Product Overview
1. Standard VCSEL Bare Die for 940nm High-Power NIR Illumination
This 940nm 1.5W VCSEL bare die is designed for high-power near-infrared illumination, industrial sensing, active optical detection, machine vision support, and custom VCSEL source module development.
The product is supplied as a standard VCSEL bare die by default. It is suitable for 940nm high-power pulse sensing modules, active NIR illumination, industrial optical detection, machine vision auxiliary lighting, and chip-level VCSEL integration projects.
With 1.65W typical optical output power at IF = 2A, this device provides a high-power 940nm VCSEL source for applications requiring stronger NIR output, multi-emitter bare die integration, and compact optical module design.
2. Key Features
This 940nm 1.5W VCSEL bare die is supplied as a standard high-power pulse VCSEL device for NIR illumination and sensing applications.
Key features include 940nm typical wavelength, 1.5W-class optical output power, 280-emitter VCSEL layout, 2.1V typical forward voltage, 40% typical power conversion efficiency, 21° typical beam divergence at 1/e², and doughnut-shaped symmetrical far-field output.
The 885μm × 810μm die size and multi-emitter layout 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, 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 NIR illumination, industrial sensing, active optical detection, machine vision support, high-power VCSEL module development, and custom optical source integration.
In a high-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 1.5W-class output power provides a practical high-power VCSEL option for 940nm optical source designs, especially where stronger pulse optical output, multi-emitter layout, 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 NIR illumination, industrial sensing, machine vision support, active optical detection, and custom VCSEL source projects, bare die mounting, ceramic submount assembly, chip-on-board integration, wire bonding, beam shaping, thermal design review, drive condition review, or customized package discussion is available according to the project requirements.
