This is to be used with Haag Streit BQ 900 Series slit lamps (with eyepiece diameters of ~37.30 mm). This slides over the eyepiece of your slit lamp in order to increase the diameter so that the FMV Adapter can grip properly.
* This adapter ring is included in the FMV Adapter kits. Please feel free to add a second one to your order if you have multiple slit lamps.
* If you opt for an untracked shipping method, I can't be held responsible for lost parcels. I will do everything that I can to follow-up with the post office, but as I will be unable to track the delivery and locate the parcel, I will not be able to replace the item.
