Abe, looking for the distant signatures of smaller gravitational lenses, called microlenses, is the way to go. ❋ Dave Mosher (2010)
On top of the photoresist, an additional layer with microlenses bundles the incoming light. ❋ Unknown (2010)
Pixel pitch is 4. 3µm, and gapless microlenses help boost light gathering capability. ❋ Unknown (2010)
Panasonic LX5's sensor increases the size of both layers of microlenses, decreasing the gap between lenses for adjacent pixels, and increasing light-gathering area. ❋ Unknown (2010)
The architecture of the new 16. 1MP APS-H CMOS sensor, featuring gapless microlenses with less surrounding circuitry and more sensitive, high-capacity photodiodes, also ensures that all available light is used as efficiently as possible to maximise ISO performance in low light conditions. ❋ DCT (2010)
#Some sensors approach the vignetting problem by offsetting the outer microlenses so the project the exit pupil image squarely on the photoreceptor (obviously, assuming some distance of exit pupil) - sensors designed like this would, paradoxically, show vignetting with very fast lenses with the exit pupil a long way from the sensor (typically long focus lenses). ❋ Unknown (2010)
Personally i think it's a bit far fetched to think that every single on of the 900 studied quasars have the microlensing mentioned in this article providing the same result, as i can imagine that natural occuring microlenses would all vary in their impact on the light that travels through it. ❋ Unknown (2010)
The feature that most stands out in the image above, though, is one which is actually carried over from the LX3: There are actually two layers of microlenses. ❋ Unknown (2010)
Panasonic aren't alone in this practice -- we recently reported on another dual-layer microlens from Sony -- but to our knowledge it's still a relatively uncommon design, and the diagram above is the first illustration we've seen from Panasonic showing its double-element structure for microlenses. ❋ Unknown (2010)
Reviewers such as DPR routinely test lenses for vignetting but the above results suggest that the degree of vignetting will depend on the f-number of the microlenses on the camera. ❋ Unknown (2010)
So, if the sensor silicon has a fill factor of 0.5, and we require to use f/1.4 lenses, we need microlenses of f/0.7 or lower. ❋ Unknown (2010)
DescriptionThe 15. 1-megapixel image sensor delivers ultra-detailed images and the redesigned photo diodes and microlenses of the sensor extend its light gathering capabilities to ensure improved high ISO performance and low noise. ❋ Unknown (2010)
The aim is to begin to understand the relationship between f-number and vignetting, and whether the optical theory of sensor microlenses gives us a good prediction of what people actually observe, and maybe lie to rest some preconceptions on things like telecentricity, offset microlenses and so on. ❋ Unknown (2010)
Sure, extraterrestrials could set microlenses up, but if they're capable of that feat then they're not too far from being able to send out swarms of self-replicating Bracewells. ❋ Unknown (2010)
Second, there are also now no gaps between the microlenses that sit over each 4. 7µm photosite; Canon calls them ❋ Unknown (2009)
HASO3 WSR is available in two configurations, 32x40 or 58x74 microlenses, and provides the ability to measurement wavefronts across an exceptionally wide spectral band, even with monochromatic light. ❋ Unknown (2009)
The options available for fiber coupling or the mounting of microlenses in front of the PLDs are quite interesting. ❋ Unknown (2009)
A couple of improvements from the Canon 50D's image sensor also make their way into the 5D Mark II's imager: an improvement in the per-pixel, light-sensitive area, and nearly gapless microlenses. ❋ Unknown (2009)
