Features
BeamSquared M² Propagation Analyzer
Introducing the BeamSquared, a compact and fully automated tool for measuring the propagation characteristics of continuous wave and pulsed laser systems from the UV to NIR to Telecom wavelengths.
BeamSquared Automated ISO Set-Up
This video describes the BeamSquared software Auto ISO measurement feature, which makes obtaining an ISO compliant beam measurement as easy as "align and click."
Automatic M² - at Production Speeds
The BeamSquared optical train uses a fixed position lens with movable mirrors and camera. The mirrors that direct the focused beam into the camera are moved to precise locations, translating the beam through the near field, the waist, and the far field regions. All these measurements and translations, as well as incremental beam attenuation, are automatically controlled by the BeamSquared software. Design improvements in the BeamSquared system have decreased the measurement reporting time by 2-3 times, making it possible to report M² in under a minute.
Manual M²
Manual mode is available for wavelengths greater than NIR, particularly Terahertz and above, and for beams that are too large or too small for the BeamSquared optical system. Users are required to provide a manual translation/attenuation apparatus.
2D Measurements
BeamSquared measures propagation characteristics in both the X and Y axes and displays the following parameters:
Wֺֺaist diameters
Fֺֺull angle Divergences
Wֺֺaist locations
Rֺֺayleigh lengths
Mֺֺ2 or K and BPP factors
Aֺֺstigmatism
Aֺֺsymmetry
To optimize bench space, BeamSquared can be mounted either horizontally or vertically. Laser beam input port is the same dimension with either mounting method, X = Y, and the same as the M2 -200s that it is replacing.
Because of the design of the lenses for the new BeamSquared, you will be able to use lenses on multiple systems. We have included an RFID chip on each lens which holds the information for that lens. We have also programmed the BeamSquared optical trains to have their calibration information stored in the device. With this improvement the configuration files for pairing optical trains and lenses are no longer required making lenses interchangable.
The BeamSquared SP204S-PRO is compatible with any lens set; however, its highest accuracy is achieved when using the specially calibrated lenses included with the device.
M² measurement is important if the stability of your laser is important to your process. Taking M² measurements on a frequent basis allows you to see if your laser is stable from time to time. If the results of the M² measurement fluctuate and a noticeable change happens over time, this could help identify problems with consistency in the laser and help prevent negative results to your process where the laser is being utilized.
Before allowing laser energy to enter the instrument, it is important to limit the beam intensity. Excessive laser energy may cause damage to the camera or the internal components of the BeamSquared optical train.
Typically, a CCD camera sensor can be damaged at energy levels in excess of 1 mJ/cm² or at power levels greater than .15 mW/cm². Adjust these input limits downward based on the likely focused spot size resulting from your M² lens focal length. Beam splitters and/or filters may be used to attenuate the beam, but care must be used to prevent the introduction of distortions.
During an M² measurement operation, the peak energy density that reaches the camera will change, potentially over several orders of magnitude. This is a result of the camera effectively moving from a larger unfocused spot near the lens, into and through the focus at the waist, and then out again to an unfocused spot (see the Adjusting Brightness section in the manual). The Linear attenuators in the optical train will automatically adjust to accommodate these changes in beam intensity, so long as the operator, has prudently selected the initial beam intensity. Thus, it is the operator's responsibility to attenuate the laser sufficiently to operate within the safe dynamic range of the BeamSquared system.
BeamGage systems and BeamSquared systems are separate and the cameras with them are not always interchangeable. However, if you currently have an SP204S, SP920, XC-130, SP1203 or one of our Pyrocam IIIHR or IV cameras, you can upgrade these cameras to be compatible with the BeamSquared software (Note: Pyrocams are not compatible with the optical train).
The two software programs and their motion controller drivers cannot be installed concurrently. The M2-200s software only supports up to Windows 7 operating systems and uses older motion controller drivers where the BeamSquared software supports up to Windows 10 and uses updated motion controller drivers that are not compatible with the M2-200s system.
To operate them from the same computer requires that the computer be a Windows 7 operating system and that you uninstall the previous program including the motion controller drivers first, then reboot the computer before you can install the other software with its motion controller drivers.
M2-200S is an End-of-Life product , service, recalibration and recertification of this product is also discontinued because of discontinued usage of Windows 7 systems by MKS.
The BeamSquared SP204S-PRO system can work with any SP204S camera or other supported cameras (SP204S, SP920, XC-130, SP1203) that have a BeamSquared Software license. However, for the best performance and highest accuracy, the original SP204S camera and lenses shipped with the system are recommended.
The BeamSquared SP204S-PRO system undergoes special calibration with its cameras and lenses during production. The system registers the serial numbers of the camera and lens to ensure compatibility. When the correct camera and lens set is recognized, the BeamSquared-PRO software activates its advanced calculation capabilities.
The BeamSquared SP204S-PRO is specifically engineered for exceptional accuracy in UV wavelengths, large Rayleigh lengths, and larger beam diameters. This is achieved through its specialized quality optics, advanced lens calibration, and algorithm enhancements.
In addition to measuring M², waist location, divergence, and other laser parameters, the BeamSquared SP204S-PRO also ensures superior accuracy in astigmatism calculations, setting it apart from the Beamsquared SP204S.
