Optical technologies are increasingly central to the growth of satellite communication constellations. These technologies not only facilitate diverse satellite networks and ground-to-satellite connections but also promise enhanced anti-interference through space laser...

An increasingly interconnected world with more devices online than ever before means the demand for low latency, high capacity, secure, and uninterrupted internet connectivity is still growing.1 As the world’s leading supplier of optical filter solutions, Iridian...

Infrared (IR) sensing uses infrared-sensitive optical components to detect light in the IR region of the electromagnetic spectrum. IR sensing is now widely used in motion detection, machine vision and industrial automation, agriculture, and medical applications1 as it...

While Raman spectroscopy is widely used in many areas of analytical and medical sciences, including in situ and in vivo measurements,1,2 a challenge for Raman spectroscopy measurements is the inherently weak nature of the Raman effect. Most modern Raman spectroscopy...

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...

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...

Etalons are a type of Fabry–Pérot interferometer – an optical cavity made from two parallel reflecting surfaces. They can act as optical filters since only the frequencies matched to the resonant frequencies of the cavity can pass through the cavity. As a result, they...

Long pass filters, sometimes referred to as long pass edge filters, are designed to transmit wavelengths within a given wavelength range. This band is defined by the filter’s cut-on edge which essentially blocks frequencies shorter than the specified edge wavelength....

Dichroic filters are designed to selectively allow wavelengths within a specific transmission band to pass through while reflecting all other colors and for beam steering purposes. They are particularly useful in optical applications where the detector is...

A simple approach in optical data communication is the use of a pair of optical fibers for a single channel transmission. The fiber pair provides the two directions for transmitting the data. Basically, one pair of fiber is equivalent to one data channel and the light...
