![]() Lead-free flint glass usually has a “N” before their name. Some types of flint glass are: F, LF, SF, KF, BaF, BaLF. Flint glass has some lead and a particular high chromatic aberration (described by an Abbe number below 50), and high refractive index (usually above 1.55). The negative component is usually made of what is called “Flint glass”. The basic idea is that both lenses will compensate their respective dispersions and cancel each other. As mentioned before, the achromatic doublet has two lenses: a negative lens (concave) and a positive one (convex). A way to do this is by using an achromatic doublet. In order to reduce chromatic aberration, we need to find a way to match the lens focal length regardless of the wavelengths we are using. 50MM Chromatic Aberration on a Biconvex Lens That basically means that if we have a biconvex lens made with BK7, it will focus red and blue light at different points, resulting in chromatic aberration. For example, BK7 has a refractive index of 1.5228 at 480 nm (blue) and of 1.5131 at 700 nm (red). Chromatic aberration is the effect caused by the change in refractive index for a given material at different wavelengths. Chromatic Aberrationįirst, we need to understand what is chromatic aberration and why it occurs. Why these shapes and materials? We will try to explain the reason behind this structure. At its most basic, it is a two lens system configuration where one lens is a concave lens, usually made of a flint glass, and the other is a convex element, usually made with crown glass. It is used to reduce chromatic aberrations. We regard such understanding between the analysts' and programmers' worlds as essential for future improvements in analytical software.One of the most common optical structures is the achromatic doublet. Further specific examples of data analysis are presented, such as signal recognition, chromatogram smoothing and signal area calculation. The principles behind this implementation are described in detail for two modules-the ‘ chromatogram comparison’ and ‘signal recognition’ modules. This data-handling bottleneck is resolved in Achroma. ![]() Specifically, existing software enables the data analysis from continuous-flow mixing systems monitoring enzyme– inhibitor reactions only manually and indirectly. Achroma was originally programmed to circumvent problems with mass spectrometric vendor software in the analysis of data from new experimental strategies. Analytically, Achroma software is a tool to handle typical and untypical mass spectrometric data. ![]() Finally, every module is embedded within Achroma as a small “stand alone” software application. Typically, each module delivers just one specific function to the user. Furthermore, Achroma has a modular structure and each module has its own MVC architecture. Achroma is based on a model-view-controller (MVC) software architecture. Achroma is a software tool for the analysis of spectrometric data it is our hope that explaining the software strategy and the working modules behind Achroma may give analysts a better understanding of how (bio-)informaticians work out software solutions, thus facilitating the interaction between these two expert groups. Bioinformaticians typically program these software tools however, analysts and bioinformaticians have distinct views on these data. Today, (bio-)analytical researchers use various software tools for improving data analysis and the evaluation of their experimental results.
