Products
ImageMaster® HR 2
Image quality testing with highest repeatability
The ImageMaster® HR 2 is our completely redesigned new version of the long-time successful ImageMaster® HR – the worldwide standard for image quality testing of small and medium-sized lenses e. g. for smartphone-, photo- and film cameras.
- High repeatability for all measurement parameters
- New Software and ease of use
- Extended range of measurable samples
More information
- Measurement values are highly stable and reliable, ensuring correlation worldwide
- Flexible software support in combination with mechanical features contributes to better correlation testing
- Optional implementation of encoders improves position accuracy, i.e. improvement of the accuracy and reproducibility of the focus position
- Absolute FFL/BFL measurement
- Many “off-the-shelf” solutions are available, for example Encircled Energy, Veiling Glare, PSF, and ESF
- SWIR upgrade for MTF measurement in the shortwave infrared spectrum: Proximity sensors in vehicles are an important feature for driver assistance systems. They operate in the short infrared spectrum (SWIR), so a suitable measurement system is required to test the image quality. Moreover, measurement in SWIR spectrum becomes more important, for smartphone lenses. With a measurement accuracy of ±0.03 MTF and reproducibility of ±0.01 MTF the system meets the highest requirements even for small apertures.

Software
ImageMaster® MTF Lab and MTF Studio Software
User-friendly software for research and development as well as laboratory work
The versatile functionality and high performance make the user-friendly ImageMaster® MTF Studio software package the preferred choice for R&D and laboratory work. High-performance functions help the user to optimize the measurement processes. The software offers high flexibility for measurements in the NUV-, VIS- and NIR spectrum. Automatic measurement sequences ensure easy operation and the data can be output in CSV/MHT. Several useful functions are integrated which help the user to scan and perceive the correct image position of the sample under test. Changing the measurement mode is easy and time-saving. All important measurements for the imaging properties are quickly accessible. One main feature key feature when using the software with the ImageMaster® Universal is the support of UV or IR detectors employing the scanning aperture method.
