonding, ceramic submount mounting, drive condition review, 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 medium-power NIR sensing, pulse illumination, active optical detection, machine vision support, industrial sensing, and custom VCSEL source integration.
In a medium-power sensing or active illumination module design, the VCSEL wavelength, output power, drive current, duty cycle, forward voltage, package structure, thermal path, beam profile, detector response, optical path, and final system signal behavior should be reviewed together.
The 300mW-class output power provides a useful medium-power VCSEL option for compact 940nm optical source designs, especially where stronger pulse optical output, multi-emitter layout, 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 medium-power sensing, pulse illumination, machine vision support, industrial optical detection, and compact VCSEL source projects, bare die mounting, ceramic submount assembly, chip-on-board integration, wire bonding, beam shaping, drive condition review, or customized package discussion is available according to the project requirements.
