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 interchangeable.

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.

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).

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.

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.
