## Description

This MCP server provides specialized tools for thin-film characterization. It allows AI agents to process optical measurement data to determine physical properties of materials. Use `calculate_single_layer_thickness` to find the thickness of a uniform film using interference patterns. Use `analyze_ellipsometry_data` to extract both thickness and complex refractive index (n and k) from polarization measurements. For complex stacks, `calculate_multilayer_thickness` resolves individual layer thicknesses. You can also use `validate_optical_constants` to check if provided n and k values are physically plausible.

## Tools

### analyze_ellipsometry_data
Analyzes ellipsometry data to find thickness and optical constants (n and k)

### calculate_multilayer_thickness
Calculates the thickness of individual layers in a complex multi-stack system

### calculate_single_layer_thickness
Calculates the thickness of a single uniform thin film based on interference data

### validate_optical_constants
Validates if provided refractive index and extinction coefficient are physically plausible

## Prompt Examples

**Prompt:** 
```
What is the thickness of a single uniform thin film with wavelengths [500, 510, 520] and intensities [0.8, 0.7, 0.6], given a refractive index of 1.5 and substrate index of 1.0?
```

**Response:** 
```
The calculated thickness of the thin film is 125.4 nm with an uncertainty of 0.2 nm.
```

**Prompt:** 
```
Analyze this ellipsometry data: psi [10, 12], delta [5, 7], wavelengths [550, 560], and substrate index 1.5.
```

**Response:** 
```
The film thickness is 45.2 nm, with a refractive index of 1.45 and an extinction coefficient of 0.01 at 550 nm.
```

**Prompt:** 
```
Is a refractive index of 2.5 and extinction coefficient of 0.001 plausible for a dielectric material?
```

**Response:** 
```
Yes, these values are physically plausible for a dielectric material.
```

## Frequently Asked Questions

**What kind of data is required for thickness calculation?**
For single layers, you need arrays of wavelengths and interference intensities. For ellipsometry, you need psi and delta values along with wavelengths.

**Can I analyze multi-layer stacks?**
Yes, the `calculate_multilayer_thickness` tool is designed to resolve individual thicknesses within a complex multi-stack system.

**How do I verify if my optical constants are correct?**
You can use the `validate_optical_constants` tool to check if the refractive index and extinction coefficient are physically plausible.
