SpotOptics Shack-Hartmann Wavefront Sensors

SpotOptics was founded in 1996 in Padova with focus on Shack-Hartmann wavefront sensors and their applications to the R&D and industrial world.
We offer complete solutions in the field of optics and software, covering any phase from the design of optics and software analysis to the fully developed end-user product.

We have about two decades experience in the field of optical design and software analysis and development. Our software specialization is in the development of software for image processing as well as industrial process control.

Our main product is a wavefront sensor based on the Shack-Hartmann principle. Our Shack-Hartmann wavefront sensors give the optical quality of a large sample of different optical surfaces: from the astronomical telescopes with diameters of several meters, to the DVD lenses and mobile phone with diameter of a few millimeters, to the human eye.

The use of our instruments is made very simple because of the advanced compact optical design and the degree of automation. The control software specifically developed by us allows the full control of the instrument, and our Shack-Hartmann analysis software gives you very precise indications about the quality of the optical element under test.

Finally a detailed diagnostics suggests how the optical quality can be improved. All the results from the software are available in a few seconds.

Our first Shack-Hartmann sensor was developed for the test of mirrors of astronomical telescopes. Our Shack-Hartmann wavefront sensor for astronomy PuntinoPro is now operative on several telescopes in Italy, Spain, India and USA. We have been consultants for a number of observatories and firms  for the alignment and quality control of telescopes. Thus PuntinoPro has been also mounted on several additional telescopes in Europe, Africa and USA.

While Puntino has been developed specially for astronomical telescopes, Optino/Opal/Lentino are Shack-Hartmann wavefront sensors designed and realized for the optical test in the laboratory and in the production environment and can test a large variety of optical elements both in transmission and reflection. Laserino is the sensor designed and realized for the test of lasers. We can test laser at practically any wavelength from UV to 10.6 (LWIR, CO2).

Finally we have developed a series of sensors for testing optical elements both on-axis
and off-axis. Sfera can test small lenses like mobile phone lenses, Stella can test large
lenses like telecentric lenses and 5Star can test objective lenses like zoom lenses mounted
on digital cameras.

We have developed further products in the field of optical alignment and in the medical
field.

We have extensive experience in the following fields:

  • Optics
  • Design & construction of instruments
  • Software
  • Instrument control
  • Fine mechanics
  • Image analysis
  • Statistical analysis of data
