EMZ-5TRH: Trinocular Microscope Head + MA522: Eyepieces + FSC: Focus Block + BAS-3: Stand
EMZ-5TRH: Microscope Head
The EMZ-5TRH is a New and Improved High Eyepoint model with an eye relief of 20.9mm designed for microscopists and for people who wear glasses. It is specially designed to give the user more clearance between their eyes and the microscope. The high eyepoint models also uses a newly designed eyepiece with a wider designed lens to compliment the high eyepoint models (MA522 10X, MA818 15X, MA819 20X) Optional rubber eye guards (MA906) are also available. The EMZ-5TRH trinocular zoom body is used for photography and video applications. When the beamsplitter is engaged 100% of the light from the left optical path is directed to the phototube. The image can still be viewed through the right eyetube. The EMZ-5TRH employs Greenough optics, for improved image flatness, contrast and brightness. The EMZ-5TRH offers high resolution erect unreversed stereoscopic image. In addition to its compact design and versatility a wide variety of auxiliary lenses and stands are available to allow the user to customize their desired working distance to adapt to almost any application. Photomicrography made easy with over 300 available digital, analog and SLR camera adapters. Suitable for eyeglass users.
MA522: Eyepieces
Included is the MA522 Super Widefield Eyepiece, high eye point 10X (paired) (With 25mm reticle mount) (Fits EMZ-5H, EMZ-5TRH, EMZ-8TRH, EMZ-10H models only)
FSC: Focus Block
The FSC is an inclinable coarse and fine adjusting focus block with 5/8″ diameter mounting pin to hold the stereo microscope body onto any machine or other special applications. The 84.2mm diameter opening accepts all EM Series stereo bodies.
BAS-3: Stand
The BAS-3 Heavy Duty Boom Stand is Meiji Techno America’s most popular Ergonomic boom stand with pillar, crossarm and a 5/8” Bonder Mount socket at the end of the horizontal arm to perfectly accept industry standard focus blocks with a 5/8” bonder pin dowel. The BAS-3 is equipped with a 635mm (25”) vertical pole and a 457.2mm (18”) horizontal pole. The BAS-3 offers minimal space requirement and greatest possible amount stability for EM Series stereo systems up to 35 lbs. There is no loss of stability even at its furthest travel. The BAS-3 can swing out of the way easily, clearing the workstation for other tasks. The horizontal arm can be moved freely and smoothly left to right or can be securely locked into position with our spring-loaded handle knobs. The vertical column is used to compensate for taller specimen heights to accommodate the working distances of different microscope bodies. Anti-rotation is stabilized by a locking pin on the vertical post. The BAS-3 Heavy Duty Boom stand provides a comfortable amount of space for microscope systems that require tilt when viewing the sample at an angle. It is designed for large biological specimens to large semiconductor and electrical components. The BAS-3 is supported by a 80.00 lbs. base. This boom stand is an affordable; low cost with high quality safety features makes this boom stand unmatched value in its class. This stand has ample height and long reach to work on an inspect small to large parts under the microscope. Ergonomic flexibility, chemical resistant paint finish and corrosion resistant stainless steel columns make this boom stand an excellent choice in labs and production facilities.

FSC: Focus Block

The FSC Coarse and Fine Focus Block/Holder is an inclinable coarse and fine adjusting focus block with 5/8″ diameter mounting pin to hold the stereo microscope body onto any machine or other special applications. The 84.2mm diameter opening accepts all EM Series stereo bodies.
Focusing holders hold the microscope body and contain the mechanism that raises or lowers the body to focus on the specimen. Complete stands include their own focusing holders. But for other kinds of tasks, however, it may be necessary to mount the microscope body on a boom arm stand or directly onto a machine or some other surface. The focusing holders below offer a range of options for such applications.
