Product Overview
1. Standard Bare Die VCSEL for 850nm CW NIR Illumination
This 850nm 2W CW VCSEL bare die is designed for continuous-wave near-infrared illumination, machine vision auxiliary lighting, industrial optical sensing, high-power NIR source modules, and custom VCSEL integration projects.
The product is supplied as a standard bare die device by default. It is suitable for CW NIR illumination modules, machine vision light source development, industrial sensing systems, compact high-power optical source designs, and chip-level VCSEL module integration.
With 2W-class optical output power and 2.1W typical output at IF = 2.2A, this device provides a high-power 850nm VCSEL source for applications requiring stable continuous-wave operation, stronger NIR output, and compact bare die assembly flexibility.
2. Key Features
This 850nm 2W CW VCSEL bare die is supplied as a standard high-power VCSEL chip for continuous-wave NIR illumination and optical source applications.
Key features include 850nm typical wavelength, 2W-class CW optical output power, 2.1W typical output at IF = 2.2A, 43% typical power conversion efficiency, 22° 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, CW 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 CW NIR illumination, machine vision auxiliary lighting, industrial detection, active optical illumination, high-power VCSEL module development, and custom NIR optical source integration.
In a CW illumination or high-power sensing module design, the VCSEL wavelength, output power, drive current, thermal path, package structure, beam profile, detector response, optical path, and final system signal behavior should be reviewed together.
The 2W-class CW output power provides a useful high-power source option for compact optical path design, especially where stable continuous-wave operation, thermal design review, high optical output, or customized VCSEL package development is required.
