DESCRIPTION :
An experiment unit designed for work in degree science laboratories. The BESTO Lummer Brodhun Photometer assembly is assembled from the following standardized components.
a) L.B. Photometer Head:A finely made instrument with the best imported optics and now with the latest system of rigid fixing of all optical components.
Light from two sources falls on either side of a uniform white opaque screen. Thus it is reflected by side reflectors (Optical prisms) and passes through the Lumner Brodhun cube. Observing the field through a telescope, the two light intensities are compared directly. The compact Photometer head is mounted in a swivel bracket to facilitate reversal of the slides.
b) Lamp House :2 nos. On electric bulb is encased in a metal case with cord & pin, finished optical black.
