1 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 45.12 ea. 2 SPECTROSCOPE - SUPERIOR A high quality diffraction grating spectroscope for the viewing of Fraunhofer lines, flame tests in chemical analysis, absorption spectra through liquids, bright line spectra from discharge tubes, etc. The spectroscope features a large diameter eyepiece aperture, to facilitate comfortable viewing of the single, large and bright spectrum which is centrally placed in the field of view. High quality optical components ensure that absorption bands show up clearly - even weak bands that are sometimes difficult to detect. The spectrum is generated by a particularly bright transmission diffraction grating of 600 lines/mm. This robust unit is of fixed construction, with no need for adjustment, and comes supplied in a protective box. Size: 105mm long x 25mm diameter. Weight: 115g. Cat No. Description Price Per OPL-750-100 Spectroscope - Superior 83.95 ea. 3 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 81.15 ea. 4 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. Accepts our 26cm long spectral tubes. Cat No. Description Price Per OPL-820-100 Spectral Tube Unit 390.33 ea. 5 SPECTRAL TUBES A selection of high luminance spectral tubes, emitting line or band spectra of range of gases or mercury vapour. For use with the Spectral Tube Unit, OPL-820-100. Overall length of tubes is 26cm. Cat No. Description Price Per OPL-840-150 Spectral Tube Helium 75.83 ea. OPL-840-200 Spectral Tube Hydrogen 106.76 ea. OPL-840-250 Spectral Tube Mercury 102.68 ea. OPL-840-300 Spectral Tube Neon 77.75 ea. OPL-840-350 Spectral Tube Nitrogen 77.75 ea. OPL-840-400 Spectral Tube Oxygen 75.83 ea.
