Cryogenic microscopy allows the examination of cellular structures in their near-to-native state. However, users face complex challenges, such as preparation, devitrification, ice contamination, loss of samples or correlation across imaging modalities. ZEISS Correlative Cryo Workflow connects widefield, laser scanning, and focused ion beam scanning electron microscopy in a seamless and easy-to-use procedure. Hardware and software are optimized for the needs of correlative cryogenic workflows, from localization of fluorescent macromolecules to high-contrast volume imaging and on-grid lamella thinning for cryo electron tomography.
- Seamless cryogenic workflow across multiple modalities
- Sample protection against devitrification and ice contamination
- High-resolution fluorescence imaging
- High-contrast volume imaging and 3D reconstruction
- Targeted on-grid lamella thinning for cryo TEM applications
- Multipurpose use for cryogenic and room temperature applications
With ZEISS Correlative Cryo Workflow, you master the challenging combination of different imaging modalities under cryo conditions. The workflow solution connects light and electron microscopy, enabling volume imaging and efficient production of TEM lamellae. Dedicated accessories simplify the workflow and facilitate a safe transfer of cryo samples between the microscopes. Data management is assured by ZEN Connect, which keeps your data in context throughout the workflow. A series of processing tools help you enhance the imaging results.
Thanks to cryo-compatible objectives and the high sensitivity of the Airyscan detector, ZEISS LSM systems enable you to detect proteins and cellular structures at high resolution while gentle illumination and constant low temperatures prevent your samples from devitrification. The ZEISS Crossbeam FIB-SEM lets you enjoy high-contrast volumetric imaging – even without heavy metal staining applied to your samples. Both modalities provide valuable functional and structural information that can give you a thorough understanding of ultrastructure, whether or not you follow up with TEM studies.
Unlike other solutions, the ZEISS microscopes involved in the workflow can be used not only for cryogenic microscopy, but also for room temperature applications, which is particularly advantageous when the microscopes are not being fully utilized for cryogenic experiments. Converting the instruments from cryogenic to room temperature usage is done quickly and doesn’t require technical expertise. This flexibility gives users more time for their experiments. Imaging facilities benefit from better utilization and a faster return on investment.
SEM Electron Optics
The FE-SEM column of ZEISS Crossbeams is based on Gemini electron optics as all ZEISS FE-SEMs. Decide on the Gemini VP column of Crossbeam 350 or the Gemini II column of Crossbeam 550.
Field emission SEMs are designed for high resolution imaging. Key to the performance of a field emission SEM is its electron optical column. Gemini technology comes with all ZEISS FE-SEMs and FIB-SEMs: it is tailored for excellent resolution on any sample, especially at low accelerating voltages, for complete and efficient detection, and ease-of-use.
Gemini Optics is Characterized by Three Main Components
- The Gemini objective lens design combines electrostatic and magnetic fields to maximize optical performance while reducing field influences at the sample to a minimum. This enables excellent imaging, even on challenging samples such as magnetic materials.
- Gemini beam booster technology, an integrated beam deceleration, guarantees small probe sizes and high signal-to-noise ratios.
- The Gemini Inlens detection concept ensures efficient signal detection by detecting secondary (SE) and backscattered (BSE) electrons in parallel minimizing time-to-image.
Benefits for Your FIB-SEM Applications
- Long-term stability of the SEM alignment and the effortless way it adjusts all system parameters such as probe current and acceleration voltage
- Achieve distortion-free, high resolution imaging even over large fields of view with the help of the near magnetic-field free optics
- Tilt the specimen without influencing the electron optical performance
- Maximum sample flexibility in multi-purpose environments
- In situ experiments with outgassing or charging samples
- Unique Gemini material contrast with the Inlens EsB detector
- High resolution even at low voltage and high current thanks to the double condenser system
- More information in less time with high resolution imaging and fast analytics
- Unique topographical and material contrast with simultaneous Inlens SE and EsB imaging
Gemini Novel Optics
Today’s SEM applications demand high resolution imaging at low landing energy as a standard. It is essential for:
- beam sensitive samples
- non-conductive materials
- gaining true sample surface information without undesirable background signal from deeper sample layers
The novel Gemini optics are optimized for resolutions at low and very low voltages and for contrast enhancement.
Technological characteristics are the high gun resolution mode and the optional Tandem decel.
- The high gun resolution mode results in minimized chromatic aberration thanks to of a reduction of primary energy width by 30%.
Tandem decel, now introduced to ZEISS Crossbeam 350/550, can be used in two different modes:
- Tandem decel, a two-step deceleration mode, combines the beam booster technology with a high negative bias voltage that is applied to the sample: the electrons of the primary electron beam are decelerated, thus the landing energy is effectively reduced
- Apply a variable negative bias voltage between 50 V and 100 V. One application mode enhances the contrast of your images
- Apply a negative bias voltage between 1 kV and 5 kV and improve the low kV resolution of your images
The Ion-sculptor FIB column speeds up your FIB work without compromising machining precision and lets you benefit of its low voltage performance for any sample.
The ZEISS Crossbeam Family carries the next-generation focused ion beam column, Ion-sculptor, featuring high currents for high throughput and excellent low voltage performance for high sample quality.
- Maximize sample quality by using the low voltage capabilities of the Ion-sculptor FIB column
