Spectrometry

A spectrometer consists of four main building blocks: a light source, optics, a detector, and some algorithm that converts the spectral data meaningful information. In this blog I have organized some of the information that is required for building a handheld and mobile phone connected spectrometer - from the perspective of spectrometry. The actual putting together of the electronics in covered in my blog on arduino and the casing into which the electronics is put in my blog on 3D printing (or reprap) Where RepRap is short for Replicating Rapid-prototyper and really means a 3D printer that can print out a replica of itself. It is possible to get all the parts of a spectrometer as single pieces, or as a fully assembled spectrometer. It is also possible to get different levels of assembly, like for instance the optics and a detectr, or a detector and a light source, etc.

Light source

The light source can be the sun, or any light bulb, led or other artifical light source. An ideal light source emits equally intense over the full range of wavelengths of the sensor. That is seldom possible. Light source alternatives are listed, discussed and analysed under the heading _light sources_.
