Versatility in illumination and stand options

Brunel BMZ Stereomicroscopes

The BMZ range of trinocular stereomicroscopes represents a modular approach in a series of instruments offering quality optical performance with versatility in illumination and stand options. Designed and constructed in a style comparable to the market leaders, the BMZ represents a modern approach at an extremely competitive price. The long arm versions incorporate a range of stand versions.

The zoom ratio of the BMZ is 1:7 and the objective zoom range is x0.65 to x4.5. Giving a magnification range of x6.5 to x45 which can be extended with additional eyepieces and auxiliary objective lenses to x4.9 to x225. However the working distance will decrease with the use of auxiliary lenses as shown in the tables below.The useable working distance remains constant  irrespective of the position of the zoom control. The interpupillary distance adjustment range is 55mm to 75mm. A wide range of accessories is available for this excellent stereomicroscope.
