| The M2-200s maintains our leadership position providing the only ISO compliant system for all reported measurements. The high speed optical
train uses a fixed position lens, and automatically translates the image on the camera from the near field to the far field. All measurements
and translations, as well as incremental beam attenuation, are automatically computer controlled. Manual mode is available for beams
that are too large or too small or at wavelengths outside the standard optical train. The Spiricon M2-200s Beam Propagation Analyzer is
fully ISO 11146. |
| The M2-200s optical train uses a fixed position lens and camera. The mirrors that direct the focused beam into the camera are moved to
precise locations, translating the beam through both the waist region and the far field regions. All these measurements and translations,
as well as incremental beam attenuation, are automatically controlled by the M2-200s software. Software improvements in the M2-200s,
including more efficient algorithm execution, has decreased the measurement reporting time by 2-3 times, making it possible to report M2
in under two minutes. |
| Spiricon products are known for accuracy. Using our patented UltracalTM calibration method and auto apeturing, to exclude noise beyond
the wings of the laser beam, you are assured of the most accurate measurements in the industry. |
| Spiricon has redesigned the M2-200, the world's top selling beam propagation system to include customer input, increased attention to
durability, and operational robustness for continuous use applications; three shifts a day, seven days a week. Novice and seasoned users
will appreciate these new features along with the time-tested excellence that the Spiricon M2-200 measurement system has provided over
the years. |

This window displays quantitative measurements
of the laser parameters. These include the X and Y beam widths, M2 or K,
the divergence angles, the Rayleigh range, and other parameters shown.
The 2D or 3D beam profile
of the currently measured
point in the beam
propagation curve. This
image enables visual intuitive
verification of the
beam profile behavior
through focus. After each
run the user can click
any individual measured
point and observe the
beam profile. Outlying or
anomalous points can be
automatically or manually
excluded from the curve
fit calculations for more
accurate results.
|  |
This window presents measurements of beam
width vs. position for a given run. After measuring a few points, the software
extrapolates a curve fit. The Xs and Ys represent individual measurement
points. The solid lines present the best fit hyperbola of the beam propagation
equation to the measured points. The M2 and other laser parameters are computed
from the best fit hyperbola since it provides a smoothing of the data points. |

 |
| Not all commercial M2 measuring instruments conform to the ISO 11146 method of employing a fixed position lens and moving detector.
Instead, some manufacturers use a fixed position detector and a moving lens. If the laser beam is diverging or converging within the travel
range of a moving lens, the reported M2 value and other results can be significantly compromised. The Spiricon M2-200 Beam Propagation
Analyzer is fully ISO 11146 compliant. |
| |
| The automatic version of the M2-200 system includes
an optical train with a fixed position lens. The optical
train automatically translates the camera through
the waist region and the far field regions. Mounted
steering mirrors direct the focused beam onto the
camera. The table is connected to a very precise
lead screw and stepper motor to translate the table in
known increments. This generates a series of beam
width measurements along the path of the focused
beam. All of these measurements and translations,
as well as incremental beam attenuation, are
automatically controlled by the M2-200 software.
A high speed USB interface allows use with laptop
computers. |
 |
| |
| The M2-200 can be purchased without the optical train. Manual measurements may be taken from beams that are too large or too small or at
wavelengths incompatible with the optics and camera contained in the optical train. UV and IR lasers from 157 to 248nm and 1µm to 1000µm
can be measured manually with a Pyrocam III camera (see description below). The user manually positions the camera on a rail, adjusts the
attenuation to match the camera's dynamic range, and captures each frame individually, with each step prompted by the M2-200 software. |

Different lenses are needed for different wavelength regions. One lens is included with the M2-200 systems. Additional lenses must be ordered
separately. The M2-200s model include 3 standard lenses with nominal 300mm focal lengths. See below. |

| 1 CCD cameras can be damaged by power in excess of 100 mW/cm2 or energy in excess of 100 mJ/cm2. The M2-200/200s employs a focusing optic. While
it may be that the laser input power or energy measures well below this damage threshold, it can easily exceed these levels when focused onto the
camera sensor. Use caution and error on the side of safety. CCD cameras can be costly to repair or replace. |
