Für dynamische Disziplinen zählt jede Zehntelsekunde – und jedes Gramm. Das MPS-C wurde genau dafür entwickelt: Ein ultrakompaktes, geschlossenes Leuchtpunktvisier, speziell optimiert für moderne Sportpistolen und den präzisen Schuss unter Zeitdruck. Basierend auf der bewährten MPS-Plattform, liefert das MPS-C alles, was Leistungs- orientierte Schützen brauchen.Einen klaren, schnell erfassbaren Leuchtpunkt, ein robustes, abgedichtetes Gehäuse und eine extrem geringe Bauhöhe – perfekt für beidäugiges Zielen und schnelle Zielwechsel. Mit nur 32 g ist es bis zu 40 % leichter als vergleichbare Systeme und damit ideal für jede Pistolenplattform, auf der es auf Geschwindigkeit, Balance und Kontrolle ankommt.

All SEM sample surfaces are typically coated with a thin hydrocarbon contamination due to sample preparation or storage. This contamination can affect and inhibit good resolution of the sample surface, especially in a FE-SEM. The UV Prep for SEM is the optimal system for the removal of this thin hydrocarbon film without affecting the sample itself. When stored in an open environment, samples pick up contamination through the air. Unless they are handled carefully, they will also pick up contamination through handling. The UV Prep for SEM is designed to mitigate or eliminate these effects. Why is it so important to remove this contamination prior to examination? Typical FE-SEM users are running at lower and lower beam energies. The lower the beam energy, the more sample surface detail is imaged. That same sample surface that has contaminants on it. If not removed, the user is actually imaging the contaminants, and not the true sample surface. Many times, when focusing at high magnification in order to perform analysis or capture images at lower magnification, a "black box" can be formed on the sample. In many cases, this is caused by raster burn or electron beam induced deposition (EBID) not of the sample, but of the hydrocarbon contaminants on the sample surface. Removing these hydrocarbons from the surface prior to analysis with the UV Prep for SEM can greatly reduce the appearance of this black box effect. Many users purchase new FE-SEMs in order to take advantage of their unique operating abilities (high resolution imaging at very low kV). What they don not realize is that the only way to obtain the advertised resolution of the microscope is to start with a clean sample. Even the best microscopes in the world will give poor images of dirty samples! Look through our gallery to see how the UV Prep for SEM really can enhance the image quality of a variety of materials under many conditions.
