Material Matters

Huvitz objective range This particular feature is very important when considering which microscope objective to use in the application of viewing samples using a microscope. A high NA value allows the microscope user to focus on the finer details that would not be possible with an inferior optical system (low NA). Using a low NA system - fine details would not be resolved under a microscope. But with the resolving power of high NA objectives it separates the features and allows the user to view more detail of the structure. This is an important consideration when viewing the laminar structure of cementite. An objective with a high numerical aperture (NA) with good resolution to offer improved clarity to reveal the nature of the structure. Whereas an objective with a lower NA will not allow the user to view the detail of the micro structure under the microscope. The 100x objective has a NA of 0.9 and a working distance of 1mm and can resolve feature of 0.37 micron Contact us;

Spectrographic recently supplied a hardness tester to Inlex Locking, this particular company specialize in fasteners. The hardness tester will be used in the quality control laboratory and will be used for the quality inspection of fasteners . When deciding on a new system,  the major customer requirement was to improve the facilities of hardness tester measurement and we propoeed the HM Indent system which offers computer based vickers and knoop measurements.  The introduction of software for micro vickers testing improves the precision of D1 and D2 measurement.  we like the ease of use and reporting function offering output and saving of test results If you would like to find out more about the system that was installed please contact us using the details below.
