How do you calibrate the wavelength of the spectrometer?
Wavelength accuracy and repeatability are one of the important quality indicators of spectrometers,which have a significant impact on the correct use of the instrument and even experimental results. In addition, due to external factors such as temperature, humidity, air ...Read more -
What is the difference between array and linear array?
In the rapidly evolving field of optoelectronic sensing technology, machine vision, often referred to as the "keen eye" of artificial intelligence, has significantly enhanced our ability to perceive the precise dimensions and shapes of objects. Furthermore, through spect...Read more -
What is a Czerny-Turner spectrometer?
The C-T (Czerny-Turner) structure is very common in the field of spectral analysis, mainly comprising two forms: the crossed type and the symmetric type. Here is a detailed analysis of these two forms: Crossed C-T Structure 1. Structural Characteristics ● Folded Light Pa...Read more -
What is the principle of dichroic mirror?
A dichroic mirror, also known as a dichromatic mirror, is an optical component with special optical properties. It can reflect or transmit light at different wavelengths, hence the name "dichroic." This article provides a detailed introduction to the principles, characte...Read more -
What are the different types of reflectors?
Reflectors are optical devices capable of reflecting light, based on the law of reflection. When light strikes a surface, the angle of incidence equals the angle of reflection. ...Read more -
What are the classification of fiber optic spectrometers?
1 Emission Spectrum ● Principle: When a substance is excited by external factors such as heat, electricity, light, or magnetism, its internal atoms or molecules transition to higher energy levels and then return to lower energy levels, releasing photons to form a spectru...Read more -
How is SNR calculated?
The signal-to-noise ratio (SNR) of a spectrometer is a crucial performance indicator that reflects the relative relationship between the spectral signal and background noise. A higher SNR indicates less noise interference with the signal, resulting in higher quality spec...Read more -
What are different types of optical detectors?
1. Types of Photodetectors Photodetectors are sensors that convert light signals into electrical signals and are widely used in various fields, including medical imaging, industrial inspection, environmental monitoring, and communication. Based on their working principle...Read more -
What are the classification of detectors?
Detectors are devices capable of converting various forms of energy or physical quantities into observable or measurable signals. According to the type of physical quantity or energy they detect, detectors can be categorized in many ways. One common method is classificat...Read more -
What is the range of the spectrum of light?
1. Nature of Light Light is an electromagnetic wave that can propagate in a vacuum as well as in other media. Light exhibits wave-particle duality, meaning it can be viewed both as a wave and as particles (photons). The speed of light in a vacuum is constant at approxima...Read more -
What does a Raman probe do?
In modern scientific research, precise analysis of the microscopic structure and chemical composition of substances is crucial. Raman probes, as advanced analytical tools, provide scientists with information on molecular structure and chemical composition through their u...Read more -
What is the introduction of diffraction grating?
1. Introduction to Gratings Definition of Diffraction Grating: A diffraction grating is an optical element that can modulate the amplitude or phase of incident light waves in a spatially periodic manner, or modulate both amplitude and phase simultaneously in a spatially ...Read more
