Product Overview
1. Bare Die Supply for Engineering Evaluation
This 665nm 8mW VCSEL bare die is designed for 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 an 8mW-class red VCSEL output and 4-emitter design, this product is suitable for higher-output red-light module evaluation while keeping a compact bare-die footprint. It can be used for beauty device development, face mask optical validation, hair-growth device evaluation, photobiomodulation-related product testing, sensing systems, machine vision support, and compact optical modules.
Compared with lower-power single-emitter VCSEL chips, this 4-emitter design is more suitable for customers who need stronger red-light output during prototype validation, multi-emitter optical layout evaluation, package-level thermal observation, and early-stage module integration before customized array development.
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.
