Cylindrical Laser Mount assembly with Rod and Rod ClampOperates in either stable-frequency or stable-intensity mode
Long term (8 hr) frequency drift 3 MHz maximum
Typical intensity stability better than 0.2% absolute (1 hour)
Superior output power (>1.5 mW version available) from single line, linearly polarized output
Long coherence length
CE Compliant
The 633 nm Frequency/Intensity Stabilized Helium-Neon (HeNe) Laser uses a highly refined thermal compensation technique to provide an excellent balance of high output power and stability, low temperature sensitivity, and reliability. An extremely versatile research and instrumentation tool, it can toggle instantly via front panel control between intensity and frequency stable modes. In intensity stabilized mode, the HeNe laser will operate as an output power reference, with the stability of < ±0.2% (1 hour), while in the frequency stabilized mode, frequency stability as low as < ±3 MHz can be obtained over an 8 hour period. Utilizing enhanced designs and superior optical components, the laser delivers unsurpassed operational stability and lifetimes. The mirror quality and performances are optimized to result in the highest quality HeNe lasers available in the market. This high-performance laser is supported by a one-year warranty.

A Proprietary design and manufacturing technology deliver a highly stabilized and quiet signal, immunity to ambient temperature drift and upto >1.5 mW of clean, stable and reliable output power. Designed for many applications where the temperature environment cannot be rigorously controlled, the frequency stability specifications include both a specified frequency range per time interval and per temperature interval. With superb temperature sensitivity, Newport’s Intensity-Frequency Stabilized Helium Neon (HeNe) laser achieves reliable stability over the widest range of conditions.
Frequency stability for long path difference interferometry, metrology, holography, spectroscopy and frequency marking. The short-term frequency stability of the laser makes it an excellent choice for interferometers with unequal arms. With the coherence length on the order of 100 m, the helium neon (HeNe) laser is ideal for large depth-of-field applications in holography and metrology. Frequency stability further enhances coherence length for critical measurements or exposures.
Intensity stability for surface texture characterization, velocimetry, scattering and polarization. The simple, one-button intensity lock ensures highly stable (less than 0.1% over short intervals) output power, ideal for applications where optical signal strength varies with changes in the test subject. Examples include surface scattering, profilometry, and single axis velocimetry.
