Product Overview
1. Standard VCSEL Bare Die for 940nm High-Efficiency NIR Sensing and Illumination
This 940nm 800mW VCSEL bare die is designed for high-efficiency pulse near-infrared sensing, active illumination, industrial optical detection, machine vision support, and compact optical source development.
The product is supplied as a standard VCSEL bare die by default. It is suitable for 940nm pulse sensing modules, active NIR illumination, optical detection systems, industrial sensing modules, machine vision auxiliary lighting, and chip-level VCSEL integration projects.
With 830mW typical optical output power at IF = 0.5A, this device provides a high-efficiency 940nm VCSEL source for applications requiring strong pulse output, compact die-level integration, and efficient near-infrared optical emission.
2. Key Features
This 940nm 800mW VCSEL bare die is supplied as a standard high-efficiency pulse VCSEL device for NIR sensing and active illumination applications.
Key features include 940nm typical wavelength, 800mW-class optical output power, 44-emitter VCSEL layout, 14±1μm emitting aperture, 3.4V typical forward voltage, 52% typical power conversion efficiency, 29° typical beam divergence at 1/e², and doughnut-shaped symmetrical far-field output.
The 785μm × 395μm die format and high-efficiency 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 high-efficiency NIR sensing, pulse illumination, active optical detection, industrial sensing, machine vision support, and custom VCSEL source integration.
In a high-efficiency pulse 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 800mW-class output power provides a useful high-efficiency VCSEL option for compact 940nm optical source designs, especially where strong pulse optical output, efficient electrical-to-optical conversion, 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-efficiency 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.
