SEM Peltier stage system for in-situ heating & cooling
The Deben Coolstage can also be used for high vacuum heating and cooling applications inside the SEM. The Deben Coolstage is available for all SEMs and guaranteed temperature range is +50°C to -25°C (at 300Pa chamber pressure) or less than -30°C at higher vacuums.
SEM Probe Current Meter
A low-cost 3½-digit liquid crystal display readout of Electron Beam Probe Current. The free-standing meter is battery powered and measures from below 1pA to 2μA in 5 switched ranges. The meter has automatic zero correction but there may be small residual error not exceeding 5pA at 25°C. Where absolute readings are required on low ranges this small error may be subtracted from the reading obtained.
JEOL SEM Motorised objective aperture holder
The motorised unit completely replaces the existing final aperture assembly and utilises the existing aperture strip. The system comprises a precision motorised mechanical assembly, drive electronics and keypad controller.
Deben can supply a TV chamberscope for your SEM using an internally or externally mounted high resolution camera with infra-red illumination. The chamberscope can be mounted on any available free port, even one not directly in line with the centre of the column. There is a choice of wide or narrow angle lenses which are user interchangable. Systems are available with or without monitors and with optional USB control and image display. Deben chamberscopes are available for most SEM models, contact us for a quotation and to check compatibility on your SEM.
Beam Blanking for SEMs
The Deben PCD Beam Blanker has been designed to provide JEOL and Hitachi FEG, LaB6 and tungsten SEMs with the capability of blanking, pulsing or otherwise modulating the electron beam. The blanking unit utilises the PCD port on the side of the column (opposite the final aperture) and will operate at up to 30KV with a switch on/off time of approximately 50nS. There is an integral faraday cup and probe current detector for an indication of probe current. A BNC connector is provided for connection to an optional probe current meter should a more accurate reading be required.
