Product Overview
1. Bare Die Supply for Engineering Evaluation
This 665nm 3mW VCSEL bare die is designed for low-power red-light optical system development, especially for engineering teams working on bare-die integration, package validation, and early-stage product evaluation.
We support development-stage bare die supply, helping customers evaluate wire bonding, ceramic submount assembly, PCB-level optical integration, and custom laser packaging feasibility before larger-volume planning.
2. Application Development Direction
With a 3mW-class red VCSEL output and single-emitter design, this product is better suited for low-power optical validation rather than high-irradiance module development. It is suitable for early-stage red-light prototype testing, compact beauty device evaluation, sensor light sources, machine vision support, and small optical module development.
For photobiomodulation-related products or compact red-light systems, this bare die can help engineering teams verify wavelength suitability, drive conditions, wire bonding process, and package-level optical performance before moving to higher-power or multi-emitter configurations.
If the standard configuration does not fully match the project requirement, custom wavelength, output power, emitter configuration, chip layout, and package-level solutions can also be discussed based on the specific application.
3. 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.
BestLaser Opto Component Device Limited has filed an Initial Product Report with the U.S. FDA CDRH for the Laser Diode Series, including the VCSEL Laser Diode Chip Series. CE-related documentation is also available for project evaluation, including EMC documentation and EN 60825 laser safety / LVD test documentation. Material compliance documentation, including RoHS, REACH, and HF documentation, can also be provided upon request.
