HEINE OMEGA 500 Binocular Indirect Ophthalmoscope



How do I change the light source in my HEINE OMEGA500?

First allow the instrument to cool down. Disconnect the instrument from the power source. Unscrew the control so that the optics unit is free to move. Slide the bulb cover upwards. Do not pull on the cord. Swivel the optics unit to enable the bulb to be pulled out of the bulbholder. Clean the glass dome of the new bulb carefully with a soft cloth. Insert the new bulb so that the locating pin on the bulb body fits into the guide in the bulbholder. Re-fit the bulb cover into the optics unit and slide the bulb cover back down into position.


General


Which power source is compatible with my HEINE OMEGA 500?

The HEINE OMEGA 500 can be used with the belt-worn HEINE mPack (8.5 hours opeating time) or with the cable-free HEINE mPack UNPLUGGED (3.5 hours operating time).


I cannot decide between LED or XHL iIlumination. What is the difference?

This is a matter of personal taste. If the user has a stronger focus on the best CRI for their examination, XHL illumination would be the preferred option. Advantages of LED are longer operating time and battery life as well as the fact that there is no need to ever change bulbs.


How can the optical system be adjusted for better observation of undilated pupils?

By moving the adjustment lever you can change the angle of illumination (parallax) and the line of sight for each pupil (convergence) to gain fully illuminated, stereoscopic views, not just through fully dilated pupils but also through pupils as small as 1mm in diameter.


The HEINE OMEGA 500 is marketed as dust proof. Why do I still see dust when looking through the front glass of the indirect ophthalmoscope?

The term dust proof means that the instrument is protected against the infiltration of dust. The instruments have no open and unprotected windows. Nevertheless, in the unlikely case that some dust particles get encased inside the instrument in a heavy use environment, the product can be serviced by HEINE. Microparticles that can be seen through the instrument are normal and don’ t obstruct examination.


What does the HEINE HC50 L Headband Rheostat do?

The Rheostat can be conveniently mounted on the left- or right-hand side of the headband and controls LED or XHL illumination. Light-intensity can be precisely adjusted – especially in the low-light intensity range. It also operates as an on/off switch.


Can I upgrade from an XHL to an LED version?

Yes, the OMEGA 500 can be easily and quickly converted with the help of an upgrade kit. The upgrade kit includes the LED unit plus the HC50 L Rheostat.
