Factors Influencing SEM Pricing
Type and Configuration
The type of SEM—whether it’s a standard, desktop, or field emission model—plays a significant role in its pricing. For instance, new standard SEMs can range from $50,000 to over $1,000,000, while desktop models are generally more affordable.
Resolution
Resolution is a crucial factor affecting SEM prices. Higher-end models that can achieve resolutions below 1 nm are significantly more expensive compared to entry-level models that offer resolutions around 15 nm. This capability is essential for advanced applications in nanotechnology and materials science.
Accessories and Features
Optional accessories such as specialized detectors, sample holders, and imaging software can add to the overall cost of the SEM. Additionally, features like automated sample handling and environmental control can enhance functionality but also increase the price.
Condition: New vs. Used
Purchasing a used SEM can lead to significant cost savings. Prices for used SEMs can range from $2,500 to $550,000 depending on the condition and specifications. This option is appealing for institutions with budget constraints.
Technical Features Comparison of SEMs
| Feature | Standard SEM | Desktop SEM | FE-SEM | Dual Beam SEM | Tabletop SEM |
|---|---|---|---|---|---|
| Resolution | 15 nm – <1 nm | 50 nm – 1 µm | <1 nm | 5 nm – <1 nm | 20 nm – 1 µm |
| Electron Source | Tungsten or LaB6 | Tungsten | Field emission | FIB + SEM combo | Tungsten |
| Max Sample Size | Large | Small to Medium | Small | Medium to Large | Small |
| Maintenance | High | Moderate | High | High | Low |
| Operational Complexity | High | Low | High | Very High | Low |
