 Our wavefront sensor systems include:
- FrontSurfer stand-alone software for Windows or Linux. The program reconstructs the wavefront from a spot pattern obtained with hexagonal, orthogonal or random Hartmann (-Shack) mask with arbitrary number of subapertures. The software supports standard video interfaces on Windows and Linux. In "Alignment" mode the software is capable of real-time dynamic display of low-order aberrations in polar coordinates or bar-graph format. In the feedback mode, the program couples with OKO deformable mirror and can be used for low-cost real-time adaptive optics.
- FrontSurfer calibrated Hartmann masks with hexagonal and orthogonal geometries, designed to work with 1/2 inch CCD arrays. Can be supplied as a stand-alone component (square 10x10mm) or in a C-mount compatible head.
- Wide range of microlens arrays for Hartmann-Shack sensors. Each array can be supplied standalone, or mounted in a C-mount compatible head.
- FrontSurfer - compatible HR CCD and CMOS cameras with PC video interface for Windows and Linux operating systems.
Hartmann masksFlexible Optical offers calibrated Hartmann masks with square and circular apertures with orthogonal and hexagonal geometries. Masks are fabricated in glass and coated with patterned aluminum. Since the holes are positioned with very high precision and aberration of the mask is negligible, these masks can be used for absolute wavefront sensing, without calibration on a reference light beam.

Size of each mask is 10x10 mm Microlens arraysFlexible Optical produces high-quality replicated microlens arrays specially for the use with FrontSurfer wavefront sensors. As a standard option, we offer a hexagonal array of 127 microlenses with a focal distance of 15 mm and a pitch of 300 µm, mounted in a C-mount.
Besides, Flexible Optical offers a range of microlens arrays fabricated in glass and fused silica with small numerical aperture and 99% optical fill factor. Microstructures provide for optimum spectral efficiency (UV to far infrared) and for the best mechanical and thermal stability. These arrays work with very high optical loads. To provide a cost-efficient solution, all listed arrays can be replicated in series in plastic. Microlens arrays with orthogonal or hexagonal arrangements are available. Positive orthogonal arrays
