視野を広げた、新しいラマン。快速筛选系统 RAMANview


“Ultra-wide field-of-view”, “Extended depth of focus”, “High spatial resolution”, “Ultra-long working distance”.
These 4 values inside the minimum body enable diverse Raman spectroscopic analysis.

More than 800 mm2 is analyzed without moving the sample.

RAMANview 针对立体显微镜物镜搭配了最优化的光学系统,具有极宽广的观测视野。 即使是 1cm 以上的大样品,也能清楚地看到全体图像,从而方便选定观测部位。 与用电动扫描台那种花时间的成像方式不同,RAMANview 采用了超高速的激光扫描,能完美地实现高速的大面积观测。

Be free from time-consuming focus corrections by extended focal depth

RAMANview的焦点深度大约为1.4mm(使用0.5倍镜头时)。 样品的表面即使有 1mm 或者 2mm 的高低差也不会产生模糊的拉曼成像。 这长焦深功能也可在块状样品的光谱测量中发挥其用武之地。 可以不受因测量场所不同而造成的误差以及包装袋等薄层的影响获得块状样品的光谱。

Tiny, micro scale components will be detected with RAMANview

The dedicated optical system creates a high precision spot size, which facilitates a spatial resolution of up to 2.5 μm (see right figure) with the 2x objective lens. RAMANview also stands for very fast Raman imaging in a micro scale range.

Ultra-long working distance extends the measurement scene.

RAMANview 的工作距离大约为 7cm( 使用 0.5 倍镜头时)。 因激光光束可以到达深容器底部的样品,扩大了拉曼光谱测量的适用场合。 因为镜头到样品表面的可取间距足够大,所以不用担心镜头碰到样品。 此外,RAMANview 也能进行实现穿透玻璃或密闭容器的测量。
