665nm / 940nm Dual-Wavelength VCSEL SMD for Reflective PPG Optical-System Evaluation
The 665nm 5.5mW / 940nm 7mW Dual-Wavelength VCSEL SMD 7015 combines a visible red 665nm channel and a 940nm infrared channel in a compact surface-mount package. It is intended for component-level evaluation of reflective optical systems and PPG-oriented OEM assemblies where channel output, package geometry, drive interface, and optical coupling must be verified together.
The source specifies a 2.0 × 0.8 × 0.75mm 7015 package, water-clear encapsulation, CW test conditions, and a 20° typical FWHM beam divergence for both channels. The 665nm channel is 5.5mW typical at 15mA, and the 940nm channel is 7mW typical at 10mA. These are component test conditions, not a finished-device signal-quality, SpO2, accuracy, or clinical-performance specification.
Multi-Wavelength Optical Configuration and Channel Selection
The package combines one red and one infrared VCSEL channel for reflective optical-system evaluation. The 665nm channel is specified at 4–7mW with 5.5mW typical output at 15mA. The 940nm channel is specified at 6–8mW with 7mW typical output at 10mA. The channels use different test currents and should be measured independently.
Selection for a PPG-oriented assembly should consider the customer's optical geometry, detector response, channel timing, drive current, beam distribution, mechanical placement, optical coupling, ambient-light control, and algorithm validation plan. The emitter package alone does not establish signal quality, SpO2 accuracy, algorithm performance, medical efficacy, or finished-device compliance.
7015 Package, Electrical Interface and PCB Integration
The 7015 package uses a common-anode layout with separate red and infrared cathodes. The water-clear encapsulation and source-specified 20° typical FWHM divergence should be considered when evaluating optical-axis placement, beam overlap, diffuser or lens coupling, and detector geometry.
Before PCB release, verify the common-anode connection, separate channel current control, pad layout, reflow profile, package orientation, thermal path, optical measurement method, and mechanical clearance. Similar package dimensions or channel names do not by themselves prove pin compatibility or drop-in replacement status for another emitter.
Reflective PPG Optical-System Evaluation and Custom Integration
This 7015 configuration can be evaluated as a dual-wavelength component within a reflective PPG optical system. The relevant engineering work includes red/infrared channel timing, current control, optical coupling, detector placement, ambient-light management, mechanical alignment, thermal behavior, and validation of the customer's signal-processing chain.
The released 665nm 5.5mW / 940nm 7mW configuration is the standard specification described by this page. If a project needs another output selection, wavelength combination, electrical interface, package layout, or integrated detector arrangement, those requirements must be reviewed as a project-specific custom configuration. The component does not establish a finished-device health measurement, SpO2 result, clinical claim, certification, or direct replacement for another 7015 part.
Evaluation, Documentation and Custom Development Support
For component-level evaluation, review the released datasheet together with the customer's driver, detector, PCB, optical coupling, thermal, and algorithm requirements. An Evaluation Kit with 10 pcs / KIT is available for checking separate red/infrared output, common-anode drive compatibility, package footprint, optical geometry, and early system-level PPG evaluation.
Before production integration, confirm the applicable electrical limits, CW test conditions, soldering profile, ESD handling, optical measurement method, detector path, and customer-system exposure conditions against the current technical documentation. Documentation applies to the component configuration and does not certify the customer's finished device.
Frequently Asked Questions
What are the output conditions for the 665nm and 940nm channels?
The 665nm channel is specified at 4–7mW with 5.5mW typical output at 15mA. The 940nm channel is specified at 6–8mW with 7mW typical output at 10mA. The channels use separate test-current conditions and should be evaluated independently.
How is the 7015 electrical interface arranged?
The source specifies a common-anode layout with separate red and infrared cathodes. The customer's driver and PCB must still verify pin marking, current control, forward voltage, thermal behavior, reflow conditions, and optical alignment for the complete assembly.
Does this package guarantee PPG or SpO2 performance?
No. It is a component-level red/infrared VCSEL SMD for reflective optical-system evaluation. Signal quality, SpO2 accuracy, algorithm performance, medical claims, and finished-device compliance depend on the customer's complete optical, electrical, mechanical, and software system.
