Technically, laser diffraction micrometer (hereafter ‘LDM’) is not a Next Generation instrument, as it has been applied among giant brands of Ultra Fine wire players for decades. Yet, it may be literally the N.G. solution to players who are using laser scan micrometer (hereafter ‘LSM’) in the same field.

System integration (close-loop system for measure and control) is not a part of the difference between the two technical principles (diffraction & scanning), which means both LDM and LSM can be implemented for close-loop system.

Here are THREE MAJOR REASONS the LDM is most recommended:

1. Investment in quality control is never a wrong approach. LDM accuracy is at least x10 higher than LSM, which gives more essential information for your R&D and production. i..e. LDM reads wire diameter in real-time, while LSM is giving you an average diameter.

2. Implement of LDM is pain less for long term of using.

Using LSMs as they all have rotating-mirror inside, you have to pay for routine maintenance and parts replacement to keep them working correctly. Yet, after you paid all the money, you still have no idea when the moving parts shall go fail or drift from quality standards until the problem itself occurs.

Using LDM, you don’t have any surcharges to pay, and you don’t worry about its reliability. It is all static parts inside.

3. LDM costs higher than all low scanning rate LSMs, but equal to or even lower than a high scanning rate LSM.

Will replace existing LSM to LDM halt production?

Yes, it may interrupt production a little bit for the replacement, but if you refer to reason 2 about the reliability and maintenance free features of LDM, you know such a short interruption is worthen. Actually, using LDM can eliminate all future production halts which could be raised by using LSM.
