产品说明
等边色散棱镜(Equilateral Dispersion Prisms)三个角的角度均为60°,可以将不同波长的光分开,例如色散棱镜代替衍射光栅,用于将白光分成可见光谱。色散棱镜一般以最小偏向角使用。在最小偏向角条件下,某一波长的入射光通过棱镜时与底面平行,而且相对于各自界面的棱镜面法线测量时,入射角等于折射角。
图知光学提供尺寸为10mm-50mm的色散棱镜,我们也提供各种材质基片的色散棱镜,应用从紫外到远红外的不同波段。包括H-F4和H-F13光学玻璃,以及红外基片氟化钙 (CaF₂)。氟化钙 (CaF₂) 属低折射率材料,同时具有介于0.18 - 8μm之间的高透射率,是应用于紫外光到红外光谱方面的理想选择。我们也可以根据您的需求定制满足您使用要求的色散棱镜。
最小偏转角的定义如下图所示当 α=β 时,棱镜内的折射光线 与底面平行时入射光和出射光的偏转最小。下图的公式仅限于折射率小于 2 的材料。
