Laser Diode Module (Red, 5mW) with Adjustable Focus

Overview: Precision Light for Aiming and Sensing. The Red Laser Diode Module is a critical component for projects requiring a highly focused, narrow light beam. This module integrates the laser diode, driver circuit, and focusing lens into a single, easy-to-use package. It provides a stable, highly visible red beam (typically 650nm) ideal for PRECISION AIMING, distance measurement experiments, and light curtain applications. This module is an ABSOLUTELY ESSENTIAL tool for robotics, surveying, and security projects built by engineers and students in Bangladesh.

Key Technical Features: Precision and Integration. Component Type: Laser Diode Module (Integrated driver). Color/Wavelength: RED LIGHT (Typically 650nm). Output Power: LOW POWER (Typically less than 5mW, Class 3A/3R equivalent). Operating Voltage: 3V to 5V DC (Directly compatible with Arduino/TTL logic power). Key Feature: ADJUSTABLE FOCUS (The front lens can usually be screwed in/out to adjust the dot size/focus). Interface: Simple 3-wire interface (Power, Ground, sometimes Signal/Enable). Beam Profile: Highly collimated, narrow beam for precision applications.

Applications: Aiming and Detection. This laser module is expertly suited for: Building LASER AIMING SYSTEMS on robots or camera rigs, implementing SECURITY LIGHT CURTAINS and tripwires, creating SCANNING OR DETECTION systems for industrial processes, demonstrating FIBER OPTICS principles, and use in EDUCATIONAL KITS for optical experiments.

⚠️ SAFETY WARNING AND USAGE NOTES (CRITICAL). This product contains a LASER DIODE. NEVER LOOK DIRECTLY INTO THE LASER BEAM OR POINT IT AT PEOPLE OR AIRCRAFT. Prolonged direct exposure can cause eye damage. Always wear appropriate laser safety glasses when operating. Ensure proper current limiting is used if you are driving the laser with a custom circuit.
