Adjustable Brightness 450nm 500mW Blue Line Laser Module with Powell Lens

Industrial high-precision detection, machine vision positioning, and precision manufacturing scenarios, featuring a Powell lens exclusive uniform line laser design, 450nm high-contrast visible blue light, 500mW stable power output, and high-precision stepless adjustable brightness. Optimized for the core demands of industrial high-precision applications—ultra-uniform line laser, high straightness, adjustable light intensity for complex environments, and long-term stable operation—it abandons the Gaussian distribution defect of traditional cylindrical lenses, outputs a completely uniform blue line laser with no "bright center and dark edge", and realizes stepless brightness adjustment via professional modulation technology. With its industrial-grade high-precision optical system, intelligent constant current drive, and rugged structural design, it is the ideal optical solution for 3D machine vision inspection, precision industrial alignment, flat panel display detection, automated assembly positioning, and laser processing auxiliary guidance, effectively improving the accuracy and efficiency of industrial high-precision operations.

Basic Core Characteristics

• 450nm Blue Light & 500mW Stable Power: 450nm high-brightness visible blue light with ultra-high visual contrast (far higher than red light) on metal, non-metal, glass, and PCB substrates; 500mW moderate high power output (Class IIIa laser safety standard) meets the energy demand of industrial high-precision line laser applications, no harm to human eyes and equipment, and no overexposure or glare in close-range operation.

• Powell Lens Core Advantage - Absolute Uniform Line Laser: Adopts imported high-precision Powell lens (prism line generator) optimized for 450nm blue light, abandons the Gaussian distribution defect of traditional cylindrical lenses, outputs a 80% energy-uniform blue line laser with no bright center, dark edge or hot spot; the line laser energy uniformity rate reaches ≥80%, eliminating detection blind spots and positioning errors caused by uneven light intensity.

• High-Precision Stepless Adjustable Brightness: Supports PWM/TTL dual-mode stepless dimming (0-100%) with high precision brightness adjustment resolution (±1%); the light intensity can be flexibly adjusted according to different working environments (strong ambient light/ darkroom) and detected object characteristics (high reflectivity/low reflectivity), realizing adaptive optical output for complex industrial scenarios.

• Industrial-Grade High-Precision Optical System: Equipped with imported anti-reflection AR coating optical lens group (450nm optimized), high-precision laser collimation and shaping design;  and no line distortion or deflection at long working distances (0.1-5m), meeting the micron-level positioning and detection requirements of industrial high-precision applications.

• Rugged Industrial Structural Design: Anodized 6063 aluminum alloy integrated shell with high-precision CNC machining, excellent electromagnetic interference (EMI) resistance and anti-vibration performance (resistant to 5G vibration); integrated efficient passive heat dissipation structure, solving the thermal accumulation problem of 500mW power output.
