(1116 ) |
|
An experimental unit designed for work in degree science laboratories. The PSAW Lummer Brodhum 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 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 facilites reversal of the slides.
b) Lamp House 2 nos. On electric bulb is encased in a metal case with cord & pin, finished optical black.
