The N-STP-912 Frequency/Intensity Stabilized Red Helium-Neon (HeNe) Laser Description：

N-STP-912 manual N-STP-912 Resources

The N-STP-912 Frequency/Intensity Stabilized Red Helium-Neon (HeNe) Laser employs highly refined thermal compensation techniques to achieve an excellent balance between output power and stability, low-temperature sensitivity, and reliability. It features user-adjustable output power (typical: 0.60 to 1.40 mW) or frequency (blue side: 50 to 600 MHz). Within 8 hours, it maintains intensity stability of < ±0.1% (1 hour) and frequency stability of ±1 MHz, with a locking time of < 10 minutes. The mirror quality and performance are optimized to deliver the highest quality HeNe laser on the market. This high-performance laser comes with a one-year warranty. Proprietary design and manufacturing techniques provide a highly stable and quiet signal, unaffected by environmental temperature drift, and deliver a clean, stable, and reliable output power of 1.0 mW (minimum). The N-STP-912 frequency stability specifications include defined frequency ranges per time interval and temperature interval. The short-term frequency stability of the N-STP-912 model makes it an excellent choice for unequal-arm interferometers. It ensures intensity stability for surface texture characterization, velocity measurement, scattering, and polarization. Intensity locking guarantees highly stable (less than 0.1% over short intervals) output power, ideal for applications where optical signal intensity varies with the test object. Examples include surface scattering, profile measurement, and single-axis velocimetry. CE compliant, IEC Class 3R. Includes power supply.

Function：

Frequency-stabilized mode

Ensures frequency stability for long-path differential interferometry, metrology, holography, spectroscopy, and frequency marking. The short-term frequency stability of the laser makes it ideal for unequal-arm interferometers. With a coherence length on the order of 100 meters, the Helium-Neon (HeNe) laser is perfectly suited for applications requiring large depth of focus in holography and metrology. The frequency stability further enhances the coherence length for critical measurements or exposures.

Intensity Stabilization Mode

Ensures intensity stability for surface texture characterization, velocity measurements, scattering, and polarization. A simple single-button intensity lock maintains highly stable output power (less than 0.1% over short intervals), making it ideal for applications where light signal intensity varies with the test object. Examples include surface scattering, profilometry, and uniaxial velocity measurements.

Optimized laparoscopic performance:

With an enhanced design and superior optical components, the laser offers unparalleled operational stability and service life. Mirror quality and performance have been optimized to deliver the highest-quality HeNe lasers in 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 a mature mainstream technology, helium-neon gas lasers offer a highly cost-effective solution that achieves fundamental Gaussian beam quality with user-friendly operation. These lasers provide stable optical output for over 20,000 hours of service life, with minimal susceptibility to optical feedback interference.

Helium-Neon Laser Mount:

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