Optical Filters in Water Analysis
Optical Filters in Water Analysis How Are Optical Filters Used in Water Analysis? Every year, the Earth’s population consumes 4 trillion cubic meters of fresh water. After being carefully treated to fulfill the water-quality standards established by local governments, this drinking water is delivered through water delivery systems (WDS). These water delivery systems are susceptible…

Optical Bandpass Filters Fundamentals
Optical Bandpass Filters Fundamentals What Are Bandpass Filters? Bandpass filters are one of the simplest and most economical ways to transmit a well-defined band of light and reject all other unwanted radiation. Their design is essentially a thin film Fabry-Perot Interferometer formed by vacuum deposition techniques and consists of two reflecting stacks, separated by an…
