دستگاه آزمایش فوتو الکتریسیته (Compact arrangement for determining Plank's constant)
Model 330401
Modern Experiments Equipment
Complete assembly of optical elements and a socket for the photoelectric cell. With a removable cover aperture for the entry of light from the high pressure mercury lamp and an observation window behind the photoelectric cell which stays closed during measurement to prevent interference from extraneous light sources
The ray path is deflected by mirrors, so that the assembly can be kept short. Lenses (1 capacitor, 2 image lenses), slit, rectangular diaphragm And direct – vision prism in holders on a clamp rider mounted on 2 rails. One of the rails can be swiveled by means of a threaded guide such that the – photoelectric cell is led through the individual spectral lines. With a shielded cable for connecting the amplifier
Window for light entry : 3.5 m dia
Distance between light – entry window and photoelectric cell : 1 Cm approx
Dimensions : 68 Cm × ۳۶ Cm × ۲۳ Cm
