Flexion Twin Lite

The New Essential

Flexion twin lite Blue & White

The New Essential. Indispensable.

Say hello to our newest member of the Flexion microscope family. Like its family members, the new Twin lite has been designed and developed through a consistent focus on the needs of dentists. As with the Twin, there are two models to choose from: the fluorescence Blue model or the light champion White. Both feature the all-important Natural Light Filter, which extends the preparation time for composite materials. The Twin lite deliberately does without the extensive selective filter system including the polarizing filter of its big Twin brother making it an ideal tool for general dentists and dental hygienists.

The Power of Two

Two LED lights ensure an outstanding microscopy experience.

Blue & White

A class of its own.

The name “Twin” indicates that both models are equipped with two LED light sources. While the Twin lite Blue uses its fluorescent light to represent the normally invisible boundaries and transitions between tooth material and fillings, the Twin lite White has the full power of two LEDs that penetrate even into the deepest root canals.

Twin lite Blue

Visibility through Fluorescence

In addition to the white LED, the Flexion twin lite Blue is equipped with a second LED (dark blue), which improves the identification of restoration materials, tartar and caries. The UV light causes porphyrins inside the caries bacteria to fluorescence orange/red. The fluorescence mode is set using an ergo-nomically placed wheel with the right hand.

Twin lite White

Light Boost with up to 200.000 Lux

The white version of the Flexion Twin lite takes account of the wish of many dentists for a particularly well-lit treatment area by providing a second, white LED for additional luminosity. With the Twin lite White, the enormous power of up to 200.00 Lux of the two LED lights is visible. Both LEDs can be switched independently of one another to identify structures in the root canal.

Natural Light Filter

The Natural Light Filter extends the preparation time for composite materials. The rendering is closer to real warm light than the Orange Filter. Improved visibility for passages between hard and soft tissues.

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 twin microscopes 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 5.500 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 twin 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.


Whether you prefer to document the treatment in 4K, in HD or with a smartphone: Focal lengths and optics
have been uniquely designed for an ideal match to today’s latest digital cameras.

Direct power supply for the camera from the microscope



MicroVis – Our documentation software saves time for the important things

With the MicroVis software specially developed for the Flexion microscopes, the image and video files of the treatment are conveniently and securely stored in your patient‘s file (PACS). Thanks to its user-friendliness, MicroVis relieves your team and you save important time. MicroVis is optionally available and compatible with all common practice management systems.

Mounting Options

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).
