HS ALLEGRA 300 is optimized for oral cavity and plastic reconstructive procedures. With the support of two ergonomic handles the microscope rotates cardanically around its center of gravity, thus providing optimal movement in all directions. This construction keeps the microscope permanently in balance.

The microscope‘s large stereo base of 25 mm results in an exceptional depth perception. The optics provides high color fidelity, strong contrast, and high resolution.

Factory-preadjusted mechanical soft-glide brakes allow extremely high movability of the microscope and safe stability in the working position. The HS ALLEGRA 300 contains a 1:6 zoom and a fine focus adjustment.


Movability, light & accessories

For better access of the assistant on the left, the microscope arm is mounted at the right side. The inclination angles of -55° to +95° and the lateral tilt of 45° provide optimal illumination for recognition of deep cavities and small canals.

The inclinable 160° eyepiece head can be mounted to the VERTISCOPE, a 60° adapter, to allow extreme retrograde viewing. This adapter contains a rotatable ring to move the oculars into a horizontal position even when the microscope is tilted sideways.

For coobservation the high-resolution monitor M.DIS can be mounted to the microscope arm, where it will not affect the balance. M.DIS allows intraoperative viewing and controlling of video recordings and snapshots.

Optionally, an integrated video camera (1 CCD) can be delivered. This reduces the length of the microscope and makes cleaning easier. Attachments for small digital cameras are also available.


HS ALLEGRA 300 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 against glare.

An additional UV filter may be switched in to protect the surgeon’s eyes during UV hardening of filling material.


MIOS stands for Microscope Imaging and Operation System. Its prime functions are recording of operation scenes, capturing and recording of snapshots, together with proper identification of patients’ 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.


C.MOR HD is a full HD color 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. With a resolution of 900 TV lines and an S/N ratio of 500 dB images are crisp and sharp. Different user settings allow for individual adjustments.


With its flat design and the size of 21.5“ the brilliant HD monitor C.MON HD can easily be attached to the microscope‘s floor stand. Its touch function can be operated even with medical gloves. Due to the planar screen and glass surface it can be disinfected easily. For the safety of the system C.MON HD is fully approved for medical use.
