Vixar is pleased to announce the release of a family of high power VCSEL products including diffuser and monitor photodiode. The product line is based upon a surface mountable ceramic package and is designed to serve the consumer, industrial and medical 3D imaging and sensing market.
The addition of the photodiode monitor is useful for controlling output power levels, and for monitoring for events which can affect eye safety. By combining the photodiode monitoring with the appropriate threshold circuit, one can detect events that can create an eye safety hazard, such as a broken, missing or damaged diffuser.
The product family encompasses a number of options including: 850nm/940nm wavelength, power levels from 0.3W to 4W, multiple ceramic package sizes from 1.9mmx2.2mm to 2.8mmx3.5mm, options with or without monitor diode, and a variety of diffuser designs.
Performance, reliability and manufacturability are intrinsic to the designs which are being produced on a high-volume manufacturing line.
VCSELs provide advantages over both Light Emitting Diodes and conventional lasers in terms of their speed (for Time of Flight applications), narrow spectrum (for compatibility with filters used to reduce the effect of ambient light, and compact packaging.
Vixar’s full product lineup of VCSELs with wavelengths ranging from 660nm to 940nm, provides our customers with great flexibility in tailoring solutions to optimize for visibility, compatibility with detectors, and desired spectral and beam divergence characteristics.
Please contact us with your specific needs and requirements and we will help to craft the optimum solution for your application.
Mr. Todd Schieffert
