Asahi Spectra 高性能滤光片,多种类可选
日本Asahi Spectra始创于1970年,于日本东京成立。因其在离子辅助沉积 (IAD) 和离子束溅射 (IBS) 等真空沉积技术等技术的多年深造,使其具备了硬镀膜、对环境(湿度、低温或高温、热冲击或真空)的出色耐久性和光谱稳定性的出色能力。
日本Asahi Spectra的主营产品分滤光片和光源仪器两大类。而其中,日本Asahi进口滤波片,以其高性能,成本性价比高著称。在滤波片的类型上主要分有短通滤光片,长通滤光片,带通滤光片,中性灰度镜(又称为中灰密度镜或者中性密度滤波片),超冷滤波片。其工作波段囊亏常用UV紫外波段,VIS可见光波段和IR红外波段。滤波片的材质以熔石英为主,尺寸分为两种:φ25mm的圆片,50*50mm的方片,镜片的厚度均为1mm。
Asahi带通滤光片:
带通滤光片通常用于传输明确范围的光谱波段,同时抑制比传输波段的长的波长和更短的短波长侧。 日本Asahi Spectra的涂层设计基于多腔谐振器。 因此,其带通滤光片在窄通 10nm 波段之外具有非常陡峭的斜率和非常高的衰减。

Asahi短通滤光片:
日本Asahi进口滤波片的短通滤光片通常用于隔离范围光谱区域。 Asahi滤光片的作用是在指定波段上传输比截止波长短的波长的能量,并阻挡比截止波长更长的波长的能量透射。此外,通过与长通滤波片一起使用,短通滤光片可用于自定义带通滤波。 Asahi Spectra 提供多种波长范围广的短通滤光片:紫外线、可见光或红外线波长。

Asahi中性密度滤波片
中性密度滤光片(又称中性灰度滤波片或者中灰密度镜)是反射型 ND 滤光片,用于控制光强度。 镀铬层主要通过反射和部分吸收来衰减光。 Asahi的 ND 滤光片旨在保持光谱均匀性能,尤其是在可见光范围内,而不会改变能量的相对光谱分布。 共有6种衰减率可供选择。
