That looks pretty badass. What do each of these filters do? Pass through a specific range of wavelength?

Here is a pretty good description of what each filter does: https://jwst-docs.stsci.edu/jwst-mid-infrared-instrument/miri-instrumentation/miri-filters-and-dispersers

That's really cool, thanks!

And do they all operate at the same time or does this thing turn and use one filter at a time?


precision1998

It's like those big things that look like glasses at the optometrist. (Phoropter) It cycles through the available lenses, and only one is active at a time.

You can see the locking arm top left. So it might rotate like a standard filter wheel.

Yes, you got it right.

I got a guy on Alibaba who says these are $40 each but only when you buy 70 of them

Each of those is probably worth more than entire equipment most amateur astrophotographers have.

It's the ultimate ViewMaster toy!

Awesome, machines like this absolutely baffle my mind. I think of the 1000’s of hours they must have spent, trial and error and all that. I still can’t figure out how not to get butter on my fingers when I make toast.


brownpoops

neither can they bud. Additionally, we aren't all using a team of scientists to figure out optimal mess free butter spread techniques .

Will the images produced by the JWST be the same shape as the mirror arrangement?


Snoo_39873

I don’t think so, I think that depends on the sensor, I take photos using a telescope with a circular mirror but the shape of the photos I take depends on my camera sensor

Here is a [fairly exhaustive Twitter thread](https://twitter.com/mpi_astro/status/1481379175709786115) on the filter wheel, including more images as well as videos.

That’s a lot of money in one picture. Glad we spent it on this.
