For CW applications, the 1W CW and 2W CW versions should be selected separately from pulse-power versions. For high-power pulse applications, the 1.5W, 2W pulse, 3W, and 6W versions can be reviewed according to optical power, duty cycle, thermal path, and package-level integration requirements.
3. Application Development Direction
This 850nm VCSEL bare die series supports NIR sensing, proximity sensing, machine vision illumination, industrial optical detection, active NIR illumination, consumer electronics optical sensing, and custom optical source module development.
For sensing and illumination systems, the VCSEL wavelength, output power, drive current, operating mode, duty cycle, thermal path, package structure, beam profile, optical path, detector response, and final system signal behavior should be reviewed together.
For low-power sensing projects, lower-current devices such as the 5mW, 20mW, 30mW, 70mW, or 100mW versions may be suitable. For machine vision and industrial illumination, 200mW, 300mW, 400mW, 500mW, 1.5W, 2W pulse, 3W, or 6W versions can be reviewed. For stable continuous-wave operation, the 850nm 1W CW and 850nm 2W CW VCSEL bare die options should be selected separately from pulse-power versions.
