Introduction The Oxion series has been designed with all kind of Life Sciences applications and great durability in mind. This resulted in a modern, robust and high level microscope for everyday use, equipped with excellent optical and mechanical components. Specific attention to production methods resulted also in an excellent price/performance ratio.

Phase contrast The observation of living cells and specimens with poor contrast is made possible by the use of the phase contrast method. Two different phase contrast equipments are available. All phase plan contrasts objectives can be used with both systems. A first economical way is to use sliders, each equipped with phase contrast rings.

Construction of the microscope The names of the several parts are listed below and are indicated in the picture: Photo port Revolving nosepiece for 5 objectives Microscope head Objectives Set screw for tube Object clip Stand arm Object x/y stage Stage controls Condenser with iris diaphragm Coaxial fine adjustment...
Preparing the Oxion microscope for use Handling Your microscope is a delicate product, please handle it with care. Carefully remove the items from their packing and place them on a flat, firm surface. Please do not expose the microscope to direct sun light, high temperatures, damp, dust or acute shake. Please make sure the worktable is flat and horizontal.
Assembling Steps Euromex Microscopes will always try to keep the number of assembly steps for their customers as low as possible but in some cases there are some steps to be taken. The steps mentioned below are often not necessary but described for your convenience nonetheless.
Adjusting the focusing tension The Oxion series microscope focusing knobs can be adjusted for tension. You can set it from light to heavy according your own preference. Please note that when the specimen leaves the focus plane after focusing or the stage declines itself, the tension should be set higher.
Abbe condenser Beneath the object stage an Abbe condenser (M) N.A. 12.5 is mounted. The condenser can be adjusted in height by means of a rack and pinion movement and knob (H). With this one can focus the light on the specimen by which the contrast can be optimized. The condenser is factory pre- centered if needed the following procedure can be followed to center the condensor.
2. Focus the image with the S40x objective. 3. Turn the revolving nosepiece so the S100x objective almost reaches the click-stop. 4. Put a small drop of immersion oil on the centre of the slide (always use Euromex Immersion oil).
When observing phase contrast, please set the aperture diaphragm indicator to “PH” position. Note: the phase diaphragms in the sliders are pre-centered do not need to be adjusted in operation.

Using the Zernike phase contrast set. Any Oxion model with a Zernike phase contrast set comes with the condensor and objectives already mounted and centered on your microscope. If you suspect misalignment or want to check the alignment please see the next point for ”centering the phase rings”. The height of condenser can be adjusted in height by means of a rack and pinion movement.
Using the simple polarizing set 1. Simple polarizing includes analyzer and polarizer 2. Remove the dust cover from the filter slot (M), and insert the analyzer text face up. 3. Put the polarizer into the condenser slot. 4. Rotate the polarizer to change the state of polarization. Using the 0.5x ½...
In case there is still dust visible please check if the dust is in the eyepiece by turning it. If this is the case remove the lowest lens carefully from the eyepiece and clean it. Euromex strongly recommends using Euromex cleaning accessories for your Oxion microscope It is not necessary –...
