Research Optical Bench Lythe Type 170cm Abron

AR-1008

Digital LED with AAA Cell Operated

With Maximum and Minimum Point recording in 24 hour

With external temperature probe

It is meant for Research works. Lythe type 170 cms long. A heavy cast iron bed with a strong central rib, thoroughly seasoned and aged before machining and grinding of its upper surfaces. Total length 180 cms; with a machined full length platform for the scale. The scale is from lifetime stainless steel fitted on its machined platform on the bed. Divided in mms to a length of 170cms. Accuracy of calibration + 0.01%. Riders are provided to carry the standard experimental accessories. Under-surfaces of riders are machined true to fit the machined bed surface, and these machined surfaces are then jointly underground to give perfectly smooth sliding surfaces. Stainless venires fitted to the riders read the scale to .01 cm. The Bi-prism rider is also provided with fine cross motion read by Vernier to .01 cm.

(i) Optical Slit :With finely ground stainless jaws. Manipulation of jaw movement free from any spring control ensuring maintenance of original accuracy even after prolonged use. The following adjustments are provided for the slit and its carriage.

(a) Linear adjustment along the bed, read by Vernier to .01 cm.

(b) Fine vertical adjustment by slow motion screw.

(ii) Bi-Prism Holder : Provided with the linear adjustment and fine cross motion by micrometer screw (Vernier - .01 cm).Coarse and fine radial motion along the horizontal axis.

(iii) Micrometer Eye Piece : Provided with coarse and fine linear adjustment (Vernier = .01 cm).

Micrometer cross motion of the Eyepiece along a 30 - 0 - 30 mm scale read on a micrometer head to 0.001 cm. Micrometer head fitted with antiback-lash device

Susceptibility of Paramagnetic Solids by Gouys Method

AR-1022

We offer Apparatus for Measurement of Susceptibility of Paramagnetic Solids by Gouy’s Method in this, the solid sample in the form of a long cylinder (area of cross section A) is hung from the pan of a balance and is placed such that one end of the sample is between the pole-pieces of the magnet (field H ) and the other one is outside the field. The force exerted on the sample by the inhomogeneous magnetic field is obtained by measuring the apparent change (Δm ) in the mass of the sample. The susceptibility χ is given by χ = 2Δmg/AH2
If the sample is in the form of powder, it is filled in a long nonmagnetic tube which is then suspended from the pan of the balance.
The set up consists of the following:
(a) Scientific Balance, Capacity: 200 gms Sensitivity: 1/10 mg.
(b) Sample in the form of a long rod: Set of 4 samples, 2 each of Ebonite and Wood
(c) Electromagnet, Pieces: 75mm tappered to 25mm Mag. Field: 20KG at 6mm airgap Energising Coils: Two of approx. 13Ω each Power: 0-90Vdc, 3A, for coils in series 0-45Vdc, 6A, for coils in parallel
(d) Constant Current Power Supply, Current: 0-3A per coil Smoothly adjustable Line Regulation: 0.1% for 10% mains variation Load Regulation: 0.1% for load variation from 0 to max.Display: 3 digit, 7 segment LED display Protection: Protected against overload, short circuit and transients caused by the load inductance. Power: 220V 10%, 50Hz or 110V 10%, 60Hz as required.
(e) Gaussmeter,
The experiment is complete in all respect

Travelling Microscope Deluxe Three Motion

AR-1009b

For certain measurement it is found more convenient to provide sliding motion to the microscope tube across the stage, in addition to all other usual movements. (This microscope is very useful in Newton ’s ring experiment and graph reading etc.). A sliding carriage is fitted on the top carriage which moves at the right angle to the horizontal motion by means of rack and pinion. This motion is also graduated in millimetres having Vernier reading of 0.1 mm. Supplied in a superior quality wooden box
