Macromolecular crystallography goniometer

  • What is the history of the goniometer?

    The first known use of a primitive version of the modern-day goniometer was by a Dutch physician and mathematician named Gemma Frisius, who used it to calculate and record the position of celestial bodies with respect to Earth..

  • Goniometer Types
    Universal goniometers come in two kinds: long arm and short arm.
    Universal goniometers are typically used by physical therapists.
    Short arm goniometers are used to measure the angle of small joints, such as the elbow or ankle.

Jun 15, 2013A novel miniaturized κ-goniometer head, the MK3, has been developed to allow macromolecular crystals to be aligned. It is available on the 
Most macromolecular crystallography (MX) diffraction experiments at synchrotrons use a single-axis goniometer. This markedly contrasts with small-molecule 

What is a goniometer used for in crystallography?

In crystallography, goniometers are used for measuring angles between crystal faces

They are also used in X-ray diffractionto rotate the samples

The groundbreaking investigations of physicist Max von Laueand colleagues into the atomic structure of crystalsin 1912 involved a goniometer

What is a Type C motion goniometer?

The DECO 27 is a dedicated type C motion goniometer with the sample held vertically (base-up or base-down), which meets the requirements of CIE S025 and IES LM-79-19 for a fixed burning position

Type C motion goniophotometers avoid tilting the sample with respect to gravity during a scan

What type of goniometer should I use for photometric measurements?

Schematic drawings and a description of the different types are shown in Figure 1

For photometric measurements of products intended for general lighting purposes it is recommended to use a type C goniometer
