What is a multi-mode fiber?
Multimode Fiber is a type of optical fiber communication transmission medium that allows light signals to be transmitted inside the fiber in multiple modes. Below is an introduction to the classification, numerical aperture, modes, and methods for measuring transmittance...Read more -
What Is Stray Light and How Does It Work?
The term “stray light” in a spectrometer refers to the presence of non-target wavelengths of light during spectral measurements, in addition to the intended spectral signal. These stray light sources can originate from various factors and have a significant impact on the measurement p...Read more -
What are the factors to consider when selecting fiber optic cable?
When choosing a suitable optical fiber for a fiber optic spectrometer, several key factors need to be considered to ensure the accuracy and reliability of spectral measurements. The following are some of the main selection points: 1. Fiber Parameters ● Fiber core diameter (core diameter) The core...Read more -

What is TEC cooling system?
With the rapid development of photoelectric sensing technology, machine vision endows AI devices with precise vision capabilities, not only refining the recognition accuracy of the shape of the object, but also relying on spectral detection technology to deeply analyze t...Read more -
External Triggering Options Instructions
Triggering is a feature that can be applied to many fiber optic spectrometers and is related to the general spectral process. The first type: an event outside the sampling system (a button or a pulsed laser) can trigger the spectrometer to start the data acquisition process. This type of trigger ...Read more -

What are narrowband filters?
A narrowband filter is an optical filter that allows light within a specific wavelength range to pass through while blocking other wavelengths. These filters are crucial in many scientific and industrial applications. Below is some basic information about narrowband filt...Read more -
Definition for Temperature Drift and Temperature Compensation
Electronic components usually have a certain temperature coefficient, and their output signals will drift with temperature changes, which is called "temperature drift". In order to reduce temperature drift, some compensation measures are used to offset or reduce the temp...Read more -
What is fiber optics?
The transmission principle of optical fiber is mainly based on the total reflection of light. Optical fiber is a kind of slender fiber made of glass or plastic, and its structure is mainly composed of three parts: core, cladding and coating layer. Fiber core: Located at ...Read more -
What is a longpass filter?
The longpass filter is an optical filter which allows light with wavelengths exceeding a specific threshold to pass through while absorbing or reflecting light of shorter wavelengths. This type of filter has a wide range of applications in many fields, including but not ...Read more -
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
