BOROFLOAT33 硼硅酸盐玻璃详解及应用指南

BOROFLOAT33 是施玻特（SCHOTT）公司对一种硼硅酸盐玻璃的命名，该玻璃采用独特的微浮法（microfloat）工艺制造。它卓越的热学、机械、化学和光学性能，使其在众多应用中表现出高度的多功能性和重要地位。

SCHOTT ZERODUR

SCHOTT ZERODUR is a lithium aluminum silicon oxide glass-ceramic of zero porosity. Glass Ceramics are manufactured from controlled crystallization and nucleation of glass substrates, resulting in its mixed inherent properties of both glass and ceramic. Among them, SCHOTT ZERODURis iconic for its near-zero coefficients of thermal expansion (CTE), which is a result of its counterbalancing microscopic system and the glass matrix.

What is Second Harmonic Generation (SHG)

The application of the Second Harmonic Generation (SHG) technique is boosting currently. The technique has been utilized extensively as a measure to obtain laser light with short wavelengths which are not directly procurable, for example, 532nm green output for Nd: YAG lasers, or ultra-violet lights with further SHG. The equations and definitions of second harmonic generation are given in this article to deliver an elaborate theoretical explanation about shg.

Optical Basics: What is FOV (Field of View)

For optical imaging instruments and components, understanding the basic concept of FOV (Field of View) is fundamental for selecting the appropriate optical lenses and components that meet your specific requirements. Here Shalom EO will state the definitions, the equations, and the real-life interpretations of these concepts.
