1. 460nm LED / 660nm VCSEL SMD 2835 for Dual-Channel Optical-Source Integration
This 2835 SMD combines one 460nm LED channel with one 660nm VCSEL channel for compact dual-channel optical-source integration on an OEM PCB. It is a component-level emitter configuration: the source identifies the LED and VCSEL channels separately, with their own stated electrical and optical test conditions.
The 460nm LED is specified by luminous intensity, while the 660nm VCSEL is specified by optical output power. These different measurement bases should be retained during optical-system evaluation rather than converted into a direct output equivalence.
2. Multi-Wavelength Optical Configuration and Channel Selection
At CW operation, the source specifies the 660nm VCSEL at 4.8-5.2mW with IF=10mA and an 18° full-angle divergence at CW, IF=10mA and Ta=25°C. The 460nm LED is specified at 400-600mcd with IF=20mA and a 120° full viewing angle at CW, IF=20mA.
Select this configuration when the optical architecture requires the specific 460nm LED and 660nm VCSEL channel combination in a 2835 SMD. Final channel drive, optical coupling and thermal conditions must be validated in the completed design.
3. 2835 Package, Electrical Interface and PCB Integration
The source identifies an 2835 SMD package with a 7mil × 7mil chip specification. Package layout, assembly process, thermal path and optical coupling should be evaluated against the customer PCB and downstream optical architecture.
The source states that reverse drive of the VCSEL channel is prohibited. Current limiting and ESD protection are required in the final design.
4. OEM Optical-Source Development and Custom Integration
This dual-channel LED and VCSEL SMD is intended for OEM optical-source development where channel selection, drive conditions, package integration and optical coupling are evaluated as part of a completed system. Submit the target wavelength role, optical path, PCB constraints and operating conditions for engineering review.
5. Evaluation, Documentation and Custom Development Support
This 460nm LED / 660nm VCSEL SMD 2835 is available as an Evaluation Kit with 10 pcs / KIT for early-stage comparison of channel drive, optical coupling, emission profile and PCB integration.
For component-level project evaluation, an Initial Product Report covering the Laser Diode Series and VCSEL Laser Diode Chip Series has been filed with the U.S. FDA CDRH. This filing supports technical documentation and product evaluation.
For applicable products, CE, EMC, EN 60825, LVD, RoHS, REACH and halogen-free certification and compliance documents are available. Documentation depends on the corresponding product model and does not represent certification of the customer's finished device.
6. Frequently Asked Questions
Can the 460nm LED and 660nm VCSEL outputs be compared directly?
No. The source specifies the 460nm LED in luminous intensity and the 660nm VCSEL in optical output power. Their stated measurement bases, drive conditions, optical path and final system requirements should be evaluated separately.
What are the source-stated optical values for the 660nm VCSEL channel?
The source specifies 4.8-5.2mW at CW, IF=10mA, with an 18° full-angle divergence at CW, IF=10mA and Ta=25°C. Final optical performance depends on the completed system design.
What electrical precautions apply to the 660nm VCSEL channel?
The source prohibits reverse drive of the VCSEL channel and requires current limiting and ESD protection in the final design.
