This digital spectrophotometer is used for quantitative investigations of emission and absorption spectra and transmission curves, and for measurements related to calorimetry and chemical kinetics. Based on the Czerny-Turner principle, this device permits simultaneous, real-time recording and analysis…

Reflection grating mounted on round, concave glass carrier for demonstrating visible spectra and UV-spectra of 1st and 2nd order and, when inclined, of up to 5th order. Glass carrier: 50 mm Ø Curveature radius: 500 mm Grating: 530 lines/mm Grating dimensions: 40 mm x 30 mm

Hand spectroscope in a flat cardboard box with built-in wavelength scale for direct reading of coarse wavelengths for spectral lines and spectra. Dimensions: 180 x 115 x 25 mm

An uncomplicated yet still fully functional spectroscope for observing spectra and spectral lines. This model is made of cardboard and plastic with built-in grid. Dimensions: 145 mm x 28 mm

…attenuation. A 4 MHz transducer (U10017) is especially suitable for such measurements. An echo pattern comprising at least 3 echoes is recorded, and the spectra of the individual echoes analyzed. The result of the analysis is a shift in the average frequency toward lower frequencies, due to a stronger attenuation…

Spectral Lamps For generating line spectra of inert gases and metal vapours, with high luminance and spectral purity. Spectral lamps may only be operated in conjunction with choke 8476892 connected in series. Base: Pico 9, DIN 41539 Operating current: max.1A Operating position: upright

Franck-Hertz Experiment The quantization of energy and the generation, recording and evaluation of spectra, along with the experimental verification thereof, is included in most of the curricula used around the world. The well-known experiment first performed by Franck and Hertz in 1913 is critically…
