1. 650nm VCSEL SMD Series for TO-5.6 Replacement and Hair-Growth Device Development
The 650nm 5mW VCSEL SMD Series includes visible-red laser devices supplied in five surface-mount package options: 1615, 2835, 3030, 3535 and 5050. The series provides a typical optical output power of 5.5mW.
It is a surface-mount alternative to conventional 650nm 5mW TO-5.6 laser diodes and legacy 650nm SMD laser diodes. Primary applications include laser hair-growth caps, hair-growth helmets, laser combs, scalp photobiomodulation systems and other compact red-light products.
All models use a multi-mode VCSEL structure, operate in CW mode and produce an annular, donut-shaped beam spot. The range of package sizes allows developers to select an option according to PCB space, emitter spacing, product thickness and automated assembly requirements.
2. Core Optical Specifications and Package Options
The 650nm VCSEL SMD Series has a typical center wavelength of 650nm and a specified wavelength range of 640–660nm.
Typical optical output power is 5.5mW, with a specified output range of 5.0–7.2mW at 10mA. The series operates in CW mode and has a typical beam divergence of 25°.
Optical Output Power | Package | Package Material | Operating Mode | Beam Divergence |
|---|---|---|---|---|
5.5mW typ. | 1615 | PCT | CW | 25° typ. |
5.5mW typ. | 2835 | PCT | CW | 25° typ. |
5.5mW typ. | 3030 | PCT | CW | 25° typ. |
5.5mW typ. | 3535 | Ceramic | CW | 25° typ. |
5.5mW typ. | 5050 | PCT | CW | 25° typ. |
The 1615 package supports compact designs with strict PCB-area and product-thickness limits.
The 2835 and 3030 packages are suitable for standard automated placement and multi-laser PCB layouts.
The 3535 ceramic package supports product structures requiring a ceramic base.
The 5050 package provides a larger assembly platform for different PCB and mechanical configurations.
3. Surface-Mount Alternative to Conventional 650nm TO-5.6 and Legacy SMD Laser Diodes
The 650nm VCSEL SMD Series provides a surface-mount alternative to conventional 650nm 5mW TO-5.6 laser diodes and legacy SMD laser diodes.
Traditional TO-5.6 laser diodes commonly require manual lead insertion, lead positioning, lead trimming and secondary soldering. They also occupy more vertical space inside the finished product.
VCSEL SMD devices can be mounted directly onto the PCB surface, supporting lower-profile products, dense optical-source layouts and automated volume manufacturing.
The series can be used in product designs previously based on the following device types and models:
- HGLD-650TO5.6-JP-5mW and similar 650nm 5mW TO-5.6 laser diodes
- LECC LS65050001 and similar legacy 650nm SMD laser diodes
- QSI QL65D5 and QL65D7 Series 650nm 5mW TO-56 laser diodes
- ADL65052TL and similar conventional 650nm laser diodes
- Other 650nm 5mW laser diodes used in hair-growth caps, helmets, combs and red-light devices
The five SMD package options support different product dimensions, PCB layouts and emitter-spacing requirements, allowing manufacturers to move from conventional leaded laser structures to surface-mount designs.
4. SMT Automation and Cost Advantages
Compared with conventional 650nm TO-5.6 laser diodes, the 650nm VCSEL SMD Series offers a lower component cost and reduces total processing and assembly costs through automated SMT placement and reflow production.
Key manufacturing advantages include:
- Compatible with standard SMT placement equipment
- Supports automated pick-and-place processing
- Suitable for volume PCB assembly
- Supports reflow soldering
- No manual lead insertion
- No lead trimming or forming
- Reduced secondary soldering processes
- Lower manual assembly cost
- Lower-profile product structures
- Improved volume-production consistency
- Suitable for scalable manufacturing and dense multi-laser layouts
For hair-growth caps, helmets and wearable devices containing dozens or hundreds of laser sources, the surface-mount structure can simplify production and improve PCB assembly efficiency.
5. Applications
Laser Hair-Growth Caps and Helmets
The 650nm VCSEL SMD Series is suitable for laser hair-growth caps, hair-growth helmets and other multi-point scalp-light products.
The 1615, 2835, 3030, 3535 and 5050 packages support different emitter spacing, PCB dimensions and finished-product thickness requirements.
Laser Combs and Hair-Growth Bands
Compact SMD packages can be integrated directly onto rigid or flexible PCBs for laser combs, hair-growth bands and localized scalp-light devices.
The surface-mount structure reduces the internal space required by conventional TO-can packages.
Scalp Photobiomodulation Systems
The series can be used in 650nm scalp photobiomodulation devices, scalp-care equipment and red-light prototype systems.
Multiple VCSEL devices can be arranged on PCBs with different shapes and dimensions.
Localized Red-Light PBM and Personal-Care Devices
The 650nm VCSEL SMD Series can also be used in localized red-light PBM devices, personal-care products, compact beauty equipment and wearable red-light systems.
Visible-Red Optical Systems
The series can also support visible-red optical modules, indication systems, alignment equipment and laboratory light-source systems.
