GMx series mounts

Siskiyou has introduced a new range of diffraction grating mounts, the GMx series, which combine rotational adjustment of square components in all three axes and support both reflective and transmissive optics. 

GMx mounts can hold 12.5mm, 25mm and 50mm square optics of any thickness greater than 2mm, and offer up to 8 degrees of total rotation in each axis, with a resolution as low as 3.2 arcseconds. All adjustments are accessed from the top of the mount to facilitate their use in space-constrained systems and instruments. The mounts can be either table- or post-mounted for maximum operational flexibility and convenience. 

Unlike simpler optics like spherical lenses and mirrors, the optimised use of diffraction gratings requires the ability to precisely and independently adjust their alignment in three orthogonal axes. The compact GMx mounts avoid the need for bulky assemblies comprised of separate axial adjusters, while providing the large clear aperture needed for applications using transmission gratings. 

The combination of long term mechanical stability and ease-of-use make GMx series mounts useful for holding and adjusting diffraction gratings in a wide variety of systems. These include OEM instruments, such as monochromators and spectrometers, as well as laboratory setups, such as the stretchers and compressors used to manipulate chirped ultrafast laser pulses.
