Ophthalmometer Haag-Streit OM 900, pre-owned
Description
Pre-owned Ophthalmometer Haag-Streit OM 900
Colour: grey
Fine condition
Inclusive 1 year full Schairer-warranty
The Haag-Streit OM 900 Ophthalmometer uses a classical distanceindependent measuring principle which meets the three requirements of Helmholtz:
1. The size of the mire image is independent of the distance between the Ophthalmometer
and the measured object.
2. The resulting measurements are independent of the distance between the Ophthalmometer
and the measured object.
3. The measurements are independent of the quality of focussing and are not negatively
affected by the accommodation of the user.
It meets the latest IEC 601-1 norms
Two different test patterns Javal or Cross mark
can be used, switching from one to the other easily
with just the touch of a lever.
The following measurements are possible with the OM 900:
Central corneal radii
Achoice of sagittal radii either in 20°, 25° or 30°
Meridional radii in 30°
The integrated software calculates and
displays the following:
Central corneal astigmatismus
Sagittal radii
Meridional radii
Eccentricities
The difference between the eccentricities of
sagittal radii and meridional radii in 30º
All of which can be transferred to a printer or PC
(both optional extras)
User Calibration
The OM 900 can be user-specifically calibrated,
thus eliminating subjective systematic measuring
errors.
Easy User:
Up-to-date design allows measurement setting at
the ocular and measurement values to be given at
the press of a button.
