Product Overview
1. Standard Bare Die VCSEL for Ultra-High-Power 850nm NIR Illumination
This 850nm 6W VCSEL bare die is designed for ultra-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 6W-class optical output power and 5.5W typical output at IF = 7A, this device provides a high-output 850nm VCSEL source for applications requiring strong NIR illumination, multi-emitter die structure, thermal design review, and compact bare die assembly flexibility.
2. Key Features
This 850nm 6W VCSEL bare die is supplied as a standard ultra-high-power multi-emitter VCSEL chip for NIR illumination and optical source applications.
Key features include 850nm typical wavelength, 6W-class optical output power, 5.5W typical output at IF = 7A, 1273-emitter bare die structure, 10±1μm emitting aperture, 38% typical power conversion efficiency, 19° 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 ultra-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 6W-class output power provides a useful high-output source option for compact optical path design, especially where strong NIR illumination, pulse operation, multi-emitter die layout, thermal design review, or customized VCSEL package development is required.
