OBIS lasers now with single frequency and narrow linewidth. These are direct diode laser modules with an internal Volume Holographic Grating (VHG) to create a single frequency, long coherence length laser for single longitudinal mode (SLM) applications.

OBIS LX SF at 785 nm can support demanding applications such as Raman Spectroscopy.

High signal and low noise gives your application exceptional signal-to-noise ratio (SNR).

OBIS Lasers offer superior performance and reliability.

OBIS LX Lasers are built with Direct Diode technology.

Exceptional beam quality (M² ≤ 1.5) and low noise (RMS ≤ 0.05%) provides your application with high Signal-to-Noise ratio and contrast.

Designed for the most demanding Life Science, Medical and Semiconductor Markets.

Operate in Continuous Wave (CW) mode with output power control via host computer (USB or RS-485).

Requires +12 Volts DC power. Order Power Supply separately or OBIS Remote separately.

Order OBIS Heatsink separately for easy mounting and cooling.
