Accessories for RFLEX 2

Translation stages

Our ΘXΘY rotation stage for angular alignment or the 5-axis stage that provides 2-way rotation around X and Y axes as well as 3-way translation along X, Y and Z axes is a perfect complement to the HASO R-Flex system.

Software add-on

HASO R-Flex is delivered with WaveView software, which is a leading wavefront metrology software providing 180 independent features. We also offer optional software modules including MTF (Modulation Transfer Function) and PSF (Point Spread Function) that increase the functionality of HASO R-Flex system.

Reference mirrors

Spherical reference mirror (Ø20mm useful pupil, R=15mm, F/0.75) for the calibration of HASO R-Flex in double-pass measurement configuration Flat reference mirror for autocollimation. Several options are available in diameter and flatness.

Single-Mode Laser Source (SMLS)

For those who want to use their HASO R-Flex at different wavelengths, we provide additional single-mode diode lasers to further expand the versatility of the system. Please contact us if you prefer to use your own light source.

MS-LAMBDA Metrology Light Source

The MS-LAMBDA is a metrology light source designed for wavefront sensing applications. It generates a spherical wavefront, ensuring an optimal illumination path at any desired wavelength.
