Photocell for h-determination
Article No: 06779-00
The photocell is used to investigate the photoelectric effect and for the experimental determination of Planck’s constant.The vacuum-sealed photocell is safely housed in a plastic enclosure and equipped with a removable metal cover. Robust and stable construction for precise laboratory experiments Three-position shutter: circular aperture, entrance slit, or closed, allowing flexible light control Aperture tube for the secure insertion of interference filters Housing base with holding magnets and a 6 mm threaded hole for easy mounting on the supplied support rod Technical Specification 4 mm connection sockets Diameter of active area: 15 mm Wavelength range: 185–650 nm Maximum sensitivity at: 340 nm Cathode material: Cs-Sb Anode material: K-Sb-Cs Sensitivity: 110 µA/lm or 70 mA/W Maximum cathode current: 6 µA Maximum voltage: 100 V Operating voltage: 15 V Dark current at 15 V: 2.0 pA Cell capacitance: 2 pF
