633 nm Red Lasers

633 nm is the classic Helium-Neon (He-Ne) laser wavelength, reproduced with solid-state diodes and DPSS sources for zero-maintenance operation, compact footprints, and long service lifetimes. Applications include interferometric dimensional metrology, optical alignment, Raman spectroscopy, holographic recording, and particle sizing.
