NOVA Optical IR Instrumentation Group

The spectacular sensitivity and resolution of the observations, made by the largest optical-infrared telescopes in the world, can only be achieved by means of very sophisticated instruments behind these telescopes. Such instruments cannot be purchased "off the shelf" and the NOVA-ASTRON Optical infrared instrumentation group is one of the prominent groups in the field of designing and buiding these instruments.

From the beginning the goal has been to develop instrumentation on/for world-class optical telescopes for the Dutch astronomical community*. In the course of 25 years a wide range of instruments have been built, but in general the emphasis has been on spectrographs, on the infrared wavelength range and consequently on cryogenic instruments.

* In particular this concerns the facilities of the European Southern Observatory (ESO) in Chile and the Isaac Newton Group of telescopes (ING) on La Palma.

Introduction

Engineering state-of-the-art instrumentation is only possible when improved and novel techniques can be applied. Over the years the group has been involved in the design, development and realization of several (part of) instruments for groundbased as well as space observatories, gathering detailed knowledge on optical, mechanical, thermal, manufacturing and test engineering. Through the years this dedicated team built up a reputation in achieving excellent solutions in (opto-mechanical) engineering, and inventing new solutions to meet the stringent requirements. Some examples for this are:

  • Innovative cryogenic lens and mirror mounts
  • Super light weighting of aluminum structures
  • Polishing all aluminum mirrors to an excellent surface figure
  • On assembly manufacturing strategy

These research activities are imperative to stay at the forefront of the instrumentation development in the world, despite the pressure to develop quickly and at minimum risk real instruments. The team is capable of providing the full development process from feasibility studies up to the verification and commissioning of the instrument.

Route description 

Helena Kluyver Female Visitor Programme

The Helena Kluyver Female Visitor Programme is part of an on-going effort to improve the gender balance within ASTRON, JIVE nad NOVA. It is part of our commitment to equal opportunities and to encourage women to seek opportunities within a fundamental and applied research environment. Helena Kluyver was one of the first women to actively work as an astronomer in the Netherlands. Read more
