" About 1930, our laboratory had obtained a large concave grating and set it up in a Runge-Paschen mounting. "
- Frits Zernike

In the context provided by Frits Zernike's statement, he refers to a significant moment around 1930 when his laboratory acquired and installed an extensive concave grating on a specialized optical setup called the Runge-Paschen mounting. This apparatus was designed for detailed spectroscopic analysis, allowing researchers to study the wavelengths of light emitted or absorbed by atoms and molecules.

The deeper significance of this quote lies in its reflection of the advancements made in experimental physics during the early 20th century. Zernike's mention of a large concave grating underscores the importance of precise instruments for scientific inquiry, especially as experiments became more complex and required higher levels of accuracy and detail. The Runge-Paschen mounting was crucial for achieving these goals by providing an effective means to disperse light into its component wavelengths. This setup not only facilitated groundbreaking research but also symbolizes a critical juncture in the development of spectroscopy, a field that has since become fundamental in understanding atomic structure and molecular interactions.

Frits Zernike was a renowned Dutch physicist who made significant contributions to optics and physics. He is best known for his invention of phase contrast microscopy, which earned him the Nobel Prize in Physics in 1953. His work greatly enhanced scientists' ability to observe transparent samples such as living cells without staining them, thus revolutionizing biological research. The quote provided reflects Zernike's deep involvement not only with theoretical developments but also with the practical aspects of laboratory instrumentation, showcasing his comprehensive approach to scientific inquiry and innovation.
