Beware field curvature, color fringing
. Zeiss's LotuTec, Bushnell's RainGuard and other water-shedding treatments clear the view in wet weather.
The gentle, rounded bokeh generated when point light sources are blurred exhibits very little color fringing
and remains pleasing all the way to the edges of the frame, enabling expression of a dreamy ambiance.
While it's not uncommon for an ED refractor to display a little color fringing
on a bright star that's slightly out of focus, this wasn't the case with the Series 6000.
THE NEW Signature HD 20-60X Spotting Scope features HD lenses and an apochromatic lens system that eliminates color fringing
and delivers edge-to-edge resolution at all magnifications.
Its images are bright, contrasty and sharp from edge to edge, and the chromatic aberration (color fringing
) that's the curse of cheap cameras is absent -- either because the iPhone lens is particularly good, or because it's processed out by the software.
With the new family, a single 80x80mil device will typically replace four 40x40mil LED chips, which simplifies packaging and optical designs, while minimizing color fringing
and shadow effects common to multi-chip implementations.
Instead, we analyzed perceived qualities like color fringing
, edge sharpness, usable magnification, and resolution, which can be more difficult for the consumer to quantify.
Integration of LED lighting into the surgical suite--particularly with unique new LED arrays--provides a very high color rendering index (CRI) and the ability to control and vary the color temperature of the white lights without color fringing
and color shadowing.
* The ability to provide a crisper spot with no color fringing
or rainbow effects.
Tthe image suffers from color fringing
and becomes blurred.
I loved it more than the 10- or 15-inch Newtonians or the 10- and 12-inch Cassegrains that I had made." The image is crisp and clear, with hardly any color fringing
even on bright objects.
