Photodetectors are devices used for the detection of light – in most cases of its optical power. More specifically, photodetectors are usually understood as photon detectors, which in some way utilize the photo-excitation of electric carriers; thermal detectors are then not included by the term and are also not treated in this article.   Photodetectors usually deliver an electronic...

What is a Photodiode? It is a form of light sensor that converts light energy into electrical energy (voltage or current). The photodiode is a type of semiconducting device with a PN junction. Between the p (positive) and n (negative) layers, an intrinsic layer is present. The photodiode accepts light energy as input to generate electric current. It is also called a Photodetector, Photo Sensor,...

An Optical Delay Line (ODL) is an electric-optic-electric instrument. It performs fixed time delay(s), between a few nanoseconds up to several hundred microseconds, for signals from 10MHz up to 40GHz and more. There are low-frequency ODL versions ranging from 10MHz to 6GHz. The high-frequency ODLs versions are up to 8GHz, 15GHz, 18GHz, 20GHz, and 40GHz....

What are progressive cavity pumps? Progressive cavity pumps, also known as PC pumps, progressing cavity pumps, eccentric screw pumps, and mono pumps are a type of rotary positive displacement pump designed for the conveying of liquids and sludges from 1cst to 1Million. They handle not only viscous fluids and solids but also gassing or multiphase liquids containing gas slugs typical during crude...

A progressive cavity pump is a type of positive displacement pump and is also known as a progressing cavity pump, progg cavity pump, eccentric screw pump or cavity pump. When its rotor rotates, it transports fluid through the pump through a series of small, fixed-shaped, discrete cavities. This causes the volume flow to be proportional to the...
