The IM-7 Inverted Microscopes Series from Optika Microscopes is a top-tier solution for advanced laboratories, available through Apex Scientific in South Africa. Specifically designed for life science research, this system combines innovation, modular expandability, and excellent imaging quality. Whether you’re performing detailed cellular observation or high-level manipulation, this inverted microscope offers the flexibility and performance you need.

 

Optical System and Head Design

The IM-7 Inverted Microscope features an infinity-corrected optical system that delivers consistently sharp, clear images. A trinocular head with a 45° inclination and a 47–78 mm interpupillary distance ensures ergonomic comfort. Furthermore, the built-in Bertrand lens improves image alignment, making this system ideal for complex research applications.

 

Versatile Photo Tubes and Eyepieces

This model provides flexible viewing options through Trino Port/Binocular settings of 100/0, 50/50, and 0/100. The PLAN WF10x eyepieces include a 25 mm high eyepoint and integrated rubber cups, offering user-friendly comfort during prolonged sessions.

 

Advanced Nosepiece and Objective Options

A sextuple ball-bearing revolving nosepiece with DIC slots in all positions supports a full range of objectives. Each lens is infinity-corrected, anti-fungus treated and offers a 60 mm parfocal distance. Users can select from multiple objective configurations to match their research goals.

 

Robust Specimen Stage

The three-layer mechanical stage, sized at 340×230 mm with a 130×85 mm movement range, uses a rack-and-pinion mechanism for precise navigation. It includes holders for Petri dishes and Terasaki plates, accommodating various experimental formats with ease.

 

Precision Focusing and Reliable Illumination

The IM-7 Inverted Microscope includes coaxial coarse and fine focus with tension control and limit stops to protect your samples. Its Koehler-type condenser offers phase contrast and a 26 mm working distance. With X-LED10 illumination, you benefit from high light output, energy efficiency, and a 65,000-hour service life.

 

Modular Upgrades for Advanced Imaging

For even more capabilities, the IM-7 can be upgraded with incident fluorescence and Differential Interference Contrast (DIC). These options transform the system into a versatile imaging platform suitable for both basic and advanced research techniques.

TechniqueDescriptionExample
BrightfieldTransmitted brightfield illumination is one of the most commonly used observation methods 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
DICDifferential 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
FluorescenceThe 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 ContrastPhase-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
