How is Film Thickness Measured?

A thin film thickness measurement is made by measuring the interference between the light from the top interface ad the bottom interface. Essentially, a thin film is a type of layered material that has a variety of thickness ranges. The main reason why you may need to understand thickness measurements is so you can have complete control over the creation of optimal product functions and designs. This includes microspectrophotometers for microscopic sampling areas, where you need the right thickness measurement tools. Here is what you need to know when making a thin film measurement.

What is Resonance Raman Spectroscopy?

Raman spectroscopy is an analytical method fundamentally concerned with inelastically scattered light, which indicates a critical interaction between light and matter. This information is crucial for many applications. By examining the scattered light, analysts can obtain in-depth details about a sample's chemical structure and molecular interactions. This technique provides numerous benefits to its intended applications. However, it can be drastically improved by using resonance Raman spectroscopy. This blog post will overview resonance Raman spectroscopy and its applications.  

Key Tools for Film Thickness Calculation

Thin films are ubiquitous in modern technology, forming the functional basis of end products used in consumer electronics, high-end energy harvesting systems, and much more. Ensuring the quality of materials deposited in minuscule layers, often approaching nanoscale thicknesses (nm), is paramount in quality assurance and control (QA/QC). Although there are many quality benchmarks in thin film engineering, film thickness is one of the most critical. Additionally, issues with film thickness can also cause problems with the costs and processes associated with coating. 

How Does MicroRaman Work?

MicroRaman spectroscopy is a light scattering technique that utilizes a Raman microscope spectrometer to analyze live cells. The analysis is conducted by identifying molecules and their functional groups. It is a technique based on Raman spectroscopy, where the interaction between light and matter is studied after the light has been scattered. MicroRaman spectroscopy utilizes a more specific Raman spectrometer, and throughout this blog post, we will look at the equipment associated with MicroRaman spectroscopy in-depth.

When to Use a Raman Microscope Spectrometer

Raman microscopy is an extremely powerful analytical method. Combining the unique chemical identification capabilities of Raman spectroscopy with traditional confocal microscopy opens an array of applications in a wide range of fields. But what is a Raman microscope spectrometer, and when might you use one?
