The conventional zero‐background holder technique has been adapted for handling small bulk samples by adding one‐axis mobility to a single‐crystal wafer using a Newport optical stage. Experiments showed that an a ‐plane sapphire crystal with a surface‐to‐crystal‐plane angle of ∼3° can be used as a zero‐background holder. Such a crystal is a viable alternative to the commercial Rigaku product and shows better performance in the intermediate angle range (2θ = 60–110° for Cu K α radiation). It has also been demonstrated that the proposed scheme of hardware stacking is operational.
