650nm Red Dot Laser Diode Module 10–250mW Adjustable Focus 16×68mm

Elubor 650nm Adjustable Focus Red Dot Laser Diode Module

Precision meets versatility with the Elubor 650nm Red Laser Diode Module (Model: 650M-1668). Whether you're building industrial alignment systems, stage lighting rigs, or custom laser projects, this compact yet powerful module delivers a sharp, focused red dot beam across multiple power settings — from a subtle 10mW all the way up to a robust 250mW output.

Key Features

• Adjustable Focus: Twist the focus ring to sharpen or widen the beam spot for your exact application needs.
• Lock Ring Included: Securely lock the module in position once your desired focus is achieved — no drift, no slippage.
• Multiple Power Options: Available in 10mW, 50mW, 100mW, 150mW, 200mW, and 250mW configurations to suit low-power positioning tasks or high-visibility applications.
• Dual Wavelength: Operates at 648nm–650nm for a vivid, true-red visible beam output.
• Aviation-Grade Aluminum Shell: Durable, heat-dissipating housing keeps the module cool and protected during extended operation.
• Premium Optical Components: Features an imported laser diode, K9 glass lens, and a constant-current driver board for stable, consistent beam quality.
• Flexible Spot Modes: Compatible with Dot, Line, or Cross output patterns (lens configuration dependent).
• Plug-and-Play DC Power: Runs on DC 5V with a working current range of 10–280mA. Includes a 1.2m DC cable for easy integration.

Frequently Asked Questions

Q: What power output should I choose for my red laser diode module application?

A: For basic alignment and positioning tasks indoors, 10mW or 50mW is typically sufficient and offers lower visibility risk. For stage lighting, outdoor use, or longer working distances, 100mW–250mW provides a brighter, more visible red dot beam. Always match the power level to your specific environment and safety requirements.

Q: Can I adjust the focus of this 650nm laser module?

A: Yes! The module features an adjustable focus mechanism that allows you to tune the beam from a tight, sharp dot to a broader spot. Once you've dialed in the perfect focus, simply use the included lock ring to secure the position and prevent any accidental movement.

Q: What power supply does this laser diode module require?

A: The module operates on DC 5V with a working current range of 10–280mA depending on the power variant selected. It includes a 1.2m DC cable for easy connection to your power source. An external DC 5V power supply (not included) is required for operation.

Q: Is this red laser module suitable for stage lighting or professional DJ setups?

A: Yes — this module is designed for professional stage and DJ applications, as well as industrial alignment, machine vision, and DIY laser projects. Its compact 16×68mm aviation-grade aluminum housing makes it easy to mount and integrate into custom builds or existing stage rigs.
