Adjustable UV 380nm 60mW Dot Diode Laser Module 

The Adjustable UV 380nm 60mW Dot Diode Laser Module—a compact, precision-tunable light source optimized for lab research, small-scale industrial inspection, and fluorescence excitation applications. Featuring variable spot size control and stable 380nm UV-A output, this module delivers flexible, targeted UV energy for scenarios requiring customizable light intensity and spot precision.

Core Advantages (Tunability-Focused)

Spot Size Control

Adjustable dot spot: Focusable spot size ranging via a built-in precision focusing ring; no extra optics required for spot tuning, simplifying on-site operation.

Stable wavelength performance: 380nm (±5nm tolerance) UV-A wavelength aligns with absorption peaks of fluorescent dyes, photochromic materials, and thin-film coatings, ensuring consistent experimental results.

Compact Design & Easy Integration

Miniaturized anodized aluminum housing (dimensions: 16×68mm), enabling seamless integration into microscopes, handheld detectors, or lab test benches.

Low-voltage DC input (5V) and ultra-low power consumption, compatible with battery-powered systems for field testing.

Versatile UV-A Wavelength Applications380nm UV-A wavelength avoids the strong phototoxicity of shorter UV-B/C wavelengths, making it suitable for biological sample fluorescence excitation (e.g., DNA staining, protein labeling).

Superior surface interaction with polymers, glass, and thin films for micro-defect detection and surface modification research.

Key Applications

• Lab Research & Academia: Fluorescence microscopy excitation (e.g., DAPI analog dyes), photochromic material testing, and UV-induced surface modification studies.
• Small-Scale Industrial Inspection: Micro-defect detection on glass, polymer films, and electronic component coatings; PCB solder mask quality verification.
• Biomedical & Environmental Testing: Portable water quality fluorescence detection, skin lesion UV imaging, and microbial culture observation.
• Consumer Electronics: UV curing for small-batch 3D printed resin parts, and optical sensor calibration.
