QUARTZ MERCURY VAPOUR LAMP.
This lamp consists of a K.B.B. atmospheric type quartz mercury vapour burner, in a convenient housing for use as a microscope illuminant. It has a condenser which can be focussed, an iris diaphragm and screen holder. The condenser is made in glass or quartz. The back plate of the housing can be removed so that the lamp can readily be employed for other purposes. The lamp can be operated from a direct current house supply with a suitable resistance, or from alternating current with a rectifier or motor generator.
The quartz mercury vapour burner gives an illumination with a small number of monochromatic spectrum lines, and by the use of filters any one of these lines can be used giving a monochromatic source of light of great intensity. In addition to the advantages offered in the visible spectrum the burner is also one of the richest sources of ultra-violet radiation, and since quartz is transparent to rays of very short wavelength, the burner is particularly valuable to research workers requiring light in the ultra-violet and extreme ultra- violet region of the spectrum.
The housing can be supplied for existing burners. For this purpose it is necessary for the burner to be sent to us, and a small charge is made for the necessary fitting.

CORNEX MICROSCOPE ARC LAMP.
This lamp is specially suited for photography, high power dark ground illumination or for work where very deep colour filters are employed. It is supplied either with hand or clockwork feed. This latter moves the carbons at the approximate speed at which they burn away, although a slight hand adjustment may be necessary to compensate for an irregular burning of the carbons. The lamp burns on 4 to 5 amps, and on direct or alternating current. For direct current 6 m/m. and 8 m/m. carbons are used, and for alternating, 7 m/m. carbons.
A condensing lens is provided by means of which the light may be made parallel or convergent.
This lamp, with a quartz condenser, is of special use for fluorescent work in conjunction with screens or a monochromator to cut out the visible light.
