Optical Density (OD)

Optical Density (OD) is a logarithmic unit used to quantify the attenuation (blocking) of light as it passes through an optical component. In the context of optical filters and safety...

Angle of Incidence (AOI)

In optics and physics, the Angle of Incidence (AOI) is the angle measured between an incoming wave (such as a light ray) and the line that is perpendicular (normal) to...

中心波长

中心波长决定了光学带通滤波器的透射带的精确光谱位置。本文将通过一个清晰的步骤示例，讲解如何通过对 50% 透射率点处测得的截止波长和开启波长取平均值来计算这一关键参数。

汞弧灯

汞弧灯是一种气体放电灯，通过蒸发的汞产生电弧来发光。

长通二向色镜

长通二向色镜透射波长大于特定值（称为截止波长）的光，同时反射较短波长的光。

短通二向色镜

短通二向色镜透射波长短于特定值（称为截止波长）的光，同时透射波长较长的光。
