hmm.
On a side note, does anyone happen to have any "small" i.e. 5cm*5cm Peltiers? i am trying to make a cascade but i only have two sizes, 12cm and 8cm from defunct camping fridges.
thanks, -A

The Austrian firm Roithner Laser Technik sell 395nm 50mW laser diodes, and single and multi-chip power UV LEDs down to 350nm.
Just remember that a cup of mocha with a slice of fresh cream cake costs good money in Vienna!
