Plancks Constant Apparatus Suppliers in China
Inside the unit are a caesium antimony cathode, a D/C power supply with a potentiometer to provide a variable retarding voltage to the photoelectric circuit and a digital display showing the retarding voltage. 6 Different coloured lenses are provided to vary the value of ‘f’. A 4mm to lead is included for connecting the picoammeter to the apparatus.
The planck's constant apparatus functions as a ready-built circuit for the measurement of the photoelectric effect.
Ideally used in conjunction with the Picoammeter.
Photocell: caesium antimony cathode (spectral response range 185-650nm)
Power source: 9V PP3 battery Dimensions: 205 x 150 x 115mm (W x H x D)
DC Stopping potential controlled by 10-turn potentiometer DC voltmeter with 0-19.99V LED display Filters: 6 narrow-band (FWHM bandwidth: 4-15nm), with wavelengths of 405nm, Female UHF socket for connection to picoammeter
