A Brief Guide to Optical Filters for Earth Observation

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...

Critical Filters Used in Raman Spectroscopy

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...

What Optical Filters are Used in qPCR Instruments?

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...
