Oxfordshire, UK – Photography is a science and an art that is hard for anyone to master: there’s a lot that goes into getting that perfect picture. Photographers have to deal with the composition, colour, exposure, and sharpness when capturing an image. While half of the process is up to the photographer’s eye, the other half is predicated on the performance of the camera lens. Those in Oxfordshire looking to measure the quality of a lens in production can do so with Image Science.
Image Science is a company that manufactures and designs equipment for optical testing. This testing assesses the quality of infrared and visible lenses. With 27 years in their industry, they supply benches for production testing and R&D applications. They have a wide variety of equipment designed to test optical quality, like MTF measurement and other parameters that relate to performance.
They promise that their services can be adapted to work with their client’s specific needs. Besides offering MTF measurements, they also measure other aspects of image qualities. These include Field Curvature, Distortion, PTF, FOV, FFL, EFL, LSF, and absolute and relative transmission. Their benches can be equipped with detectors and sources for LWIR, SWIR, NIR, and MWIR spectral bands. Image Science also offers an in-house service to test MTF measurements. This is perfect for their customers who need to test pre-production prototypes. Those interested in checking out more can visit http://www.image-science.com.
Sharpness is obviously one of the most important qualities of an image – it determines the detail an imaging system can produce. It’s defined by boundaries between specific zones of colours or tones. It can be seen through graphs that show frequency, displaying how sharp or blurred an image is. Every lens, even the best, will blur images to a certain degree. There are many sensors available to test the sharpness quality of a lens; MTF is one of them. MTF is a product of the lens and sensor response, sharpening, and demosaicing algorithm. Sharpening usually boosts MTF measurements at the Nyquist frequency, which is the minimum rate at which a signal is sampled without the introduction of errors. This means that MTF measurements that are at or above this frequency are not an indicator of aliasing problems. However, they can be interpreted as a warning to problems.
Image quality is the most important aspect of capturing an image. This is why it’s important to catch a flaw in a lens before it is produced. Luckily, there are imaging companies, like Image Science, that offer MTF measurement testing to determine the quality of a lens.
