Q: What is a desktop SEM?

A desktop SEM (scanning electron microscope) is a compact, benchtop instrument that provides high-resolution imaging at the nanometer scale. Unlike traditional floor-model SEMs that require dedicated rooms and specialized infrastructure, desktop SEMs fit on a standard lab bench, operate on standard power, and are designed for ease of use. They deliver research-grade performance in a more accessible package.

Q: How does a desktop SEM compare to a floor-model SEM?

Desktop SEMs like the SNE-Alpha achieve 5nm resolution—comparable to many floor-model instruments. The main trade-offs are a smaller sample chamber and sometimes fewer detector options. However, desktop SEMs offer significant advantages: lower cost, smaller footprint, faster pump-down times (90 seconds vs 5-10 minutes), simpler operation, and lower maintenance requirements. For most applications, a desktop SEM provides everything you need.

Q: What resolution can I expect from the SNE-Alpha?

The SNE-Alpha achieves 5nm resolution, which is sufficient for the vast majority of materials science, life science, forensics, and quality control applications. Resolution depends on sample preparation, operating conditions, and the specific features being imaged.

Q: What magnification range is available?

The SNE-Alpha offers magnification from approximately 20× to 250,000×, allowing you to navigate your sample at low magnification and zoom in to nanoscale features. Magnification is continuously adjustable through the software.

Q: What types of samples can I image?

Almost any solid material can be imaged: metals, ceramics, polymers, composites, biological specimens, geological samples, electronics, and more. Conductive samples can be imaged directly; non-conductive samples typically need a thin conductive coating or can be imaged in low-vacuum mode. The chamber accommodates samples up to 70mm in diameter.

Q: What is EDS and do I need it?

EDS (Energy Dispersive X-ray Spectroscopy) identifies the elemental composition of your sample. If you need to know what elements are present—not just what your sample looks like—EDS is essential. It can identify elements from Boron to Uranium, create element distribution maps, and quantify composition. We offer integrated Bruker XFlash EDS detectors that work seamlessly with the SNE-Alpha.

Q: What other analytical options are available?

Beyond standard SE/BSE imaging and EDS, we offer several advanced analytical options: EBSD for crystallographic analysis, cathodoluminescence (CL) for optical properties and defect detection, Raman spectroscopy for molecular identification, and EBIC for semiconductor characterization. Our team can help you determine which options fit your applications.

Q: Can I add capabilities later?

Yes, the SNE-Alpha is designed for expandability. You can start with basic imaging and add EDS, EBSD, or other detectors as your needs grow. We can retrofit additional capabilities to existing systems.

Q: How much does a desktop SEM cost?

Pricing depends on the configuration (detectors, accessories, options). We provide customized quotes based on your specific needs. Contact us for a quote tailored to your application.

Q: What is included with the purchase?

Every SNE-Alpha includes the SEM unit, control computer with software, sample holders and stubs, basic tools, and consumables to get started. Professional installation, on-site training, and a warranty are also included. EDS systems include the detector, interface, and ESPRIT analysis software.

Q: Do you offer financing or leasing?

Yes, we work with several financing partners to offer lease and payment plan options. This can help spread the investment over time while you begin using the instrument immediately. Ask us about available financing during your consultation.

Q: What is the lead time for delivery?

Typical lead times are 4-8 weeks depending on configuration and current demand. We will provide a specific timeline when you place your order. Installation and training are scheduled at your convenience after delivery.

Q: What are the facility requirements?

The SNE-Alpha has minimal requirements: a sturdy bench or table, standard electrical outlets (110-240V), and a reasonably climate-controlled environment (temperature stable within a few degrees, moderate humidity). No special vibration isolation, water cooling, or compressed air is required. Avoid locations near heavy machinery or elevators.

Q: How large is the instrument?

The SNE-Alpha measures approximately 300mm (W) × 465mm (D) × 600mm (H) and weighs about 85 kg. It fits comfortably on a standard lab bench with room for the control computer and monitor alongside.

Q: Who installs the system?

Our trained service engineers handle installation. This typically takes one day and includes system setup, calibration, verification of performance, and initial training for your team.

Q: Do you offer training?

Yes, comprehensive training is included with every system. Training covers basic operation, sample preparation techniques, imaging optimization, and EDS analysis (if applicable). We tailor training to your team’s experience level and applications. Additional training sessions and refresher courses are available.

Q: How do I get technical support?

We provide ongoing technical support via phone and email. Our applications scientists can help with sample preparation questions, imaging optimization, and data interpretation. For hardware issues, our service team provides remote diagnostics and on-site service as needed.

Q: What is the warranty?

The SNE-Alpha comes with a standard warranty covering parts and labor. Extended warranty and service contract options are available for continued coverage and preventive maintenance. Contact us for warranty details.

Q: What ongoing maintenance is required?

Desktop SEMs require minimal maintenance compared to floor-model instruments. Routine tasks include periodic filament replacement (every 40-100 hours of use), chamber cleaning, and occasional pump maintenance. Annual service visits are recommended to ensure optimal performance.

Q: Who is NanoImages?

NanoImages is a U.S.-based provider of desktop scanning electron microscopes and analytical solutions. We partner with SEC Co., Ltd. (the SNE-Alpha manufacturer) and Bruker (EDS systems) to deliver complete microscopy solutions. With over 100 systems installed, we serve universities, research institutions, and companies across diverse industries.

Q: Where are you located?
