A low‐temperature camera for single‐crystal X‐ray investigation between 28 and 350 K has been developed for a modified Weissenberg goniometer. Cooling is provided by a double‐stage cryorefrigerator which is firmly attached to the low‐temperature camera. Stranded copper cables ensure a flexible heat transfer between crystal and cold finger allowing a crystal rotation of 180°. Compared to the usual Weissenberg technique almost no further limitation is given on the accessible angular range of the scattered radiation.
