As can be seen in Figure 12, only a small portion of the spectrum is removed in transmission, providing a high see-through photopic transmission.
Caption: The planetarium app Sky Guide for iOS devices incorporates several all-sky survey mosaics into the appearance, including coauthor Nick Risinger's own Photopic Sky Survey (left).
Another aspect of the waveform produced is the photopic negative response (PhNR), which is shown in Figure 5 (page 71); this is produced due to ganglion cell activity but is not routinely assessed as part of the ISCEV standardised protocol.

In retinal detachments the scotopic ERG is generally more disturbed than photopic ERG; both are more disturbed than would be expected from visible detached retina.

BX-1 design includes fully multicoated lenses for enhanced photopic transmission and bright, crisp images.
Human melatonin regulation is not mediated by the three cone photopic visual system.
Any spectral mismatch error of the photopic sensor is compensated on-line using the diode array's measured spectral data.
In addition, these devices became very proficient in photopic sensing, which is the ability of silicon photodiodes to sense light in a way which emulates the human eye.
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.
