Why we Love optics!

There's been plenty of action to report on lately, but not nearly enough time to blog it up!  So for now here's a cool movie clip showing the RSS disperser area - open to the world during the early hours of the morning while we were having trouble with the instrument.  One of the volume phase holographic gratings (left) was being illuminated at different angles with a flash-light & this makes the light change colour, as seen when it reaches the first lens of the collimator doublet (to the right of the open shutter).

We have much good news to report for HRS (& the coffee machine!), but those posts will take a bit longer so watch this space...
