The Spectra Professional IV-A Light Meter is a compact, easy-to-use digital exposure meter with the advanced technology that makes it an essential tool for cinematographers, lighting designers, videographers and professional still photographers.


Widely considered an industry standard, the IV-A measures footcandles and lux, while instantly calculating Contrast Ratio and Averaging with storage capacity for up to 2 readings. Measurement results are displayed on an electroluminescent backlit LCD with a digital f/stop range from f/0.35 - f/128 in 1/10th stop increments and an analog bar graph range from f/0.7 - f/45 in 1/3rd stop increments. It has an exposure range of 1/8000 sec. - 3 sec., frames per second (fps) readout of 2 - 360 fps and ISO ratings from 3 - 8000 in 1/3 stop increments.

Widest Sensitivity Range Ever
Measures in f/stops from f/0.35 - f/128. Measures photographic illuminance from 0.1 - 70,000 fc and 1 - 100,000 lux
Contrast Ratio Measurement (Ratio Mode)
The ratio of two readings from 1:1 to 999:1 can be instantly calculated and displayed, thereby simplifying the set up of any lighting situation In f/stop mode the difference in f/stops between a new reading and the last memorized measurement is displayed in precise 1/10-stop increments.
Averaging
Average of two readings and/or continuous averaging in f/stop and footcandles is possible.
True Digital Design
Multiple range liner circuit is controlled by an embedded microcomputer.
Measuring System Silicon photovoltaic cell; Computer selected glass filters tailored to spectral response of the film
Measuring Modes Incident and reflected (reflected light acceptance angle is 42° square); Average, Normal, Ratio; footcandles / lux
Receptor Head Swivel head rotates 270°. Accepts optional one degree spot attachment
Aperture/Shutter Priority Shutter speed priority
Display Readout Digital LCD plus analog bar graph
Electroluminescent lamp for viewing at low light levels
ISO Range 3 - 8000 in 1/3 increments
Frames per second: 2 - 360 (for motion picture cameras)
f/Stop Display Range
Digital f/stop: f/0.35 to f/128 (in 1/10-stop increments)
Analog f/stop: f/0.7 to f/45 (in 1/3- stop increments)
Photographic illuminance: footcandles 0.1 - 70,000 and lux 1 - 100,000
Shutter Speed - Ambient 1/8000 sec. - 30 minutes
Shutter Speed - Flash No flash mode
EV Range (ISO-100) No
Cine Speeds 2 to 360 fps
Shutter angle: 45 - 205°
Exposure Memory "Memory Store" and "Memory Recall" switches: Memory Recall switch is to recall stored reading in memory-1(ml), current reading in memory-2(m2) and/or the Ratio, Average and f/stop of the two readings
Shadow/Highlight Calculation Calculates ratio of key plus fill to fill light alone from 1:1 to 999:1
