JSM-IT800 Field Emission Scanning Electron Microscope

The JSM-IT800 employs a new easy to use GUI "SEM Center", that serves as a common platform that enables a full range of functionality from high resolution observation to high speed elemental mapping. This platform features a JEOL In-Lens Schottky Plus Field Emission Electron Gun, a next-generation electron optical control system "Neo Engine" and a fully embedded JEOL EDS system. Moreover, the system can satisfy various needs of users by utilizing an innovative hybrid design of SEM objective lens.

The JSM-IT800 has two versions based on the objective lens type: Hybrid Lens version (HL version) as general-purpose FE-SEM and Super Hybrid Lens version (SHL version) for observation and analysis at ultra low accelerating voltage and at highest resolution. A new UHD (Upper Hybrid Detector) is a standard detector for SHL version, and makes it possible to obtain image with significantly enhanced S/N allowing easy observation with high image fidelity.

In addition, new backscattered electron detectors, Scintillator Bacskattered Electron Detector (SBED) and Versatile Backscattered Electron Detector (VBED) can be incorporated.
SBED enables acquisition of material contrast image with excellent sensitivity at low accelerating voltage, while VBED can help to obtain images of 3D, topography and material contrasts by employing multiple detector segments.

In-Lens Schottky Plus Field Emission Election Gun (FEG)

The integrated In-Lens Schottky Plus and low aberration condenser lens achieves high beam brightness. Ample probe current (100nA@5kV) is available even at low accelerating voltage. This allows the user to perform high resolution observation, high speed elemental mapping, EBSD analysis and Soft X-ray analysis with minimal adjustment of SEM parameters.

SEM Center・EDS integration

Full integration of microscope GUI "SEM Center" and JEOL EDS has brought about the next generation of SEM utilization. Moreover, the JSM-IT800 incorporates Smile Navi (optional) that can assist a beginner with how to operate an SEM, LIVE-AI (artificial intelligence) filter Live-AI (Live Image Visual Enhancer-AI:LIVE-AI)(optional) providing easy viewing of live image, and SMILE VIEW™ Lab for fast report generation.

SEM center・EDSインテグレーション




SMILENAVI is an assistant tool designed for beginners to allow smooth basic SEM operations. When the operator clicks on the appropriate button as indicated by the SMILENAVI flowchart, the SEM GUI is linked to the click operation for operator guidance. Since the GUI displays operation steps and button locations, operators will be able to operate the SEM without using SMILENAVI.


LIVE-AI filter (Live Image Visual Enhancer-AI:LIVE-AI)

Utilizing the AI (artificial intelligence) capability, LIVE-AI filter is incorporated for a higher quality of live images. Unlike image integration processing, this new filter can display a seamless moving live image with no residual image. This unique feature is very effective for quickly searching observation areas, focusing, and stigmator adjustment.

Hybrid Lens version (HL;Hybrid Lens) /
Super Hybrid Lens version (SHL;Super Hybrid Lens)

JSM-IT800 series objective lens design combines magnetic-lens and electrostatic-lens (Hybrid Lens Design). Thus, observation and analysis of various samples is possible from magnetic sample to insulation sample with high spatial resolution.

UHD;Upper Hybrid Detector

UHD, a new detector incorporated in SHL version objective lens is highly efficient in detection electrons arising from the specimen, enabling acquisition of images with enhanced S/N ratio.

New Backscattered Electron Detectors

Scintillator backscattered electron detector (SBED) has excellent sensitivity and is useful in obtaining material contrast image at low acceleration voltage. Versatile backscattered electron detector (VBED) enables acquisition of characteristic images such as 3D and surface topography based on divided detection element shape.

SBED (Scintillator backscattered electron detector)

Use of scintillator for detector has improved detection sensitivity and responsiveness compared to semiconductor element.

VBED Images (Versatile Backscattered Electron Detector)

Semiconductor detection element is divided into 5 segments, making it possible to select the signal suitable for the observation purpose.

Angle selection

Depending on the acquisition angle of backscattered electrons, the composition information is enhanced by the inner segment, while the topography information is enhanced by the outer segments. Moreover, comparing the contrast of fluorescent body beneath the AI deposition film, the different depth related information can be potentially investigated.
