Minus K Technology

Laser Interferometer Vibration Isolation Minus K Technology has announced an ultra low natural frequency negative stiffness optical table isolation system for Raman spectroscopy, atomic force microscopy (AFM) and AFM Raman integration. The MK52 achieves 0.5 Hz or lower vertical and horizontal natural frequencies and supports static loads. When adjusted to a (0.5-Hz natural frequency, it achieves 93% isolation efficiency at 2 Hz. 99% at 5 Hz and 99.7% at 10 Hz. Available in sizes up to 4 x 8 ft with gross load capacities up to 2000 1b, it has a 3/16 in.-thick ferromagnetic stainless steel top skin, 3/16 in.-thick carbon steel bottom skin and a plated-steel honeycomb core, it is suitable for ceil injection, confocal and optical microscopy, water probing and laser applications in medical research.
