About This Product
Students sharing one instrument usually reset the eyepiece spacing for their own eyes; on this head that change does not alter tube length, so focus holds between users. The graduated scale on the condenser diaphragm shows roughly which setting suits each objective, a useful prompt when learning to balance contrast and depth of field. The cast frame with built-in handle is steady on the bench and easy to move between rooms.
Frequently Asked Questions
Does adjusting the eyepiece spacing affect focus?
No. The binocular head keeps the length of the eyepiece tubes unchanged when the interpupillary distance (50 mm to 75 mm) is adjusted, so focus is kept when users change over.
Can it be used for measurement?
An optional reticule eyepiece with 0.1 mm scales is available for measuring, but it is not included as standard.
