The sensor combines a broadband visible plus infrared (IR) photodiode, an IR-responding photodiode, and a photopic
IR-blocking filter on a single CMOS integrated circuit.
LKC's patentedRET eval Complete Option includes 30 Hz Flicker ERG using LKC's Sensor Strip Skin Electrodes (patent-pending), as well as ISCEV-compliant 5 and 6 step protocols, custom protocols, flash VEP, photopic
negative response, s-cone, real-time pupillometry (patented), the ability to test with or without dilation, and other innovative features unique in a lightweight, handheld device at an accessible price point for clinicians.
For example, if the client wants staff to see fine spatial detail, high photopic
illuminance levels are needed on the task to process the visual information quickly and accurately.
No significant differences in contrast sensitivity between groups at the photopic
level were noted, but contrast sensitivity values were significantly lower for three and six cycles per degree in the LASEK group at the mesopic level.
BX-1 design includes fully multicoated lenses for enhanced photopic
transmission and bright, crisp images.
These studies have tended to find that SPD affects spatial brightness and that this is not predicted by quantities derived from V([gamma]), the CIE Standard Photopic
Observer, such as illuminance and luminance.
The aesthetics of cool fluorescents at nighttime are suboptimal, and while the energy savings potential of so-called scotopic lighting is demonstrable, lighting designers must currently still design to IESNA-established lighting criteria and recommendations, which are all based on the photopic
luminous efficiency function V(lambda) (IESNA 2010, U.
Walks on the courses were made under two illumination conditions: photopic
It causes significant thinning of the outer plexiform layer, lowering of the horizontal cell count, and significant reduction in amplitude of photopic
and scotopic electroretinographies.
The relation of apparent brightness to contrast threshold on a photopic
background: Dependence on retinal position and size.
It depends among other things on target size and ambient light level, decreasing with increase of light level, but leveling off and hardly changing in the photopic
spectral sensitivity of domestic ducks and turkeys was determined using an operant psychophysical technique.
