Get low signal capacitances and leakage currents with PNDetector’s Standard BSD
Our BSDs with different chip geometries and active areas ranging from 40 mm² to 150 mm² are the best choice for applications with fixed position setups below the pole piece of the SEM.
Key Features
-
Very low dark currents below 1 nA
-
Very low signal capacitance down to 3 pF
-
Non-magnetic materials and low outgassing
-
Optimized detector geometry for your application
-
To be combined with our Standalone 4-Channel Preamplifier as a whole detector module. This preamplifier with the compact size of 33 mm x 29 mm x 5.5 mm is suitable for applications with restricted space around the BSD diode. It is equipped with two flex lead cables to be connected to our Standard BSD from one side and to the Main Amplifier from the other side
