Enjoy microsurgery

The HS ALLEGRA 50 microscope rotates cardanically around its centre of gravity, providing optimal movement with minimal force in all directions. High quality optics with a large aperture give an exceptionally bright image for the surgeon. For magnification, a 5 step changer is integrated.


Perfect vision

Apochromatic optics provide sharp and contrasty images at any magnification. The large stereo base of 25 mm results in an exceptional depth perception and 3-dimensional vision.

Standard features

Configured to work

HS ALLEGRA 50 contains a front lens of 250 mm working distance and a fix straight eyepiece head, as standard. Various front lenses up to 400 mm working distance and a 160° eyepiece head (10x) are also available. With this configuration, the microscope is also well suited for throat procedures and examinations.


Designed to move

Due to the inclination angle of -30° to +120° and the lateral tilt of +/-45°, deep cavities and narrow canals can be optimally illuminated and examined, while HS ALLEGRA 50 always remains balanced. It is an ideal tool for ENT procedures. No springs need to be tightened, no knobs turned. The mechanical brakes retain the microscope safely in its working position.

Light management

Intraoperative filter selection

The microscope contains a filter disk for daylight, softlight, UV protection (yellow filter), blue light (excitation of fluorescence), and green light (better recognition of blood vessels). In addition, two spot diaphragms are integrated to prevent glare.

Multidisciplinary use

The all-round talent

A large inclination range of -8° to +100° makes the HS ALLEGRA 50 suitable for multidisciplinary use in ophthalmology and ENT. Laryngoscopy as well as ear examinations and surgeries are possible.


Possibilities on demand

Depending on the demand, the operating microscope HS ALLEGRA 50 can be configured in a modular way. Various optional accessories are available.



Best control of the camera image and additional opportunities for observation are provided through monitors. These may be mounted directly to the microscope head to serve the surgeon and the assistant (M.DIS) or on the floor stand for other staff (C.MON HD).


Compact HD camera

C.MOR HD is a full HD colour video camera designed for the HAAG-STREIT SURGICAL microscope. Its ultra-compact camera head houses a 1/3” CMOS sensor that meets very high standards. In its 1 and 3-chip version, images are crisp and sharp. Different user settings allow individual adjustments.


Comprehensive yet intuitive recording

The prime functions of HS MIOS 5 are the recording of operation scenes as well as the capturing and recording of snapshots, together with proper identification of patient and hospital data. Images and video streams can be stored on DVD-R/-RW, HDD, USB flash drive, and external USB hard disk drive or transmitted to the hospital PACS via DICOM.

EF 5000 and EF 5001

Ergonomic control

For the best ergonomic control of the microscope, HAAG-STREIT SURGICAL recommends its corrosion-proof foot switches. While EF 5000 is connected to the floor stand via a cable, EF 5001 controls 14 functions of the microscope wireless via Bluetooth.

Floor stands

More than just carrying systems

Various floor stand options are available, including choice of illumination (halogen and LED), brakes (electromagnetic or manual) as well as size. Choose your floor stand to suit your comfort and space requirements.

FS 2-11/15

Mechanical solutions

The floor stands FS 2-11 (halogen) and FS 2-15 (LED) are equipped with mechanical brakes that allow for free-floating movements as well as for stable working positions. The light source is mounted externally for easy access. A tray to carry a camera control unit may be attached to the column. All cables are hidden inside a cable duct.


Powerful light

The floor stand is equipped with a brilliant white and clear LED illumination. In its 3rd generation, the LED features a high CRI (Colour Rendering Index) that shows colours most naturally. The homogenous light is free of hot-spot, and without IR and UV radiation is extremely safe. Its also has a highly economical lifespan of 50,000 hours.

FS 1-12

Big in small spaces

Where there is little space in the operating room or doctor's office, and for systems with few accessories, HAAG-STREIT SURGICAL offers the floor stand FS 1-12 with mechanical brakes and two 150 W halogen light bulbs with a quick switch-over mechanism.
