4.3 Optical specifications of the BioBlue range
The EUROMEX BioBlue range microscopes are standard equipped with 1 or 2 widefield
eyepieces WF10x (O) and semi-plan-objectives, as mentioned below in table 1.
Mono
Bino Optical specificitions, and object stage type:
BB.4200 SMP4x, SMP10x, SMPS40x
– Straight stage with 2 object clips
BB.4220 SMP4x, SMP10x, SMPS40x
– Coaxial mechanical stage
BB.4240 SMP4x, SMP10x, SMPS60x
– Coaxial mechanical stage
BB.4250 SMP4x, SMP10x, SMPS100x
– Coaxial mechanical stage
BB.4260 SMP4x, SMP10x, SMPS100x
– Coaxial mechanical stage
Table 1
The S40x and S100x objectives are equipped with a spring mount, to prevent damage to the
frontlens and the slide.
The Numeric Aperture - N.A.
– of the objective is an indication for the resolving power of the
objective.
The total magnification can be calculated by multiplying the magnification of the eyepiece with the
magnification of the objective. The magnifications are displayed in the table below:
Eyepiece
Objective Magnification
10x 4x 40x
10x 10x 100x
10x 40x 400x
10x 60x 600x
10x 100x 1000x
4.4 Object stage
On the BB.4200 the slide is placed beneath the object clips. On the other models into the clamp of
the mechanical stage (G) and can be carefully moved into X- and Y- directions. Focusing the
specimen is done by using the coaxial coarse- and fine adjustment knobs (I).
4.5 Coarse- and fine adjustment
The coarse- and fine adjustment knobs (I) for the height adjustment of the object stage are
mounted together on one (1) axle (co-axial). On both fine adjustment knobs there is a graduation
with intervals of 0.002 mm. This can be used to measure depths in a specimen.
4.6 Abbe condenser with iris diaphragm
Beneath the object stage an Abbe condenser (M) N.A. 12.5 is mounted. The condenser can be
adjusted in height by means of turning. With this one can focus the light on the specimen by
which the contrast can be optimised. The condenser is factory pre-centered.
The iris diaphragm with filter holder is mounted beneath the condenser. The light intensity can be
adjusted by changing the flexible opening.
