R-FLEX2

R-Flex2 unites Imagine Optic’s patented HASO Shack-Hartmann wavefront sensors with a collimator and a focusing module to provide users with a versatile and turnkey solution for accurate characterization of optical systems and surfaces. Its standard accuracy of λ/200 in double pass or single path configurations, and insensitivity to vibrations or atmospheric turbulence enable users to perform measurements that meet the most stringent requirements for reliable, repeatable results.

The adaption to the f/# of the optics to be tested is made thanks to a wide selection of optical modules easily swappable with different f/# to ensure maximum sampling points

The R-Flex2 is now capable to cover the 400 – 1100nm bandwidth allowing for instance to characterize chromatic aberrations. Characterizing large optical components or complex systems is performed easily as the exit beam is divergent,
thereby allowing users to set to focal spot to any point. When set at the center of concave mirrors, surface defects can be measured and analyzed.

R-Flex is delivered with WaveView wavefront measurement and analysis software that runs under Windows 7 or Windows 10. It displays aberrations in real-time so that users can immediately see the effects of various positioning or alignment
adjustments.

Its small footprint allows to be easily mounted on a translation stages so that the R-FLEX 2 can perform on-and off axis characterization in any point of the field of view.

R-FLEX2 SWIR

HASO R-Flex2 SWIR combines Imagine Optic’s patented HASO Shack-Hartmann wavefront sensors with a collimator and a focusing module to provide users with a versatile and turnkey solution for precision characterization of optical systems and surfaces in the Short-wave Infrared range. Its standard accuracy of λ/200 in double pass configurations, and insensitivity to vibrations or atmospheric turbulence enable users to perform measurements that meet the most stringent requirements for accurate, reliable and repeatable results. Furthermore, the system was designed to keep the possibility to use the  HASO SWIR independently and swap between configurations very easily.

Because different users have different needs, the f/# of HASO R-Flex2 SWIR can be adapted to each user’s requirements by choosing the focusing module best suited for the task at hand. Several options of modules are available in standard and Imagine Optic can produce customized modules on option.

Characterizing large optical components or complex systems is performed easily as the exit beam is divergent, thereby allowing users to set to the focal spot to any point. When set at the center of concave mirrors, surface defects can be measured and analyzed.

A flat surface, window or plane mirror can be characterized thanks to the collimated output beam of the R-Flex2 SWIR LA. The optics to be characterized can be up to 150 mm in diameter.

HASO R-Flex2 SWIR has been designed to cover the 1.0 – 1.7 µm wavelength range. This broadens the capacity of the HASO R-Flex2 SWIR to inspect optical components in term of chromatic aberrations for example.

HASO R-Flex2 SWIR and R-Flex2 SWIR LA are delivered with WaveView wavefront measurement and analysis software that runs under Windows 10. It displays aberrations in real-time, up to 20Hz, so that users can immediately see the effects of various positioning or alignment adjustments.

Its compact footprint allows to it be easily mounted onto translation stages so samples can be measured on-axis or at any point in the field.

HASO R-Flex unites Imagine Optic’s patented HASO Shack-Hartmann wavefront sensors with a collimator and a focusing module to provide users with a versatile and turnkey solution for precision characterization of optical systems and surfaces. This self-illuminated wavefront sensor has a standard accuracy of λ/100, λ/200 in double pass configurations, and insensitivity to vibrations or atmospheric turbulence enable users to perform measurements that meet the most stringent requirements for reliable, repeatable results. Even more, accuracy can be further increased if the measured aberration is close to the diffraction limit.

Because different users have different needs, the f/# of the HASO R-Flex self-illuminated wavefront sensor can be adapted to each user’s requirements by choosing the focusing module best suited for the task at hand. As the sample f/# defines the best focusing module, Imagine Optic offers factory models that are available from f/#=1 to f/#=15 to ensure maximum sampling points, whereas custom models for special needs can equally be delivered. Please see the product page of standard focusing units.

Recently, we developed HASO4 R-Flex50 for two wavelength ranges; 400-700nm (VIS) and 650-1100nm (NIR). This broadens the capacity of the HASO R-Flex to inspect optical components in term of chromatic aberrations for example.
