Biological microscopes

Novex B series The attractively priced Novex B series microscopes are high quality, robust biological microscopes for educational purposes and scientific research. Viewing Head and Eyepieces The microscopes of the Novex B-series are available in three configurations: monocular, binocular or trinocular. The viewing head is mounted at 30° angle and can be rotated though 360°. Supplied with a WF 10x eyepiece(s). These microscopes have a coaxial course and fine focus adjustment. Revolving Objective Changer All models are equipped with a reversed quadruple revolving objective changer with ball bearings...

Darkfield Illumination The darkfield set consists of a special condenser with a large numerical aperture N.A. 1.20 (86.627), a DIN Plan 100x objective with iris diaphragm (86.521) and a cold-light source (LE.5210 or LE.5211) with a flexible light guide (LE.5241). This indirect illumination method enables the microscope user to view the contour and structure of transparent and low contrast specimens on a dark background. leptocytosis of red blood cells with bright field leptocytosis of red blood cells with dark field One example of the use for this darkfield technique is living blood analysis...

Top class research microscopes Bright field Phase contrast The phase contrast method was designed in 1934 by the Dutchman Frits Zernike to observe very thin or transparent objects. This technique uses the fact that light travelling through tissue undergoes a phase shift due to diffraction. By recombining the phase shifted light with the background light, a contrasted image appears in the eyepiece. For phase contrast an objective with a retardation plate and a condenser with a phase-ring is used. Temperature controlled Stage Besides a phase set the models 86.525 and 86.541 have a specifically...
