1275 - Thumbnail photo showing this microscope part. Nissho Optical 209 Stereo Microscope Coarse Focus Knob - thumbnail [ 91063 ]	SERMIK_ID number under which this microscope part is placed in the database. 91063	Nissho Optical 209 Stereo Microscope Coarse Focus Knob	The name of this microscope part. Nissho Optical 209 Stereo Microscope Coarse Focus Knob	Description of this part for the microscope. Focus knob for the coarse focusing holder of the Japanese Nissho Optical 209 stereo microscope. Basic parameters of this knob Outer diameter of the knob: 45 ... mm Diameter of the knob on the focusing holder side: 28 mm Mounting on the pinion shaft: the knob has a threaded hole into which the pinion shaft is screwed, as the shaft is threaded at both ends. Once screwed in, the shaft is additionally secured with two screws Threaded hole diameter: 5 mm It is very likely that Nissho Optical (NSK for short) uses identical knobs across its whole range of stereo microscopes, or more precisely: in the head holders of those microscopes. I give the dimensions of this knob in the parameter block so that you can check compatibility if you are looking for a knob for a model other than the "209". The focusing holder of a stereo microscope contains two such knobs. Both are identical, so there is no difference between the right-hand and the left-hand knob. I offer each of these knobs separately, as a single item. The last photo shows the coarse focusing holder of the Nissho Optical 209 stereo microscope, with an arrow pointing out which knobs are meant and where they are located.

1343 - Thumbnail photo showing this microscope part. Nissho Optical 209 Stereo microscope split clamping sleeve and screw for focusing holder with 24mm pillar mount - thumbnail [ 91078 ]	SERMIK_ID number under which this microscope part is placed in the database. 91078	Nissho Optical 209 Stereo microscope split clamping sleeve and screw for focusing holder with 24mm pillar mount	The name of this microscope part. Nissho Optical 209 Stereo microscope split clamping sleeve and screw for focusing holder with 24mm pillar mount	Description of this part for the microscope. Split clamping sleeve with a screw that locks the head holder of the Japanese Nissho Optical 209 stereo microscope onto the stand pillar. This item consists of ... two parts: - aluminium clamping sleeve, split along its whole length, which is inserted into the hole in the mounting block of the head holder - screw with a three-lobe knob, driven in from the outside This clamping sleeve comes from the head holder for the Nissho Optical 209 microscope (the complete holder is available here https://www.microscopeparts.eu/part/91077). It is very likely that Nissho Optical (NSK for short) uses identical sleeves across the whole series of stereo microscope head holders it manufactured. Without this part the holder with the stereo microscope head cannot be clamped precisely at a given height on the stand. The last photo in the gallery shows the measurement of the pillar that the stereo microscope head holder is fitted onto, and in which this clamping sleeve belongs. The pillar has an unusual diameter - 24 mm - and this matters to anyone who would like to use the sleeve in other microscopes.
