1. 660nm 5mW Single-Emitter VCSEL Bare Die for Compact Red-Light Optical Integration
This 660nm 5mW single-emitter VCSEL bare die is a compact component for red-light optical integration, visible-indicator development and OEM optical modules. The released source specifies 5.0mW typical optical output power at 10mA in continuous-wave operation and a typical die size of 200µm x 200µm x 100µm.
Its single-emitter configuration gives optical engineers a defined emitter aperture for custom collection, coupling and beam-shaping evaluation. The final focused spot, delivered power and system performance depend on the completed optical design and must be validated at module level.
2. 660nm Wavelength, 5mW Output and CW Test Conditions
At 10mA, CW operation and 25°C, the source specifies a 650nm / 660nm / 670nm wavelength range for minimum, typical and maximum values. Optical output power is specified as 5.0mW typical at the same 10mA, CW and 25°C test condition.
The released electrical table states 2.2V / 2.6V / 3.0V laser forward voltage at 10mA and 25°C for minimum, typical and maximum values. Threshold current is specified as 3.5mA typical, and the typical operating current is 7.5mA. Use the stated source conditions when comparing candidate drive circuits.
3. Single-Emitter Die Structure, Divergence and Integration Parameters
The source gives the die dimensions as 185µm / 200µm / 215µm in both length and width and 90µm / 100µm / 110µm in height for minimum, typical and maximum values. It is supplied as a bare die for application-specific attachment, wire bonding, optical alignment and package development.
Beam divergence is specified as 20° typical and 26° maximum, D86, at 10mA, CW and 25°C. D86 describes the angle containing 86% of the emitted optical power; it does not by itself define the final focused spot of an OEM assembly.
4. Compact Red-Light Source and Visible-Indicator Development
The released product overview identifies compact red-light-source and visible-indicator directions. The single-emitter bare die can be assessed where the OEM controls the optical aperture, coupling elements, mechanical stack-up and final power budget rather than selecting a finished laser module.
For projects with strict optical-placement or beam-shaping requirements, validate die attach, bond-wire geometry, drive current, thermal path, lens selection and final optical output together. This page describes a component for OEM development; it does not represent a finished device or a guaranteed system beam profile.
5. Evaluation, Documentation and Custom Development Support
For qualified component-level evaluation, a 10 pcs / KIT sample path can be discussed together with the datasheet, the stated 10mA CW test condition and the intended optical-integration direction. Confirm die attach, drive current, package concept and final optical requirements before selecting a production configuration.
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
FAQ 1. How Is the 5mW Optical Output Specified for This 660nm Single-Emitter VCSEL Bare Die?
The source specifies 5.0mW typical optical output power at 10mA, CW operation and 25°C. Treat this as a source test condition rather than a guaranteed delivered-power value after die attachment, optics, thermal design and system losses.
FAQ 2. Does the D86 Value Define the Final Focused Spot of an OEM Optical Module?
No. The source specifies 20° typical and 26° maximum D86 beam divergence at 10mA, CW and 25°C. The final focused spot also depends on the mounting reference, package geometry, lens selection, alignment, drive condition and complete optical system.
FAQ 3. Is This 660nm Single-Emitter VCSEL Bare Die a Finished-Device Laser-Safety Classification?
No. The release source includes a Class 3R safety warning label for the bare-die component. The final device's accessible-emission level, safety classification, labeling and regulatory status must be assessed by the OEM for the completed product.
