Nucleus® MKR fluorescence microscope cores
About This Series
MKR microscope cores consist of a motorized filter cube turret, linear motor focus stage and objective mounting bracket. They use an innovative magnetic counterbalance to offset the moving mass of the focus stage, leaving the full thrust available to provide lightning fast focus steps. A magnetic quick-change objective system allows manual objective changes in seconds and supports any objective thread.
MKR microscopes cores are compatible with X-MOR-E motorized objective turrets and HL04 IR laser autofocus sensors.
An optional MJB junction block (sold separately) introduces an additional optical path between the X-FCR filter cube turret and the objective lens. In order to accommodate the MJB25, the MKR025B raises the objective by 35 mm relative to its standard location. The additional distance between the objective lens and tube lens may result in vignetting (reduced intensity near the periphery of the image) when high N.A. (0.80 or greater) objective lenses are used.
As part of Zaber’s modular microscope platform, these microscope cores can be combined with different XY stages, camera tubes, illuminators and frame brackets to build up complete high performance automated microscopes. Our easy to use Microscope Configurator can walk you through the process of selecting the right modules and functionality for your application.
- Frictionless magnetic counterbalance offsets moving mass of focus stage.
- Multiple sets of mounting features and a reconfigurable counterbalance allow MKR cores to be used in both upright and inverted microscope applications.
- Epi-Illuminator port accepts Zaber MLR3 illuminators or custom optics using an SM1 standard lens tube.
- Camera tube port accepts Zaber MTC90 camera tubes.
- 25 mm of focus stage travel provides plenty of room for objective changes without risking damage to the sample or objective lens.
- 20 nm focus step size
