Äpre Instruments Introduces New Affordable, High Performance Interferometer

S100 | HR model offers accurate, fast measurement and custom reporting

Äpre Instruments, a leader in interferometry for research, quality control and high volume production, introduced today their new S100 | HR high performance laser Fizeau interferometer for optical manufacturing.

The new system offers the affordability of a classic continuous zoom interferometer with the performance of a modern imaging system. It is ideal for optics professionals requiring accurate metrology of highly sloped surfaces and fine resolution of mid-spatial frequencies.

For companies looking to scale up, metrology is a serious investment, and the S100 | HR helps break down the barriers to producing more, higher quality optics. We’re excited to offer a system that meets the demands of today’s optical manufacturer without breaking their budget. As high performance spheres, aspheres and even freeform surfaces become the new normal, manufacturers need test equipment that is up to the challenge.

Using ÄPRE’s REVEALTM software, the S100 | HR can provide custom reports in as few as six seconds. The system runs on any 64-bit Windows® OS, 64-bit power that supports 4-megapixel acquisition and analysis.

Other benefits include:

  • Diffraction limited, 4-megapixel imaging
  • Better than λ/20 accuracy, even at 8 fringes/mm slopes
  • Vibration tolerant PSI and vibration insensitive carrier fringe acquisition

Äpre Instruments is now accepting orders for the S100 | HR Fizeau Interferometer. Visit for more information.
