Bandpass filters are optical filters that only let a selected range of frequencies through. Bandpass filters are used for many optical applications in telecommunications, satellite communications and data transfer for light modulation. This article will explore some...
Bandpass filters are a crucial component in many optical devices, providing a means of filtering out undesired wavelengths of light. Myriad applications use bandpass filters, including telecom, spectroscopy, and remote sensing. How do bandpass filters work? A bandpass...
Research astronomers around the globe observe objects that are millions of light years away from the earth, but deep sky observations are not the only area of interest. Fascinating discoveries are also made on: our nearest star, the sun; planets in our solar system;...
Observing the earth via satellites with imaging devices provides information for numerous applications. The fundamental concept behind optical earth observation is wavelength discriminated imaging from a large distance to the earth’s surface. This approach delivers...
Raman spectroscopy is an analytical method based on the detection of scattered light from a sample. Only a small fraction of light that is scattered is suitable for Raman spectroscopy; around 1 in 10 million incident photons induce a Raman scattered photon. Generating...
To conduct data analysis of nucleic acid samples, typically DNA, a reasonable amount of DNA material is essential. Today’s standard approach is to replicate very small samples of specific DNA to obtain sufficient quantities that allow detection or identification for...
