Mad City Labs – RM21™

  The RM21™ is designed as an adaptable microscopy platform which may be configured for a wide variety of microscopy techniques. The design approach to the RM21™ is unlike conventional optical microscopes. The RM21™ allows direct access to all of the optical pathway and has been engineered for precision alignment in all three axes. The RM21™ is compatible with 30mm and 60mm cage systems and is designed to be configured on a standard optical table. The RM21™ has been designed for stability and is nanopositioner ready. These attributes make the RM21™ an ideal platform for innovative instrument development and single molecule microscopy.

The RM21™ has three axes of precision motion. The objective lens holder (z-axis) is precision aligned with the optical axis of the platform and accomodates a single objective lens. The motorized lens positioner uses our proprietary intelligent control for low drift and high performance and has 50mm travel with 95nm step size. A fixed objective lens option is also available for maximum stability. Precision motion in X and Y can be achieved with manual XY micro-positioning (-MXY models) or automated XY micropositioning (-AXY models). All XY micropositioning stages travel 25mm per axis and are engineered for nanopositioning compatibility. The -AXY models employ our proprietary intelligent control. All automated axes may be ordered with optional optical encoders to provide displacement readouts.

The RM21™ is suitable for applications such as optical and magnetic tweezers, AFM integration and fluorescence microscopy. We offer a number of standard options including a TIRF Module that allows users to effortlessly shift between epifluorescence/TIRF/HILO microscopy techniques and a TIRF Lock™ to maintain the illumination angle. A wide range of customizations, such as increased ranges of motion, are also available. The RM21™ is nanopositioning ready and compatible with the Nano-Cyte® and Mad City Labs nanopositioners.
