PMT vs. CMOS/CCD Technology: Unveiling the Best Detector for OES Analysis Optical Emission Spectrometers (OES) have evolved from using Photomultiplier Tubes (PMTs) to CCD and CMOS detectors, which offer significant advancements. While PMTs were once industry standard, they are limited by size, energy consumption, and the need for multiple detectors per wavelength. CCD/CMOS detectors are compact, covering thousands of wavelengths with greater sensitivity, precision, and scalability. CMOS technology has surpassed CCD and PMT, delivering superior performance in high-end spectrometers, with benefits such as Time-Resolved Spectroscopy (TRS) and Single-Spark Analysis. Today, CMOS detectors are widely adopted due to their high precision, lower detection limits, and greater flexibility, positioning them as the future of spectrometry. #CCDTechnology #OpticalEmissionSpectrometers #AdvancedDetectors #SpectrometerTech #TechnologyEvolution #OESDetectors #DetectorInnovation #CMOSFuture #AnalyticalTechnology #FutureOfSpectrometers #ScienceAndTech #MetalPower https://www.metalpower.net/oes/pmt-ccd-cmos/

Laser Treatments for Pigmentation The science behind the function of laser treatment is ‘selective photothermolysis’ which signifies the ability of a laser to regulate light frequency leading to heat production by destroying the selective tissue. There are various wavelengths of light, one of which is chosen as per the color shade of skin/hair as the case may be. Know more: https://www.sakhiyaskinclinic.com/laser-treatment-for-pigmentation/

https://www.glsun.com/article-p114-otn-principles-and-equipment-introduction.html WDM Principle Wavelength Division Multiplexing: Multiplexing optical signals of different wavelengths into the same optical fiber for transmission, this method is called wavelength division multiplexing (WDM). Features: Multi-wavelength multiplexing/high-speed long-distance transmission/optical layer monitoring and management. Coarse wavelength division multiplexing (CWDM): The wavelength interval is 20nm. With the development of technology, more and more optical signals can be multiplexed, and dense wavelength division multiplexing technology has emerged. Dense wavelength-division multiplexing (DWDM): Wavelength interval is less than 0.8nm. OTN - Optical Transport Network Optical Transport Network (OTN) is defined by recommendation G.709, provides a network-wide framework that adds SONET/SDH-like features to WDM equipment (also known as Wavelength Switched Optical Network equipment, or WSON equipment). It creates a transparent, hierarchical network designed for use on both WDM/WSON devices and TDM devices. It provides an efficient way to transport, switch, and multiplex different services onto high-capacity wavelengths across the optical network.
