Optics – For superior results

Advanced Optical Design

CJ-Optik Flexion microscopes are highly acclaimed for their superior image quality. It is only through CJ-Optik working closely with the optics designer that the optimal specifications can be developed. With the use of apochromatic optics in the Flexion Advanced microscope dentists can detect the finest colour and structure details.

Perfect Illumination

The fanless LED spot lighting provides a well-lit treatment area with high colour rendering index and 5.400 K. Future-proof with 65,000 hours lifespan. The spot diaphragm always shows the assistant the exact treatment site and prevents light from falling into the patient‘s eyes.


Choose from either the VarioFocus2 with 200 – 350 mm range or the VarioFocus3 with 210 – 470 mm working distance and plan-apochromatic correct built-in optics. The superior light transmission provides optimal viewing and documentation results. Removable protection cover lens with Hydrophobic Coating (HPC). Index Matching Coating for highest transmission and low reflection rates.

Details make the Difference

Just to name some of the many remarkable features that makes working with the Flexion Advanced microscopes
so comfortable:

Ergonomics – For stress-free treatments


Anyone who has ever worked with one of our microscopes knows why we called them Flexion. We consider the Flexion as a flexible extension of the dentist’s eyes. The dentist‘s upright treatment position ensures a relaxed posture and thus prevents neck and back problems in the long term.


The uniquely designed MonoGlobe is the weightless movement balancing system. The coupling system allows fluid and smooth repositioning at all angles without having to adjust the tension.

Quality at the Touch of a Button

Ergonomically placed controls ensure that all functions are immediately at your fingertips for all inter-procedure changes.

Cable Management

HDMI, USB, camera AC/DC power and 24V monitor power supply are integrated within the arm for a cleaner cable management. USB, HDMI, Medical monitor power integrated for a better workflow. No fragile fibre-optic cables that break or tangle.

Flexible and customized

Flexion – The name says it all, even with the different mounting options. In addition to the dimensions shown here, CJ-Optik also offers tailor-made heights and lengths of all tripod parts in order to adapt the assembly to the premises in the best possible way. In addition, the parts can be interchanged (e.g. when changing from floor to ceiling mounting).

Mobile Stand

Floor Mount

Ideal for use in multiple rooms.

The space-saving alternative to the mobile stand.

Ceiling Mount

Wall Mount

Maintains ground clearance. Pillar height can be adjusted to any ceiling height.

The alternative to ceiling mounting.

We recommend a working position in which the suspension arm is at a right angle and the microscope head is at a distance of one meter from the vertical column (as shown above).
