OPTICAL LAMPS ON STEM

Monochromatic, coherent light source for optical experiments, e.g. on diffraction, interference, and hologram reconstitution. Anodised metal housing with key switch, neutral filter for attenuating beam, 2 stand rods and power supply unit. To ... more

High temperature source designed to produce thermal radiation, for investigating how such radiation depends on the temperature and to confirm the Stefan-Boltzmann law. The tungsten filament represents a good approximation of a point source ... more

For any standard laboratory microscopes. Microscope objective for increasing beam divergence for the He-Ne laser (1003165/U21840). more

Light source with low-divergence beam for optical experiments. Black-painted metal housing on a stem, with fixture for vertical or horizontal set-up. Halogen lamp: 12 V, 15 W Connection: via 4-mm safety sockets Light aperture ... more

Ultra-bright light source for experiments utilizing an optical bench or projection. The lamp consists of a metal housing with a condenser, a movable element for axial light adjustment, a holding stem with a screw mounting, and an integrated ... more

Ultra-bright light source for experiments on optical bench and for projection. It consists of a metal housing with a condenser, a movable element for axial light adjustment and a holding stem with a screw mounting. Including plug-in power supply ... more

Red light source giving a beam with minimal divergence, housed in a compact and sturdy aluminium body. It is based on a 650 nm class II industrial laser module with a glass collimating lens. Fitted with a 10 cm stainless steel rod. A plug-in ... more

High performance 532 nm green laser (doubled NdYag). The laser (safety classification II) produces green light ideally suitable for optical demonstrations, as the wavelength is in the range where the human eye has maximum sensitivity. The visibility ... more
