Nissho Optical 209 Stereo microscope focusing holder with 50mm head collar and 24mm pillar mount - thumbnail [ 91077 ] video	SERMIK_ID number under which this microscope part is placed in the database. 91077	Nissho Optical 209 Stereo microscope focusing holder with 50mm head collar and 24mm pillar mount	The name of this microscope part. Nissho Optical 209 Stereo microscope focusing holder with 50mm head collar and 24mm pillar mount	Description of this part for the microscope. Focusing holder for the Japanese Nissho Optical 209 stereo microscope. This is a complete head holder, consisting of: - collar that the stereo microscope head ... is inserted into (in this model it is in fact the objective that goes in there) - clamping screw that holds the microscope in the collar - rack along which the microscope moves up and down inside the collar (also available separately https://www.microscopeparts.eu/part/91079) - knobs that produce this movement, that is the focusing knobs (also available separately https://www.microscopeparts.eu/part/91063) - internal shaft with a pinion that converts the rotary movement into vertical movement along the rack (also available separately https://www.microscopeparts.eu/part/91064) - mounting block with a hole for fitting it onto the stand pillar - inside the hole there is a split clamping sleeve with a screw driven in from the outside, locking the whole holder at the required height (also available separately) Basic parameters of this holder: Inner diameter of the collar: 50 mm (yes - 50 mm is not a mistake, this diameter is not commonly used on the market) Diameter of the hole for the stand pillar: 24 mm (yes - 24 mm. This is not a measuring error) Since these are unusual dimensions and you may suspect a measuring error, the gallery contains photos taken with a caliper as well as a photo of the stand pillar. The pillar is not part of this offer, but I do have it - if you need it, that is no problem :) It is very likely that Nissho Optical (NSK for short) uses identical holders across the whole series of stereo microscopes it manufactured.
