Integration of UIST in the UK ATC Labs

The complete instrument

• Jim, David and Martyn work on the open cryostat.
• The complete optical train and all modules, with the exception of the camera wheel.
• The single camera barrel has now been replaced by the camera wheel module.
• Mel, David and Jim complete the preparation for an earlier cooldown.
• Carrying out preliminary flexure testing using the UIST rotator. The cold cryostat with the mirror cover in place and without. Without the window cover, the first of four targets illuminated by LEDs and used for optical checks can be seen.
• The cryostat on its side for alignment checks.
• The wiring poles with array wiring and motor control panel are seen on the top plate.
• The super-insulation blanket.
• The front plate of the rad-shield with the baffle mounted in it plus detail of the baffle.

Array and EDICT Controller

• The bare MUX, carefully handled by Maureen.
• The bare MUX image of our optical target shows that software and electronics are working together
• The first infrared image with the 512x512 engineering array.
• The first light image on the science array, through teh full optical system (8 August 2001).

The integral field unit

• The IFU layout
• A long slit spectral image from the UIST engineering array (512x512 pixels only)
• The full 1024 x 1024 IFU spectral image of an argon lamp with wavelength coverage from 1.4-2.4 microns

The IFU components, polished

• The image slicer and the slicer mirrors, as manufacturered in the UK ATC workshop.
• The polished re-imaging mirrors
• The pupil imaging mirrors, as made at the UK ATC
• The final fold mirror.

Individual components and assemblies

• The image rotator has the field lens mounted.
• All of the modules are in place on the optical bench.
• The filter module in the workshop before assembly
• The periscope with the folding flats assembled in the lab.
• A top view of the periscope
• The mounted lenses of the 0.12 arc sec plate scale camera
• The ZnSe field lens and CaF2 window
• The optics bench provides mechanical support for the individual modules containing lenses and mechanisms.
• The radiation shield reduces the heat load onto the UIST components.
