What is the difference between FSI and BSI?
Spectral data, a rich information carrier intertwined with the dual characteristics of wavelength and light intensity, is gradually penetrating and profoundly influencing many frontier fields, including industrial manufacturing, medical diagnosis, and modern agriculture,...Read more -
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 -
Application of Fiber Optic Spectrometers in Fluorescence Measurement
1. Principle of Fluorescence Measurement When a substance is irradiated with incident light of a certain wavelength (typically ultraviolet or X-ray), it absorbs the light and enters an excited state. The substance then emits light of a longer wavelength than the incident...Read more -
Application of near-infrared fiber optic spectrometer in plastic type identification
1 Introduction With the rapid development of the plastics industry, the application scope of plastic materials is becoming increasingly widespread. However, this growth has also led to an increase in plastic waste and the associated challenges of its treatment. Rapid and...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 -
Application of Near-Infrared Spectroscopy in Petrochemical Product Analysis
1 Background of Near-Infrared Spectroscopy in Petrochemical Product Analysis Traditional detection methods are limited by factors such as flow, pressure, and algorithms. The application scope of petrochemical product analysis using spectroscopy is increasingly broad. Ato...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
