20*90mm 405nm 80mw laser module

405nm 80MW laser module

20*90mm laser module for laboratory

405nm 80MW laboratory laser module

Professional-grade Φ20×90mm violet laser module with 405nm wavelength and 80mW output, featuring a high-quality glass collimating lens, built-in APC (Auto Power Control) constant current driver, and an externally adjustable focus mechanism.

The 405nm violet beam produces a tight, low-divergence spot with superior short-wavelength resolution—ideal for fluorescence excitation, UV curing, 3D printing (SLA/DLP), PCB exposure, machine vision, and scientific instrumentation requiring precise, stable violet light output.
