The N-STP-910 Frequency/Intensity Stabilized Red Helium-Neon (HeNe) Laser Description：

N-STP-910 manual N-STP-910 Resources

The N-STP-910 Frequency/Intensity Stabilized Red Helium-Neon (HeNe) Laser employs highly refined thermal compensation technology to achieve an excellent balance between output power and stability, low-temperature sensitivity, and reliability. It features user-adjustable output power (typical range: 0.35 to 0.70 mW) or frequency (blue side: 400 to 600 MHz). Within 8 hours, it maintains intensity stability of < ±0.1% (1 hour) and frequency stability of ±1 MHz, with a lock time of < 10 minutes. The mirror quality and performance are optimized to deliver the highest-quality HeNe laser available on the market. This high-performance laser comes with a one-year warranty. Proprietary design and manufacturing techniques ensure a highly stable and quiet signal, unaffected by environmental temperature drift, along with a clean, stable, and reliable output power of at least 0.5 mW. The N-STP-910 frequency stability specifications include defined frequency ranges for each time interval and temperature interval. The short-term frequency stability of the N-STP-910 model makes it an excellent choice for unequal-arm interferometers. It ensures intensity stability for surface texture characterization, velocity measurement, scattering, and polarization. The intensity lock guarantees highly stable output power (less than 0.1% over short intervals), making it ideal for applications where optical signal intensity varies with the test object. Examples include surface scattering, profilometry, and single-axis velocimetry. The laser is CE compliant and meets IEC Class 2 standards. A power supply is included.

Function：

Frequency-stabilized mode

Ensures frequency stability for long-path difference interferometry, metrology, holography, spectroscopy, and frequency marking. The short-term frequency stability of the laser makes it an ideal choice for unequal-arm interferometers. With a coherence length on the order of 100 meters, helium-neon (HeNe) lasers are perfect for applications requiring large depth of focus in holography and metrology. Frequency stability further enhances coherence length for critical measurements or exposures.

Intensity-stabilized mode

Ensures intensity stability for surface texture characterization, velocity measurement, scattering, and polarization. The simple single-button intensity lock guarantees highly stable output power (less than 0.1% over short intervals), making it ideal for applications where optical signal intensity varies with the test object, such as surface scattering, profilometry, and uniaxial velocity measurement.

Optimized endoscopic performance:

With an enhanced design and superior optical components, the laser delivers unparalleled operational stability and service life. Mirror quality and performance have been optimized to provide the highest-quality helium-neon lasers on the market. This high-performance laser comes with a one-year warranty.

Advantages of Helium-Neon Lasers:

Helium-neon lasers use a helium-neon gas mixture as the gain medium excited by electrical discharge. Based on mature mainstream technology, helium-neon gas lasers provide a highly cost-effective, easy-to-use laser source with fundamental Gaussian beam quality. They offer stable light output unaffected by optical feedback over a lifespan exceeding 20,000 hours.

Helium-Neon Laser Mount:

The ULM Series cylindrical laser mount connects to the 340-RC and 370-RC rod clamps, providing a convenient way to attach these helium-neon lasers to Newport platforms, workbenches, or breadboards.
