Pharmaceutical Photostability and Stabilization Technology
For instrumentation without a built-in sensor, calibration can be performed
manually using a UV filter radiometer, luxmeter, thermopile or chemical
actinometer (18–20). With the exception of the thermopile, all of these devices
suffer from the ...

To this end, light intensity of a lamp is measured by a luxmeter. This value needs
to be compared with the lightradiation that is influenced by aerosol clouds. A
closed, light transmissible vessel which is filled with aerosol cloud has to be
placed ...

New method of angular correction of a luxmeter photometric head Abstract. A
model of a new kind of luxmeter photometric head is designed. The luxmeter
photometric head fitted with a new kind of element for spatial (angular) correction
has a ...

The spectral sensitivity characteristics of the luxmeter and radiometer are also
different. Therefore, the light-shielding characteristic, given in the radiometer
documentation, may not correspond to its value under actual measurement
conditions ...

ON THE QUALITY OF TYPE YU-16 LUXMETERS.
To improve the quality of luxmeters of Type Yu-16, the following must be accomplished: (1) the quality of the selenium photo-elements must be greatly improved, and only photo-elements that have naturally aged over a period of 6-12 months ...

Photocells for internal photo-effects Some crystals change their electric
resistance, when they are hit by light, and absorb photons. This effect is, as is
explained earlier in ...

Lighting Technique: General Course
A GOI (State Optical Institute) or objective luxmeter is used to measure the
illumination in a room. The results of the measurements are to be drawn up into a
table, equal illumination or isolux curves being drawn. The uniformity of
illumination ...

In other words, counting such photons corresponds to the measurement of the
illuminance. This is reflected in the 'toolbox', that is used by practical
photometrists: its main tool is the device to measure illuminances – for short, the
luxmeter ...

The Right Light: Matching Technologies to Needs and Applications
Illuminance is measured by photometers (Figure 1.16) that convert light into
electricity (luxmeter). Ε = Φ/Α = Ι/r2 Where Ι is the luminous intensity and Α is the
area of incidence. FIGURE 1.16 A commercial luxmeter. Luminance, L, with the
unit.
For this purpose first the diaphragms (Figure 1 5) were removed and the
illuminance caused by a light source behind an interference filter (1 = 520 nm)
was measured using a linearized luxmeter. (The interference filter was used to
leave the ...
