SynopsisNegative induction phenomenon (also known as photodegradation) refers to the formation of defect centers within a fiber, resulting in a decrease in transmittance. When the fiber is exposed to light with a wavelength below 300 nm, these defect centers are forme.....
SynopsisNear Infrared (NIR) analysis is a spectroscopic technique that utilizes the NIR region of the electromagnetic spectrum or the wavelengths between 700nm and 2500nm. NIR analysis has many applications including food, agricultural, environmental, chemical and pha.....
SynopsisThe external cavity semiconductor laser controller is a device used to control and operate external cavity semiconductor lasers. It typically includes the following functions and components: 1 Laser driver circuit: used to provide appropriate current and volta.....
SynopsisA tapered optical amplifier is an optical device that amplifies an incoming optical signal. Its structure resembles a cone, with a tapering shape. When the optical signal passes through the tapered optical amplifier, the intensity of the light increases due to.....
SynopsisA laser frequency stabilizer is a device used to stabilize the output frequency of a laser. It maintains a stable frequency output by feedback-controlling the frequency of the laser. A laser frequency stabilizer usually consists of the following main component.....
SynopsisA modulated thermography analyzer is an instrument for thermal analysis that analyzes the properties of a sample based on the temperature change that occurs when the sample is irradiated with light. The instrument generates periodic temperature changes by peri.....
SynopsisThe non-contact metal film thickness measuring instrument is an instrument used to measure the thickness of metal films. It uses a non-contact measurement method to measure the metal thin film through optical or other physical methods without direct contact wi.....
Synopsis A multi-wavelength ellipsometer is an instrument used to measure the optical rotation of a substance, which can simultaneously measure the optical rotation at different wavelengths. The instrument measures the optical rotation by passing polar.....
SynopsisAn optical microscope for materials is an instrument used to observe the microstructure of materials. It uses the optical principle to magnify and illuminate the sample through the objective lens, eyepiece and light source, so as to observe the shape, tissue s.....
SynopsisNano surface profiler is an instrument used to measure the surface topography and roughness of materials. It uses scanning probe microscope technology to scan and image the surface of the material at the nanometer scale, and then obtains the data of surface mo.....
