Precision linear stages play a critical role in various applications that necessitate high levels of accuracy and precision. These stages are frequently utilized in industries such as laser cutting, scanning, digital printing, and electronics assembly and inspection. They are also deployed in processes such as AOI (Automatic Optical Inspection) and laser micro-machining, which demand ultra precision and accurate scan motion. In medical and scientific equipment, precision linear stages are pivotal in ensuring accuracy and repeatability. In any industry or application, utilizing precision linear stages is crucial for achieving desired outcomes and delivering top-quality output.

The G165-IL Series is a cutting-edge solution that leverages the advantages of ironless linear motors. One of the key benefits of these motors is their high precision and accuracy, which are critical factors in many industrial applications. The absence of a ferromagnetic core in the stator eliminates cogging and any interaction between the stator and rotor magnetic fields. This produces incredibly smooth and precise motion, making it an ideal solution for applications where high accuracy and precision are essential. The G165-IL Series delivers unparalleled performance, making it a reliable and efficient solution for applications requiring a high degree of accuracy and precision. Additionally, its compact design and high power density make it ideal for use in applications where space is limited. Whether it is for semiconductor manufacturing equipment, medical devices, or robotics, the G165-IL Series delivers the precision and accuracy that these industries demand.

Spectrophotometers are otherwise known as UV-Vis spectrometers. The output of a spectrophotometer is usually measured in the absorption spectrum of the sample. There are four main performance indicators you need to consider before choosing a spectrometer or spectrophotometer:

SpectrometerMachine

Scientists rely on spectrophotometers to give them reliable wavelength results with precious samples as small as 1uL. Spectrophotometers are capable of measuring the diffusivity of light ranges anywhere between 200-2500nm within the electromagnetic radiation spectrum. The following scientific disciplines depend on spectrophotometers to make advancements:

Most spectrophotometers are either single-beam or double-beam. Single-beam spectrophotometers are used to examine relative light intensity before and after a test sample is introduced, while double-beam spectrophotometers are used for comparing light reference paths and the substance being measured. Single beams are overall more compact and have a higher dynamic range, yet double beams are preferable in environments that require equipment that is less sensitive to fluctuations.

What isspectrometerin physics

Spectroscopy refers to the study of radiated matter and how it interacts with radiated energy. As matter absorbs energy, the material becomes excited and causes a visual change that we recognize as color on the visible spectrum. While spectroscopy studies how radiated matter interacts, spectrometry is the study of the color spectra produced by that radiated matter.

To use a spectrometer, researchers often start by loading a sample of a particular substance and vaporizing it. As light passes through the vaporized substance, the spectrometer splits the light into its discrete wavelengths. It creates a spectrum of separate colors, similar to the rainbow created with a prism. These different-colored wavelengths are useful for determining the nature of the substance in the spectrometer.

Spectrophotometers quantitatively measure light intensity using wavelengths. They contain a spectrometer inside to quantify the amount of light and the type of waves that pass through the instrument. Light experiences the following process in a spectrometer:

A spectrometer is an instrument that detects and analyzes light waves to measure a substance’s physical characteristics over a spectrum.

Since all spectrophotometers contain a spectrometer, there are many similarities between the devices. Both instruments measure light in nanometers, with the visible range falling between 380-780 nanometers and the ultraviolet range falling from 10-380 nanometers. Like mentioned previously, spectrometers measure the radiated matter of light, while spectrophotometry measures the color it produces.

Spectrometers and spectrophotometers are used alongside each other in disciplines including chemistry, biology and pharmaceuticals. Since all spectrophotometers contain a spectrometer, you can frequently use a spectrophotometer for all of your sample analysis needs. With a spectrometer and spectrophotometer together, you can study particle interactions, composition and colorimetry.
