Dear all,
Here's another non CCP4 question: does anyone know a cheap alternative to
set up a UV source at 280 nm? I&#x

It is not the light source that is expen$ive, but rather the microscope
optics and the camera.
Standard optical glass has a fairly high absorption in the UV
One more thing: do not forget that 280nm UV is extremely harmful to
human eyes and skin.

Hello,
You may want to have a look at the UV LEDs, which should be the cheapest
option if you only need a specific wavelenth.
I found this on google: http://www
I put an array of UV LEDS on a ceramic block and connected to a power source,
as a means of detecting very small crystals once they are in the loop. The
most difficult part was supporting the LED block so that it shone onto the loop
but did not obstruct the user. The so-called UV LEDS are ofte

Alfredo,
It's not clear from your email what your purpose is: to illuminate a
crystal/sample on a microscope stage or on a goniostat. In either
case, you might check out Ocean Optics (http://
www.oceanoptics.com/). They have based their systems on fiber optic
light sources and CCD detec
Dear all,
Here's another non CCP4 question: does anyone know a cheap alternative
to set up a UV source at 280 nm? I'd really like to have one :), but I
really don't have the $20K Dlls needed to buy a UV/white light source
from the crystallographic vendors :(.
Thanks so much in advance for yo
