Spectra Cine SC-800 Candela PhoRad III-A Illuminance Photometer

The New Spectra PhoRad Photometer is exclusively designed for Radiologist and Radiographers for NDT/QA application and is well known for its precision, accuracy and repeatability. Spectra PhoRad Photometers are essential for quality assurance of medical imaging at Diagnostic Imaging departments in hospitals and clinics. PhoRad is very easy to use and most cost effective photometer in the industry.

This innovative, hand-held radiographic optical instrument is a completely portable, battery powered auto ranging photometer designed specifically to measure light intensity of medical diagnostic imaging displays, film viewing boxes, image monitors, collimator light field and etc. Photometer reads directly in candelas per meter squared (cd/m2) and nits as set forth in the new standards outlined in the Standard Practice for Radiographic Examination (ASTM E-1742-08). Also to optimize image contrast, it also measures the viewing room ambient background illumination falling on the viewer surface as set forth in the new standards.

Diagnostic Imaging Background
Diagnostic Imaging (Radiology) Accuracy and reliability of diagnosis in hospitals and doctors clinics greatly depend upon the conditions under which radiographs and images are viewed. These conditions include the luminance levels in candelas per meter squared (cd/m2) of the display devices (viewing boxes, image workstation monitors, image intensifier monitors) as well as the ambient room illumination (the amount of light falling on the viewing surfaces) in lux.

In an effort to reduce the rate of misdiagnosis (estimated to be as high as 30% by a number of research studies), the Federal Drug Administration, American College of Radiology (ACR), the American Cancer Society and the European community of radiologists have all adopted guidelines and standards for viewing lighting levels. In order to improve the quality of image interpretation and to reduce the chance of misdiagnosis. Spectra Cine is introducing this New Spectra PhoRad Photometer and it could easily provide radiology departments with a hand-held photometer that measures both display device luminance and ambient light (illuminance).

Spectra PhoRad Photometer measures light output of illuminator to ensure that user is in compliance withASTM E-1742-08 and ACR-recommended light levels. Readings are in nits or candelas per meter squared (cd/m2) or foot Lamberts (fl). A second Cosine Corrected Diffuser to measure the Ambient light in lux (lx) or foot-candles (fc). This instrument is essential for quality assurance of medical imaging at Diagnostic Imaging departments in hospitals and clinics.

Type
Spectra PhoRad Illuminance Photometer is a completely portable hand-held, battery powered auto ranging photometer for measuring ambient light in lux (lx) with the cosine corrected photodisc.

Photopic Response
Ultra-stable silicon photodiode, together with computer selected glass filters to match the spectral response of the human eye (the CIE 1931 photopic response function) V (Lambda) filter.

Calibration
Calibration is traceable to the National Institute of Standard Technology (NIST), Washington D.C. Certified for one year.
