Nanounity Introduces the Pemtron Range of Compact Scanning Electron Microscopes
Date:6/18/2013

Santa Clara, CA (PRWEB) June 18, 2013

Tabletop SEMs are inexpensive and easy to use compared to standard size SEMs but have limited performance and capability such as small sample sizes, lower magnifications and lower resolution. Full size SEMs would normally provide better imaging performance and more analytical capability but generally require more knowledge to operate and have a higher cost of maintenance. The Pemtron PS-230 and PS-250 SEMs address the gap between these two types of SEM product, offering competitive prices compared with higher end tabletop SEMs, are easy to use and have a low cost of maintenance while equalling or exceeding the performance of a full size SEM.

In choosing to offer Pemtron’s products, Nanounity studied the market-place for SEMs. Describing what was found, Nanounity director, Brad Rangell, said “We ran across many people who were evaluating or have recently purchased tabletop SEMs. Our observations suggest that many users have applications that require performance beyond a tabletop system. In many cases, the determining factor to buy a tabletop SEM is price. The user might have higher performance needs but, with a limited budget, is forced into selecting a system with added capabilities and options.”

Continuing, Rangell noted “At the other end of the scale, the full size tungsten SEMs may accept a variety of sample sizes and offer higher magnification and resolution. These systems usually offer a number of options such as motorized stages, low vacuum, sample airlocks and ports for external analytical devices. These options raise the purchase price and make the system out of reach to buyers with limited budgets. Full size SEMs are generally larger, take up more floor space, have special facilities requires and use
