Advanced Travelling Microscope 

It is an instrument for the measurement of small lengths e.g. the diameter of Newton’s rings and narrow tubes etc. It consists of a compound Microscope mounted vertically or horizontally on a right metal frame so that it can be moved in a direcon at right angles to its axis by means of a screw. The displacement of microscope is measured with verniers which moves with the microscope along a scale fixed to the instrument

Specifications:

Base: Properly painted heavy cast iron base, with two levelling screws. Top surface is machined for smooth sliding of a carriage having clamping screws for locking.
Horizontal Scale: The horizontal scale fied in the bed of the machine divided on a life me stainless steel to a length of 0 to20 cm in 0.5mm division

Vertical Scale: The vertical scale fied on the vercal pillar is also machine divided on a lifeme stainless steel to a length of 14cm graduated in 0.5mm division

Verniers: Horizontal and vercal verniers, are provided. (Both are 50 divisions, such that50 vernier scale division coincide with 49main scale division).

Sliding Carriage: Sliding carriage slides along vercal metal bar of special design which is fied on the horizontal carriage with slide on the top of the base. Fine moons screws are provided for fine adjustment both for horizontal and vercal movements. 

The Slow Moon Guide Bar: The horizontal fine moon range is especially increased to app. 3cm for convenience. In taking measurements within this range, in one operaon of the slow moon screw, without recourse to sliding adjustment of the carriage (The movement has obvious advantage for fine measurements falling with this extended range.) Vertical fine moon range is approx. 2.5cm

Microscopes: Microscopes fied on a vercal carriage can be clamped in vercal or horizontal or vercal plane of the Microscope. Eye piece is of Ramsden type and fied with fine cross line gracule. Objecve achromac with a working distance of 50mm or 75mm approximately, focusing can be done by rack & pinion.
