OPTIKA Microscopy Catalogue - Laboratory - Low ResImages are for illustrative purposes only
IM-7 represents the best of what Optika dedicates to the world of research.
This model was created to meet all the needs related to research in life science and designed to be
complemented by a series of packages dedicated to more advanced individual applications.
For all intents and purposes, IM-7 is to be considered as an inverted imaging platform, due to its
high expandability and state-of-the-art quality.
Top-level of optical equipment among our product range provides a sharp and clear view in any situation,
while top-level mechanical design offers sturdiness and long lifetime.

BRIGHTFIELD
Transmitted brightfield illumination is one of the most commonly used observation
method in optical microscopy, and is ideal for fixed, stained specimens or other
types of samples having high natural absorption of visible light.
IM-7 is fitted with high-efficiency LED brightfield illuminator, for the best
outcome when using this technique.
Capsella middle embry – Brightfield
DIC
Differential Interference Contrast (DIC) is a microscopy technique that introduces
contrast to images of specimens which have little or no contrast when observed
using brightfield microscopy. The images produced using DIC have a pseudo
3D-effect, making the technique ideal for many applications.
DIC produces high resolution images with good contrast. It is best for
observing unstained samples.
Sphagnum pores g – DIC
FLUORESCENCE
The fluorescence microscopy is the most demanding
technique in biology and biomedical sciences, as well as in
materials science.
This method is capable to study organic and inorganic
samples thanks to primary fluorescence (auto-fluorescence)
or secondary (staining and labelling with fluorochromes)
IM-7 is tailored for applications in research, clinical and
pharmaceutical diagnostic field.
Fluorescence illuminators available as mercury lamp.
Cotton fibers – UV Fluorescence
PHASE CONTRAST
Phase-contrast microscopy is a particular technique applied in transparent, non-stainable, samples like culture of living cells, microorganisms, lithographic patterns, latex dispersions, fibers, asbestos and subcellular particles.
It reveals many cellular structures that are not visible with a simple brightfield microscope.
Diatoms – Phase contrast

Revolving nosepiece for DIC and Fluorescence filter turret
The six-position nosepiece has a slot (in each of the six positions) for inserting DIC prisms.
The filter turret can hold up to six fluorescence filterblocks.
It is easily extractable, in order to facilitate the operation of inserting or replacing the filterblocks.
Mechanical stage and universal condenser
The wide 3-layer mechanical stage comes with several interchangeable plates for the use of Petri dishes, flasks and slides. The movement of the stage is controlled by a long tilting handle equipped with a pair of knobs for X/Y axes.
The universal condenser is a 6-position type, designed for brightfield, phase contrast and DIC.
Illuminator arm
The arm of the transmitted illuminator is backward tilting up to 30 degrees and it allows to use flasks and big bottles.
Main photo tube and Bertrand lens
The main photo tube located on the binocular head is easily controllable by using its control knob. 3 positions selectable:
100/0, 50/50, 0/100.
For phase contrast centering operations a Bertrand lens is available and it can be easily inserted by means of a dedicated knob.
Fluorescence equipment
A complete package of accessory dedicatd to Fluorescence technique is available as option.
