Minolta NT-1/3P Luminance Meter
A high-performance Specialized light meter for professional or scientific use. Its focusing single lens reflex viewfinders vises a clear, bright, magnified circular view covering 9 degrees with a clearly marked 1 or 1/3 center spot. Simply pulling the measuring trigger instantly measures only the light in the spot. With no influence from surrounding areas. Luminance values are indicated through the finder by direct LED digital readout or may be recorded in graph form by use of a convienent output jack on the side of the unit. The highly sensitive silicon photo Cell and electric circuit yield high accuracy over a wide range.

Features:
- Flareless optical system
- The luminance meters flareless optical system, which includes a focusing objective lens and total reflection mirror, ensures the meters photo cell will measure only the light within the 1 or 1/3 reading spot with no influence from surrounding areas.
- Sillicon photo cell receportor
- The stable resonse and extra sensitivity of the silicon photo cell enables the Luminance meter to make readings withing +2 precent of the CIE Relative photopic luminosity cureve.
- LED Digital ft-L or cd/m2 Indication in the finder
- Light-emitting diodes in the viewfinder indicate precise fot-lambert or andelas pre square meter reading with greater repeatability than meters with analog-type readout
- Compact lightweight body
- Besides its simple controls, the luminance meters small size and comfortable handgrip make it one of the easiest to use meters of this type on the market.
- Versatile operation
- analog output jack for continous recording of luminance
- convenient Tripod Socket
- Viewfinder indication blinks as over-range indication
- display does not light when battery power is insufficient
