My 445 setup

Some photos of my TEC cooled single 445 setup being built.

Nice job. You certainly shouldn't have any problem with cooling. Are you adding any additional corrective prisms/lenses?

There is some intentional space that could be used for extra optics.
But I become less and less convinced of their necessity ...

What collimators are you using?

wow, a very nice setup!

Nice, How did you ensure you don't have a thermal short around the TEC?

@ireedz
I tried a few but I guess I'll settle with the o-like.

@dnar
I use 4x simple TO-3 isolation to prevent thermal conduction.

Nice idea! Thanks.

BTW the box is from Hammond
