Summary

The RZDT combines Meiji's CMO type zoom stereo body with binocular head and brightfield / darkfield stand with 6V 30 W halogen illumination for a research stereo microscope of exacting quality. Choose eyepieces and an objective to suit your application.

RZ-B Microscope Body

The RZ-B is the central component of any RZ system. The zoom optics have a 10:1 zoom ratio and a base zoom magnification of 7.5x to 75x with a 1.0x main objective. Depending on your selection of eyepieces and objectives, this translates into an total magnification range of 3.75x to 300x. The zoom controls indicate magnification at 12 positive click-stops throughout the zoom range, making photograph framing and measuring easily repeatable and consistent.

Dual-iris diaphragms offer excellent control over resolution, contrast, and depth of field. The zoom optics are housed in a rugged aluminum alloy body for increased stability and durability, and all components are coated with an anti-static finish to protect sensitive specimens.

Choose from one of five plan achromat objective lenses: 0.5x, 0.75x, 1.0x, 1.5x or 2.0x.

Viewing Head

There are two types of viewing head. MA748 standard binocular head is inclined 45° with an interpupillary adjustment range of 46mm-75mm. Alternatively, MA749 Ergonomic head offers adjustable viewing angles through 10°-50°, also with 52mm-75mm interpupillary adjustment.

Choose two eyepieces from a selection of Ultra Widefield eyepieces: 10x/FN24, 15x/FN16 or 20x/FN12 all with reticle mounts. All eyepieces are high eyepoint and focusable. Please call for optional reticles.

Stand

The RZDT transmitted light stand is for brightfield and darkfield illumination. Front-mounted slider allows quick transition between brightfield and darkfield observation. The RZDT features a 6V 30W halogen lamp with variable intensity control, built-in power supply for optional COX illuminator, aluminum alloy base, anti-static finish, safety collar, 94.5mm diameter clear glass stage plate, and two stage clips.

Note: Optional 6V 30W transformer (MA651), and 1/4 wave plate (MA762) are both required for use with optional COX vertical illuminator.
