I INTRODUCTION
·
The ISO-TECH LUX-1335 digital light meter is a precision
instrument used to
footcandle）.
·
It meets CIE photopic spectral response.
·
It is fully cosine corrected for the angular incidence of light.
·
The meter is a compact, tough and easy to use instrument.
·
The light sensitive component used in the meter is a very
stable, long-life silicon photodiode and spectral response filter.
