Faraday Cup


A Faraday Cup is used for measuring the beam current at the specimen plane. The beam of electrons is focused inside the hole by increasing magnification so that when the hole fills the screen all the electrons are trapped and a true measure of current is achieved. The hole size of the Faraday Cup is 150µm. The Faraday Cup can be added to a block of standards or can be supplied as a single; as a single it can be set in any size block required.


Carousel Configuration


These blocks offer the user the opportunity to extend the current block of standards by adding one or more standards to their existing set of standards. The carousel is able to nestle around the outside of the users original block. These blocks are custom made and therefore the original block dimensions are required. The number of standards which can be embedded in this type of standard is dependent on the dimensions required.


Specially Manufactured Block


If our range of mounts do not accommodate your requirements, we would be happy to work with you to provide your exact requirements. Examples are detailed below.


Available as: JL-01


Available as: JL-03 NIST Standard Sets


The following sets are only available as sets of standards. These can be ordered as an individual set of standards (as shown) or be added to a block of standards.
