美国ASI浸没式物镜,显微镜物镜,浸油物镜,物镜调焦镜头 Applied Scientific Instrumentation光片照明显微镜
ASI和Special Optics开发了两种倾斜物镜，用于对清除的组织样本进行光片显微镜检查，包括ASI的ct dSPIM。由于独特的弯曲第一表面，这些物镜在没有校正套环的任何折射率介质中工作。它们对于浸泡在包括DBE和BABB在内的苛刻介质中是稳健的
Applied Scientific Instrumentation双选择性光片照明显微镜Ct-dSPIM是专业为清除的组织样本成像设计的双视图选择性光片显微镜SPIM,适合大尺寸样品成像,应用于各种清除组织样本成像，包括整个小鼠大脑和切片的清除组织成像。
