OPTICAL TESTING EQUIPMENT FOR SATELLITES

1.ISO collimator

The ISO collimator is based on a Newton system with a parabolic primary mirror of 700 mm diameter and f/4 aperture and a plane secondary which tilt the beam by 90 degrees. The wavefront error at 550 nm is smaller than lambda/25 RMS. The light sources are situated on the side of the tube and positioned by 3 crossed linear translation stages.
The tube of the collimator is supported by linear translation stages which allow to tilt the collimator axis within a cone of 2 arcdeg.
This device has been developed to qualify the optics of small size telescopes in the workshop.

2.Ground support equipment for HELIOS satellite

The equipment provided is part of the Optical Ground Support Equipment of the HELIOS satellite. Have been delivered :

All motions are computer-controlled. The accuracy of the angular positioning is 0.4 arcsec.

3.SILEX Collimator

AMOS was responsible for the study and the manufacturing of the silex collimator.

The tube of the collimator is made in INOX 316L material. The support plates of the primary mirror and the spider of the secondary mirror are in INVAR material (we minimize than the temperature effects).
The alignment of the secondary mirror with the optical axis of the primary mirror will be performed with the available motions on the spider and on the secondary mirror itself.
The inner wall of the tube as well as the mirror supports and baffles will be black paint (vacuum compatible) to reduce the surfaces scattering.

Weight: total value max. 150kg
primary mirror less than 9kg
secondary mirror weight negligeable (Ø less than 40mm)
mechanical housing less than 70kg

This collimator was designed and manufactured following the specifications of SPACEBEL INSTRUMENTATION and MATRA.
