Abstract
Reflectometer for measuring the optical reflecting power of specimens by comparative measurement between the reflecting power of a reference object and the specimen to be measured. In order to keep low the supply of power to the light source required for this purpose, use is made of a pulse discharge tube (T) whose flash discharge is produced by the discharging of a capacitor (C2). A time-delay circuit leaves the digital display device which displays the measured values switched on only for a short, but adequate, read-off time. The power consumption of the reflectometer is reduced by the fact that a small storage battery suffices as voltage source, and the reflectometer therefore has a low weight, which enables it to be carried. <IMAGE>
