It is only in the last two decades that Raman spectroscopy has begun to realize its potential as an almost universally applicable analytical technique from materials and life sciences applications to point of care analysis.
This Application Note, from Ocean Optics, explores how absorbance spectroscopy and chemometric analysis are used for authentication and quality assurance in the production of alcoholic drinks.
Read how photoluminescence and electroluminescence spectroscopy are used to probe new material compositions for optoelectronic devices to explain their structure and kinetics. Herein, we present the results on Poly(3-hexyl) thiophene-2,5-diyl (P3HT) and [6,6]-phenyl C61 butyric acid methyl ester (PCBM) and specify the required instrumentation for steady-state and time-resolved photoluminescence and electroluminescence measurements.
Vortex Optical Coatings have developed processes for manufacturing Infra Red Linear Variable Filters (LVF). An LVF has a coating of wedged thickness, such that the spectral performance continuously changes as one travels along its length. They have been manufactured to cover the following ranges, 900-1700 nm, 1200-2500 nm and 2500nm to 5000nm. This document presents their general properties, the performance of a 900-1700 nm LVF, some applications and comments on producing them in volume.
Quality and precision is a fundamental part of optical component manufacturing and an appropriately specified optic is crucial to get the performance your system requires. The optical surfaces in a system are the main contributors to transmission loss, wavefront errors and aberrations. In addition mechanical specifications can also impact the alignment and stability of an element and consequently the overall system performance.
