HASO R-Flex™
 
 

r-flexHASO R-Flex unites Imagine Optic's patented HASO Shack-Hartmann wavefront sensors with an auto-collimator and a focusing module to provide users with a versatile and turnkey solution for precision characterization of optical systems and surfaces. It's 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 HASO R-Flex 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/#=2 to f/#=30 to ensure maximum resolution, whereas custom models for special needs can equally be delivered. .

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

HASO R-Flex is delivered with HASOv3 wavefront measurement and analysis software that displays aberrations in real-time so that users can immediately see the effects of various positioning or alignment adjustments. It's small footprint allows to it be easily mounted onto translation stages so samples can be measured on-axis or at any point in the field.

1: Can be divided by 2 if the optical system under test is characterized by double-pass method. 2: Focal length of the module. 3: WFE is the wavefront error at the output of the module for the largest included round pupil. 4: Distance between the focalization point and the mechanics (if negative, the focalization spot is inside the mechanics). 5: YES means that the microlenses are imaged at infinity by the module.
