Ultra-Low Noise (ULN) and Visible Laser Modules (VLM)
OEM laser modules offering ultra-low noise or extreme miniaturization, with circular, elliptical, or fan line output for use in inspection, alignment, and instrumentation.
The tiny VLM style modules are fully featured robust systems. The head includes precision aligned, high-quality glass optics, plus a photodiode and feedback electronics to control the power. The ULN modules eliminate mode-hops and deliver <0.06 % output noise.
VLM and Ultra-Low Noise Modules
Get a high-performance red laser beam or line projection from a small economical VLM package. Or choose an ultra-low noise (ULN) module that includes its own power supply.
