Analytical equipment that utilize embedded spectroscopic techniques is used to acquire physical and chemical information of materials, digitize and organize the data, analyze the data and deliver useful information for follow-up actions. Critically important to our individual well-being and health, analytical equipment is used to measure a wide range of parameters from inorganic materials (solid/liquid/gas) to organic materials such as tissue, blood and saliva. Traditionally, the technologies used to make these measurements were quite large. However, as semiconductor technology continues to advance, improvements yield smaller, lower cost components that can often be embedded within a compact device while occupying a minimal footprint and offering ease of use. Immediate analyses can now be made in the field with portable equipment or on the desktop in a medical setting.
