Resolution
object space resolution in lp/mm Or object space resolution in µm = 2 x pixel size (µm) PMAG of the system While one can quickly jump to the limiting resolution on the object by using the last formula, it is very helpful to determine the imaging space resolution and PMAG to simplify lens selection It is also important to
Limits of Resolution 3 Diffraction and Photosite Size
Resolution limits (lp/mm) for a perfect lens as a function of aperture and sensor photosite size are determined by simulation Results are shown for 20, 50, and 80 line-pair contrast ratios Smaller photosites always increase resolution and contrast (within the range of sizes and
Photographic System Resolution
No digital sensor achieves a system resolution close to that of the lens alone Film at 100 lp/mm with enlarger: Combination System Resolution (Rs) Camera lens lp/mm Enlarger lens lp/mm Format lp/mm LW/PH 50 60 24x36mm 35 86 1721 48 45 57x57mm 31 19 3556 30 30 4x5 20 75 3984 Film at 100 lp/mm scanned:
Lens Datasheet High Resolution Fixed Focal Length - National
Our TECHSPEC ® High Resolution 5 Megapixel Fixed Focal Length Lens-es are available in multiple focal lengths and feature multiple versions to optimize for different working distance ranges Perfect for use on high-end 5 megapixel sensors that require 145 lp/mm resolution, these lenses offer an attractive price-to-performance ratio
Whats a Megapixel Lens and Why Would You Need One?
LP/MM and can go up to over 200 LP/MM For example, a lens with resolution of 60 LP/MM on a 1/3-inch 1 3MP camera that has resolution of 133 LP/MM does not utilize the full resolution of the camera That's because the lens resolves only 60 LP/MM while the camera requires 133 LP/MM for its full megapixel resolution The lens cannot see enough
What Constitutes a High Performance 4K Lens FINAL
4K Lens Criteria – Optical Nyquist Spatial Frequency is 80 LP/mm for S35mm We have defined the optical Nyquist frequency for a 4K S35mm lens It means that this lens needs to be able to pass through its entire optical system 80 black and white lines within every millimeter of the

at 3 CTF of about 43 2 lp/mm But by dividing the CTF curve “MCP + Sigma lens” by the CTF curve of the Sigma lens, the CTF of the MCP only can be extracted The equation exp(-0 063 f) is a good approximation of this new curve and results in a resolution at 3 CTF of about 55 6 lp/mm which fits very well the specified 56 lp/mm mentionned by
