亮点

适用性强

仪器可以配置各种光源，从Mo封闭靶光源，到最新的同步辐射光源，仪器可以配置各种探测器，比如mar345成像板探测器，SX-165/MX-225 CCD探测器，PILATUS4 260/1M或者EIGER2 R 1M/4M像素探测器.

自动光束校准

由于万向悬架技术的应用，及内置电离室和完全电机驱动化的应用，此仪器通在相应的操作界面，就可自动进行光束校准.

反向PHI 的模式

内置的CHI 旋转, 可使装在PHI 角上的测角头转到90度朝下垂直的方向，可以非常方便的装卸晶体.

内置视频

内置的视频摄像头将会实时监视样品中心位置的2 x 1.5 mm区域范围，并将其视频图像传入到控制用的计算机上，以使晶体对中更简单易行.

真正的2theta角

带动2theta的电机，可使探测器抬高30度角度.

样品测试的低温环境最优化

Mardtb为一系列低温装置提供了固定的支架（例如Oxford Cryosystems, Oxford Instruments 等等），可调节冷气流，来确保样品不结霜和除霜.
