There are two verniers reading up to 1 minute of arc, located 180° apart at opposite sides of the main scale. Both vernier are visible through two protective acrylic windows. Telescope Mounted on a movable pillar, the telescope has a fine adjustment screw, locking screw and axis adjustment. Achromatic objective of focal length 178 mm. Rams den eye-piece 15 X with cross-line graticule. With rack & pinion focusing. Collimator has achromatic objective of focal length 178 mm. Rack & pinion focusing. Adjustable slit, length 6 mm , is made of stainless steel.
Prism Table Marked with grooved lines to assist positioning of prism in relation to leveling screws. Has interchangeable clamping units for prism and diffraction grating. Packed in wooden case.
SPHEROMETER SINGLE DISC
SPOT REFLECTING GALVANOMETER
PHY-00686
Spot Reflecting Galvanometer finds extensive use as a D.C. null detector in wheat stone bridges and potentiometers.
Mains feed:It is a' mains' operated instrument but can operate on a 6 volt battery also. There is provision to operate this instrument can be operated on both as well as main supply 220 volts, 50Hz or 6 Volt Capacity.
Light Source:The light Source is 6 Volt and 0.3Amp bulb giving a bright spot on the scale.
Construction: The galvanometer has built in lamp and scale arrangement and housed in a bakelite case.The highly sensitive moving coil system is suspended in a taut band manner in a uniform field of permanent magnet.
Scale:The scale is 150mm long and end zero use.
Zero Adjustment: The spot of light can be set at any point on the scale with the help of zero adjusting knob.
Sensitivity Control: The sensitivity is controlled by a 2-pole,6 way switch. The switch Positions are D,1/10,1/100,1/1000 and s/c
