What is hyperspectral Technology?
Hyperspectral technology is a method that captures the spectral information of a target object within a specific spectral range with high spectral resolution. It provides detailed spectral data across multiple spectral intervals, from ultraviolet, visible, near-infrared, to even mid-infrared rang...Read more -
What are the precautions for using a spectrometer?
The miniature optical fiber spectrometer is a device that measures the intensity of spectral lines at different wavelengths using a photodetector. It is widely used in various fields, including environmental monitoring, industrial control, chemical analysis, food quality...Read more -
What can cause chromatic aberration?
In optical imaging systems, aberration refers to the deviation between actual imaging and ideal imaging. This deviation can arise from various factors, with chromatic aberration being a significant type of aberration. Chromatic aberration, also known as color aberration,...Read more -
What is dispersion of light expression?
Definition: Dispersion of light refers to the phenomenon where white light separates into different colors when passing through a medium (such as a prism), due to the medium’s varying refractive index for different frequencies of light, causing each color to refract at different angles. 1....Read more -
How do you explain light diffraction?
Diffraction is a physical phenomenon that occurs when light encounters an obstacle or passes through a small aperture (narrow slit), causing it to deviate from its straight-line path and bend around the obstacle to continue propagating. The resulting pattern of light and dark bands or rings is ca...Read more -
What is image distortion?
In optical imaging systems, distortion is an important type of aberration that describes the deformation between the actual image plane and the ideal image plane. Distortion not only affects the geometric shape of the image but can also negatively impact the visual quali...Read more -
What causes field curvature aberration?
In optical imaging, aberration is an important concept that cannot be ignored as it directly impacts the performance and quality of the imaging system. Field curvature, a type of aberration, significantly affects the flatness and sharpness of an image. This article explo...Read more -
What is meant by interference of light?
The discovery of light interference holds significant importance in the field of optics. In 1801, British physicist Thomas Young successfully observed the phenomenon of light interference in his laboratory, confirming the wave nature of light. This discovery was crucial ...Read more -
What is Coma Aberration theory?
In the field of optics, coma (also known as comet-shaped aberration or Coma Aberration) is an important aberration phenomenon that directly affects the clarity and resolution of imaging systems. This article will explore coma in detail, covering its definition, principle...Read more -
What is the mercury argon light source?
A mercury-argon lamp is a special type of gas discharge lamp that combines the characteristics of mercury vapor and argon gas to produce light. This lamp is typically made from a sealed quartz or glass tube filled with a small amount of mercury and a large amount of argon gas, with electrodes ins...Read more -
What is Gaussian image plane?
In the vast field of optical research, spherical aberration is a fundamental imaging error that significantly affects the performance of optical systems. This article delves into the definition, principles, and correction methods of spherical aberration from a profession...Read more -
What are neon lamps used for?
Neon Lamp is a type of discharge lamp filled with neon gas or other inert gases, primarily used for indicators, decoration, or lighting. Neon is a rare gas with a highly stable chemical nature, and when discharged, it emits a bright and vibrant red light, which is the mo...Read more
