1 SPECTROSCOPE - BASIC Uses a CD or DVD as a reflective diffraction grating and clearly shows Fraunhofer lines in the spectrum arising from natural light - and distinctive emission bands from artificial sources such as sodium lamps. Differences between fluorescent lighting tubes - e.g., white light or ‘warm’ light types - can be easily identified by their distinctive emission bands. The spectroscope is made from virtually indestructible polypropylene and supplied in flat pack form - taking about 30 seconds to assemble. It comes with a free CD but can be used with any CD (or a DVD for higher resolution). Cat No. Description Price Per OPL-800-100 Spectroscope - Basic 5.29 ea. 2 SPECTROSCOPE - STANDARD For the rapid qualitative examination of composition of emission and absorption spectra. Comprises a plated brass pipe with adjustable slit, drawtube and multi-element prism. Supplied com- plete in a lined wooden case. Cat No. Description Price Per OPL-700-100 Spectroscope - Standard 41.02 ea. 3 SPECTROSCOPE - SUPERIOR Linear spectrum is generated by a particularly bright transmission diffraction grating of 600 lines/mm. The unit is of fixed construction - no need for adjustment. Supplied in protective rigid box. Size: 25mm dia. x 105mm long. Cat No. Description Price Per OPL-750-100 Spectroscope - Superior 66.92 ea. 4 LASCELLS SPECTRAL SOURCE This unique unit has been specially developed to provide a varied range of light sources for examination by spectrometers. The apparatus includes various monochromatic LEDs, together with a full set of transmission filters which can be used with the tungsten filament lamp. Compare yellow filter with yellow LED; examine the wavelength distribution from a white LED; compare clear envelope and red envelope LEDs; examine the band spectrum from a tungsten filament at vari- ous levels of brightness etc. Requires a 12V d.c. power supply - connection via 4mm leads or a 2.1mm centre positive jack plug plug top adapter. Cat No. Description Price Per OPL-565-100 Spectral Source 71.03 ea. 5 SPECTRAL TUBE UNIT A 230v unit made from black painted steel. The integrated current limiter ensures a long service life of the tubes. Spring- contacts in fully insulated fixtures guarantee secure mounting and reliable operation. Voltage: 5000 V. Maximum current: 10 mA. Dimensions: 370 x 120 x 90mm. Conforms to all safety regulations for electri- cal measuring, control, monitoring and laboratory equipment, as specified under DIN EN 61010, Section 1, and the equipment has been designed to meet protection class I. Cat No. Description Price Per OPL-820-100 Spectral Tube Unit 340.38 ea. 6 SPECTRAL TUBES High luminance spectral tubes emitting the line or band spectrum of a gas or mercury vapour. Cat No. Description Price Per OPL-840-150 Spectral Tube Helium 62.57 ea. OPL-840-200 Spectral Tube Hydrogen 89.40 ea. OPL-840-250 Spectral Tube Mercury 85.41 ea. OPL-840-300 Spectral Tube Neon 64.56 ea. OPL-840-350 Spectral Tube Nitrogen 64.56 ea. OPL-840-400 Spectral Tube Oxygen 62.57 ea.
