Product Overview
1. Standard Bare Die VCSEL for High-Power 850nm NIR Illumination
This 850nm 3W VCSEL bare die is designed for high-power near-infrared illumination, machine vision auxiliary lighting, industrial optical sensing, active NIR illumination, high-power optical source modules, and custom VCSEL integration projects.
The product is supplied as a standard bare die device by default. It is suitable for high-power NIR illumination modules, machine vision light source development, industrial sensing systems, active optical detection, compact high-power source designs, and chip-level VCSEL module integration.
With 3W-class optical output power and 3.5W typical output at IF = 4A, this device provides a high-power 850nm VCSEL source for applications requiring strong NIR output, multi-emitter die structure, and compact bare die assembly flexibility.
2. Key Features
This 850nm 3W VCSEL bare die is supplied as a standard high-power multi-emitter VCSEL chip for NIR illumination and optical source applications.
Key features include 850nm typical wavelength, 3W-class optical output power, 3.5W typical output at IF = 4A, 624-emitter bare die structure, 37% typical power conversion efficiency, 21° typical beam divergence at 1/e², stable central wavelength, and doughnut-shaped symmetrical far-field output.
The bare die format allows flexible integration into ceramic submounts, thermally optimized chip-on-board assemblies, compact optical modules, high-power NIR source modules, and customer-specific VCSEL packages.
Package-level assembly, wire bonding, ceramic submount mounting, thermal path design, pulse 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 850nm high-power NIR illumination, machine vision auxiliary lighting, industrial detection, active optical illumination, high-power VCSEL module development, and custom NIR optical source integration.
In a high-power illumination or sensing module design, the VCSEL wavelength, output power, drive current, duty cycle, thermal path, package structure, beam profile, detector response, optical path, and final system signal behavior should be reviewed together.
The 3W-class output power provides a useful high-power source option for compact optical path design, especially where strong NIR output, pulse operation, thermal design review, or customized VCSEL package development is required.
4. Evaluation Sample Kit and Documentation Support
Evaluation Sample Kit: USD 29 / KIT, 10 PCs / KIT. International express shipping is typically USD 69–89 depending on destination.
