1. 650nm 5mW Adjustable-Focus EEL Laser Module for OEM Red-Dot Integration
The 650nm 5mW Adjustable-Focus EEL Laser Module is a compact red laser source for OEM teams integrating visible red-dot projection, positioning or indication into finished products. It uses an edge-emitting laser diode (EEL), provides 5mW rated optical output at a nominal wavelength of 650nm, and is supplied in a 6mm copper housing with a front lens barrel.
The module is a component for integration rather than a finished consumer laser product. Its adjustable-focus mechanism lets the OEM team set the required spot size and beam divergence during system development; a fixed-focus configuration can also be factory-set and secured before shipment.
Typical integration directions include:
- Smart toys and interactive products that need visible red-dot projection, positioning or indication.
- RC models and electronic toys that use a compact red laser spot for visual feedback or target indication.
- Compact consumer and display products that require an adjustable spot size or factory-fixed focus.
The final-system laser classification, accessible emission and market compliance must be evaluated by the system designer for the final product structure and intended use.
2. Adjustable-Focus Optical Configuration and Projection Control
The focusing mechanism can be rotated to adjust the output spot size and beam divergence. This allows the same 650nm red laser module platform to be evaluated for different working-distance, indication and visual-feedback requirements during OEM development.
The specification identifies 0.05mrad minimum beam divergence and 1.8° maximum beam divergence under adjustable-focus conditions. These figures, spot diameter and visible-distance values relate to different focus positions and must not be treated as simultaneous values at one focus setting.
Where the final product needs a stable, repeatable spot rather than user adjustment, the focus can be factory-set and secured before shipment. OEM teams should define the target focus position, optical path, working distance and final-product emission requirements before confirming the configuration.
3. Mechanical, Electrical and Assembly Integration
The module uses a copper housing with a 6mm diameter, a 14.5mm overall length and a 10mm front lens barrel. Standard red and black leads extend approximately 8cm beyond the module structure and can be customized for the assembly requirement; the red lead is positive and the black lead is negative where that polarity option is used.
The standard electrical specification is a 3V supply with a 30mA maximum input-current rating. The specified operating-temperature range is -10 to +45°C. Mechanical retention, lead routing, electrical protection, thermal conditions and optical alignment must be evaluated in the OEM's finished product.
The module can produce an adjustable output spot diameter of up to 30mm. Final spot diameter depends on the focus position and the actual system geometry, so it should be confirmed in the intended mechanical and optical assembly.
4. OEM Integration Directions for Toys, Interactive Products and Compact Devices
For smart toys, RC models, interactive products and compact display devices, the product-selection question is not simply whether a 650nm red laser is available. OEM teams need to define the intended projection function, working distance, desired spot appearance, permitted enclosure geometry, user-access conditions and factory-set or adjustable-focus requirement.
The 650nm 5mW adjustable-focus EEL laser module is intended for component-level integration into such products. It provides a compact red-dot source for OEM development, while final optical performance, system safety classification, accessible emission and market-compliance responsibilities remain with the finished-product manufacturer.
5. Evaluation, Documentation and Custom Development Support
During an OEM evaluation, define the final focus setting, optical path, mechanical retention, lead configuration, supply arrangement and system-level safety conditions. 1ONELASER can discuss factory-fixed focus, lead-length requirements and other integration parameters for the intended product architecture.
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. Can the 650nm 5mW EEL laser module be supplied with fixed focus?
Yes. The focus is adjustable by rotation during evaluation, and a fixed-focus configuration can be factory-set and secured before shipment. Provide the required working distance and intended spot requirement for the OEM review.
FAQ 2. Are the spot diameter and beam-divergence values simultaneous specifications?
No. The source specification states that spot diameter, beam divergence and visible distance vary with focus position. Values associated with different focus settings must not be treated as simultaneous specifications at one focus position.
FAQ 3. Can the lead length or polarity arrangement be adapted for product assembly?
The standard lead length is approximately 8cm and can be customized for assembly requirements. The standard polarity option is red positive and black negative; confirm the required lead configuration with the final product architecture.
