Spectra Cinespot One-Degree Spotmeter

Designed for Measuring Screen Brightness

 

 


 

 


INTRODUCTION:

Spectra CineSpot Spotmeter is exclusively designed to measure screen brightness and uniformity in theaters, review rooms. CineSpot has received one of the highest awards from the Academy of Motion Picture Arts and Sciences
 

The economical, compact CineSpot 1˚ Spotmeter from SPECTRA CINE has been designed for easy use and for making simple yet accurate screen brightness measurements and other field measurements. The CineSpot features eye-level, magnified, thru-the-lens viewing of the 1-degree spot area in a large (21-degree diagonal) rectangular viewing field, with simultaneous display of the meter reading superimposed in the viewing field.

For accuracy, each individually calibrated instruments uses an ultra-stable silicon photodetector, together with computer-selected glass filters that match the spectral response of the human eye. Readability of the CineSpot extends from 0.5 to 300 foot-lamberts (30,000 footLamberts with accessory 100X Attenuator),  with excellent resolution in the critical 10 to 30 foot-lambert region.

SPECIFICATIONS:

  • MEASURING CAPABILITY: Luminance (Specify choice of units : footLamberts or candelas/sq. meter).
     

  • SENSITIVITY: Low Range, 0 to 30 footLamberts (0 to 100 cd/m2 on metric version) readings legible to 0.5 footLamberts. High Range, 0 to 300 footLamberts (0 to 1,000 cd/m2 on metric version); accessory 10X and 100X Attenuators increase upper limit to 3,000 or 30,000 footLamberts (10,000 or 100,000 cd/m2).
     

  • ANGULAR COVERAGE: The CineSpot features eye-level, magnified, thru-the-lens viewing of the 1-degree spot area in a large (21-degree diagonal) rectangular viewing field, with simultaneous display of the meter reading superimposed in the viewing field.
     

  • FOCUSING dISTANCE: Fixed- focus, 4 feet (1.2 m) to infinity; usable from 1 foot (0.3 m) to infinity.

  • VIEWING OPTICS : 1.6 X magnification, erect system with focusing eyepiece; illuminated scale for low-light readability.
     

  • PHOTODETECTOR : Ultra-stable Silicon Photovoltaic Cell.
     

  • SPECTRAL RESPONSE : Matched to the human eye response (CIE 1931 photopic luminosity function), using computer-selected glass filters.
     

  • ACCURACY : Plus or Minus 1% of full scale or 5% of reading, which ever is greater, when measuring blackbody sources; traceable to the (NIST) National Institute Of Standards Technology.
     

  • CARRYING CASE: Supplied in attractive, sturdy foam-lined protective carrying case with space for accessories.

  • warranty : One year limited warranty.
     

  • Supplied WITH:  Spectra CineSpot spotmeter are supplied with a carrying case, battery, instructional manual and warranty card.

ACCESSORIES:
 

  • Reflectance Standard Model RS-1-600
    The CineSpot can accurately measure the integrated (cosine Corrected) illuminance falling on any surface - such as screen, desktop or workbench - with the aid of the Reflectance Standard.
     

  • Neutral Density 10X Attenuator Model ND-1-600
    These calibrated, Screw-in Neutral Density Filters increase the upper measuring limit of the CineSpot. The 10X Attenuator provides a 10-times increase, while the 100X Attenuator provides a 100-times increase.
