850nm / 940nm Dual-Wavelength VCSEL SMD for Compact NIR Optical-System Development
The 850nm / 940nm Dual-Wavelength VCSEL SMD 3528 combines two near-infrared VCSEL channels in one compact surface-mount package. It is intended for component-level evaluation of compact NIR optical systems where the customer's driver, optical geometry, detector path, mechanical placement, and signal-processing requirements must be validated together.
The source specifies an 850nm channel and a 940nm channel in a 3528 SMD package, CW test conditions, and a 25° beam divergence. Each channel is specified at 6.5mW minimum and 8mW typical output at 10mA. These are component test conditions and do not define a finished-device sensing result, measurement accuracy, clinical performance, or regulatory approval.
Multi-Wavelength Optical Configuration and Channel Selection
The two VCSEL channels provide 850nm and 940nm near-infrared output from one 3528 SMD package. At the source-stated 10mA test current, the 850nm channel is specified at 6.5mW minimum and 8mW typical output, and the 940nm channel is specified at 6.5mW minimum and 8mW typical output. The source does not state maximum optical-output values for these channels, so no maximum value is added here.
Selection for a compact optical assembly should consider the customer's optical geometry, detector response, channel timing, drive current, beam distribution, mechanical placement, optical coupling, ambient-light control, thermal behavior, and signal-processing validation plan. The two wavelength channels do not by themselves establish a completed sensing function or performance result.
3528 Package, Electrical Interface and PCB Integration
The 3528 surface-mount package is intended for compact PCB-level optical integration. Before layout release, verify the source pin definition, channel-current control, pad layout, package orientation, reflow profile, thermal path, optical measurement method, and mechanical clearance against the current technical documentation.
Package size and wavelength labels alone do not prove pin compatibility, optical-axis alignment, or drop-in replacement status for another dual-wavelength emitter. The customer's complete assembly must be evaluated with its actual driver, detector, optical path, and mechanical stack-up.
Compact NIR Optical-System Evaluation and Custom Integration
This 850nm / 940nm configuration can be evaluated as a compact dual-wavelength VCSEL SMD component in an NIR optical system. Relevant engineering work includes independent channel drive, optical coupling, detector placement, ambient-light management, mechanical alignment, thermal behavior, and validation of the customer's signal-processing chain.
The released 850nm / 940nm 3528 configuration is the standard specification described by this page. If a project needs another wavelength combination, optical-output selection, electrical interface, package layout, or integrated optical arrangement, those requirements must be reviewed as a project-specific custom configuration. The component does not establish a finished-device measurement result, medical claim, certification, or direct replacement for another 3528 part.
Evaluation, Documentation and Custom Development Support
For component-level evaluation, review the released datasheet together with the customer's driver, PCB, detector, optical coupling, thermal, and signal-processing requirements. An Evaluation Kit with 10 pcs / KIT is available for checking dual-channel drive compatibility, package footprint, optical geometry, thermal behavior, and compact NIR optical-system integration.
Before production integration, confirm the applicable electrical limits, CW test conditions, soldering profile, ESD handling, optical measurement method, detector path, thermal conditions, 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 specified output conditions for the 850nm and 940nm channels?
Both channels are specified at 6.5mW minimum and 8mW typical output at 10mA under the source-stated CW test condition. Maximum optical-output values are not stated in the source specification.
What package is used for this dual-wavelength VCSEL?
The product uses a 3528 surface-mount package with 850nm and 940nm VCSEL channels. The customer's PCB designer must verify the current pin definition, pad layout, package orientation, reflow profile, and optical alignment against the latest documentation.
Does this component guarantee a completed NIR sensing result?
No. It is a component-level dual-wavelength VCSEL SMD for optical-system evaluation. Finished-device output, detector response, measurement accuracy, algorithm performance, safety, and regulatory status depend on the customer's complete electrical, optical, mechanical, thermal, and software implementation.
