“…These areas were measured and certified by the Aperture Area Facility in the Sensor Science Division at NIST [44]. An electronic assembly containing a current-to-voltage converter circuit having a high sensitivity and a wide dynamic range [45] is mounted directly behind the photodiode to minimize noise. The circuit has a manual switchable gain setting from 10 4 V/A to 10 10 V/A (10 11 V/A for two of the photometers).…”

“…These data indicate that the photometer is linear over an output current range of 10 -10 A to 10 -4 A, corresponding to an illuminance range of 10 -2 lx to 10 4 lx. If the integration time for the signal is longer, the photometer can be used for even lower illuminance levels [50]. The linearity data also assures negligible non-linearity error in the spectral responsivity measurements.…”

PrefaceThe calibration and related measurement services of the National Institute of Standards and Technology (NIST) are intended to assist the makers and users of precision measuring instruments in achieving the highest possible levels of accuracy, quality, and productivity. NIST offers over 300 different calibrations, special tests, and measurement assurance services. These services allow customers to directly link their measurement systems to measurement systems and standards maintained by NIST. These services are offered to the public and private organizations alike. They are described in NIST Special Publication (SP) 250, NIST Calibration Services Users Guide.The Users Guide is supplemented by a number of Special Publications (designated as the "SP250 Series") that provide detailed descriptions of the important features of specific NIST calibration services. These documents provide a description of the: (1) specifications for the services; (2) design philosophy and theory; (3) NIST measurement system; (4) NIST operational procedures; (5) assessment of the measurement uncertainty including an uncertainty budget; and (6) internal quality control procedures used by NIST. These documents will present more detail than can be given in NIST calibration reports, or than is generally allowed in articles in scientific journals. In the past, NIST has published such information in a variety of ways. This series will make this type of information more readily available to the user. This document, SP250-95 (2017), NIST Photometric Calibrations, is a revision of SP250-37 (1997). It covers the calibration of standards of luminous intensity, luminous flux, illuminance, luminance, luminous exposure, and color temperature (test numbers 37010C-37070C and 37020S-37130S in SP250, NIST Calibration Services Users Guide). Inquiries concerning the technical content of this document or the specifications for these services should be directed to one of the authors or to one of the technical contacts cited in SP250.NIST welcomes suggestions on how publications such as this might be made more useful. Suggestions are also welcome concerning the need for new calibrations services, special tests, and measurement assurance programs. AbstractThe National Institute of Standards and Technology provides calibration services for submitted artifacts for luminous intensity, illuminance, color temperature, total luminous flux, luminous exposure and luminance. Additionally, the National Institute of Standards and Technology issues calibrated standards of luminous intensity, luminance, and color temperature. The procedures, equipment, and techniques used to perform these calibrations are described. Detailed estimates and procedures for determining uncertainties of the reported values are also presented along with the internal quality control procedures.

Luminous intensity measurements of sources using a new detector-based illuminance scale

1992

Until recently, the source-based photometric scale of NIST had been derived from the gold-point black-body using a long derivation chain resulting in a scale uncertainty of about 1%. In order to improve the accuracy of the photometric scale, a new detector-based illuminance scale has been realized with an uncertainty about twice as small as that of the previous source-based scale. The realization of the new illuminance scale was made by photometers calibrated for absolute spectral response, traceable to N1ST primary standard detectors using a short derivation chain. The luminous intensity scale is derived from the illuminance scale.With the introduction of the new photometric scale, the photometric calibration services of NIST will include luminous intensity and luminance calibration of different kinds of light sources, measured with standard photometers. Luminous intensity measurements of LEDs are discussed as an example to illustrate the new calibration services. In addition, the new photometric scale will allow calibration of illuminance and luminance meters with standard photometers, using different kinds of light sources.

Organic photodetectors (OPDs) for near infrared (NIR) light detection represents cutting‐edge technology for optical communication, environmental monitoring, biomedical imaging, and sensing. Herein, a series of self‐powered OPDs with high detectivity are constructed by the sequential deposition (SD) method. The dark currents (Jd) of SD devices are effectively reduced in comparison to blend casting (BC) ones due to the vertical phase segregation structure. Impressively, the Jd values of SD devices based on D18 and Y6 system is reduced to be 2.1 × 10−11 A cm−2 at 0 V, which is two orders of magnitude lower than those of the BC devices. The D* value of the SD device is superior to that of BC device under different bias voltages (0, −0.5, −1.0, and −2.0 V) due to the reduction of dark current, which originates from the fine vertical phase separation structure of the SD device. The mechanism studies shows that the vertical phase segregation structure can effectively suppress the unfavorable charge injection, thus reducing the dark current. Also, the surface energy is proven to play a key role in the photocurrent stability. In addition, the flexible OPDs demonstrate excellent performance in photoplethysmography test.
