Product Overview
1. Standard VCSEL Bare Die for 940nm 100mW Pulse NIR Sensing
This 940nm 100mW 10Mil VCSEL bare die is designed for pulse near-infrared sensing, active illumination, optical detection, machine vision support, 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, proximity detection, active illumination systems, industrial optical detection, and chip-level VCSEL integration projects.
With 115mW typical optical output power at IF = 140mA, this device provides a compact 940nm VCSEL source for applications requiring higher optical output than low-power single-emitter devices while maintaining a small die-level format.
2. Key Features
This 940nm 100mW 10Mil VCSEL bare die is supplied as a standard pulse-power VCSEL device for NIR sensing and active illumination applications.
Key features include 940nm typical wavelength, 100mW-class optical output power, 23-emitter VCSEL layout, 2.0V typical forward voltage, 41% typical power conversion efficiency, 21° typical beam divergence at 1/e², and doughnut-shaped symmetrical far-field output.
The compact 245μm × 239μm die size and 23-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 pulse NIR sensing, active illumination, optical detection, machine vision support, industrial sensing, and custom VCSEL source integration.
In a compact pulse sensing or active illumination module design, the VCSEL wavelength, output power, drive current, forward voltage, package structure, thermal path, beam profile, detector response, optical path, and final system signal behavior should be reviewed together.
The 100mW-class output power provides a useful intermediate VCSEL option for compact 940nm optical source designs, especially where higher pulse optical output, small die size, multi-emitter layout, 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 pulse sensing, active 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.
