Single crystal X-ray diffractmator is set up on a 2θ optical bench. Working range of 2θ is from 12.5 to 33.5 degree. A goniometer for mounting sample crystals has a high precision, high speed rotation axis with XYZ stages. A conventional sample pin for cryogenic condition with magnetic base can be mounted on the fore-end of the goniometer. Camera length (sample:detector length) could vary from 90 - 340 mm. Two large 2D detector, ADSC Q315r and PILATUS 1M, and cryocooler system are available.
