1. 680nm 5/34mW VCSEL SMD Series for Hair-Growth and Red-Light Device Development
The 680nm 5/34mW VCSEL SMD Series includes visible-red surface-mount laser devices with two optical power options and three package configurations: 5mW in 2835 and 5730 packages, and 34mW in a 3030 package.
The series is designed primarily for the development and evaluation of laser hair-growth helmets, laser caps, scalp photobiomodulation systems, localized red-light PBM devices and wearable personal-care products.
All models use a multi-mode VCSEL structure and produce an annular, donut-shaped beam spot. The SMD packages support compact PCB layouts, automated placement, reflow assembly and multi-VCSEL optical layouts.
These are component-level products. The application descriptions on this page do not represent claims regarding the medical efficacy, clinical performance or regulatory approval of any finished device.
2. Model Selection and Core Optical Specifications
The 680nm VCSEL SMD Series provides two optical power options and three package formats. Developers can select a model according to peak optical output, package dimensions, pad configuration, beam divergence and PCB layout requirements.
Optical Output Power | Package | Wavelength Range | Beam Divergence | Operating Condition |
|---|---|---|---|---|
5mW typ. | 2835 | 673–687nm | 22° typ. | QCW, 0.5ms pulse width, 1% duty cycle |
5mW typ. | 5730 | 675–685nm | 19° typ., 23° max. | QCW, 0.5ms pulse width, 1% duty cycle |
34mW typ. | 3030 | 670–690nm | 25° typ. | QCW, 0.5ms pulse width, 1% duty cycle |
All three models have a typical center wavelength of 680nm and produce an annular beam profile.
Developers should evaluate emitter spacing, working distance, beam overlap and target-area geometry to determine the irradiance distribution of the complete optical system.
The 34mW 3030 model provides higher peak optical output under QCW operating conditions and can be evaluated for pulsed systems and prototypes requiring higher peak output.
The 34mW value does not represent continuous-wave average optical power and should not be interpreted as a higher therapeutic dose or improved finished-device performance. Models must be compared under equivalent driving conditions, duty cycle and optical-system configurations.
3. Package Selection and PCB Integration
2835 Package
The 680nm 5mW 2835 VCSEL SMD is suitable for compact rigid or flexible PCB layouts. It can be evaluated for laser caps, scalp-light modules and wearable devices with limited internal space.
5730 Package
The 680nm 5mW 5730 VCSEL SMD provides a larger package and assembly platform with integrated Zener protection.
It can support PCB designs requiring a larger pad structure, a different mechanical layout or additional component-level protection.
3030 Package
The 680nm 34mW 3030 VCSEL SMD uses a compact square package and is intended for localized red-light systems, optical modules and multi-channel prototypes requiring higher peak output under QCW conditions.
The three packages have different dimensions, pad structures and electrical configurations. Customers should use the corresponding datasheet to validate the PCB footprint, polarity, driving circuit, thermal design and reflow process.
4. Applications
Laser Hair-Growth Helmets and Caps
The 680nm 5mW models can be evaluated for laser hair-growth helmets, laser caps and other wearable scalp-light systems.
Device engineers can design multi-point laser layouts according to the product area, VCSEL quantity, emitter spacing, working distance and driving mode.
Scalp Photobiomodulation Systems
The series can be used for optical evaluation, prototype development and engineering validation of 680nm scalp photobiomodulation systems.
System developers must independently validate irradiance, optical dose, operating time, temperature rise, emitter spacing and the laser safety classification of the finished device.
Laser Combs and Localized Scalp-Light Devices
For laser combs, localized scalp-light products and small-area directional light sources, developers can select the 5mW or 34mW model according to package size, peak output and optical-layout requirements.
Localized Red-Light PBM and Personal-Care Devices
The 680nm VCSEL SMD Series can also be evaluated for localized red-light PBM devices, wearable red-light products, beauty and personal-care equipment and custom multi-channel red-light prototypes.
PBM application references indicate component-level development possibilities only and do not represent validation of any specific therapeutic effect.
Biophotonic and Visible-Red Optical Research
Where the annular beam profile, beam divergence and QCW operating conditions are compatible with the system design, the series may also be evaluated for biophotonic research, plant photobiology experiments, visible-red optical sensing, optical alignment and laboratory illumination equipment.
For precision detection or research applications, customers should independently validate spectral characteristics, power stability, modulation conditions, target response and complete optical-path performance.

6. Frequently Asked Questions
FAQ 1. What power and package options are available in the 680nm VCSEL SMD Series?
The series includes two typical optical power options and three SMD packages:
- 5mW typ. in a 2835 package
- 5mW typ. in a 5730 package
- 34mW typ. in a 3030 package
All three models have a typical center wavelength of 680nm and use an annular, donut-shaped beam profile under QCW operating conditions.
FAQ 2. How should developers select between the 5mW and 34mW models?
The 5mW models are suitable for low-power multi-point layouts, wearable scalp devices and compact PCB designs.
The 34mW 3030 model provides higher peak optical output under QCW conditions and can be evaluated for pulsed red-light systems, localized optical sources and prototypes requiring higher peak output.
The 34mW value does not represent higher continuous average power or stronger therapeutic performance. Model selection must consider pulse width, duty cycle, VCSEL quantity, working distance, optical dose and complete-device safety requirements.
FAQ 3. Can the 680nm VCSEL SMD Series be used in laser hair-growth and scalp PBM devices?
The series can be evaluated for the development and prototyping of laser hair-growth helmets, laser caps, laser combs, localized scalp-light systems and scalp PBM equipment.
Finished-device developers must independently validate driving conditions, VCSEL quantity, working distance, irradiance distribution, optical dose, temperature rise and laser safety classification.
Supplying the component does not mean that the finished device has completed medical-effect validation or regulatory certification.
