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.
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.
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.
As point-of-care molecular diagnostics transforms medicine by bringing sophisticated diagnostic testing to the patient, the need for compact optical and detection technologies is increasing. Highly integrated PixelSensor™ multispectral sensors fill this niche well, reducing the complexity, footprint, and cost of OEM instrumentation significantly.
Unlike traditional optical correlation techniques, ASychronous OPtical Sampling (ASOPS) offers a number of advantages in terms of resolution, speed, accuracy and precision. This white paper reports on how the technique of ASOPS can deliver these benefits, with particular emphasis showing the precision available.
