LCM-S-111-20-NP25

Quick Overview

532nm 20mW CW Laboratory Style Laser
Application fields: Raman spectroscopy, laser microscopy (LSCM, MPLSM), interference measurements, spectral analysis, flow cytometry, holography, laser-assisted measurements. Features: Single longitudinal mode Ultra-low optical noise Narrow line width High coherence length Perfect beam quality, TEMoo Stable output power in wide operating temperature range High reliability RoHS compliance Very suitable for OEM projects >10,000 hours lifetime Modification LCM-S-111-20-R has been specially developed for Raman spectroscopy. Due to a special technical solution, back reflection hitting output laser aperture does not have an essential influence on the output power stability and the level of optical noise. This advantage makes the laser an ideal source for use in Raman spectroscopy.
