Ok, you folks are just gonna love this one. Put down any hot drinks, plates of
spaghetti, etc. as this will make you wanna THPTTTT'S all over the place..
And Michael, good luck on getting the variance..

Can i put 22uF tantalum? I don't have 16 uF. Thanx!

I'm considering AFM for our diatom analyses on our inverted Olympus
IX70. I do not have direkt expererience with this technique. Is it
easy/quick to change back and forth from optical to AFM mode? How
quickly can you capture an image?

needs to be about 6kw with igniter.  new or used

Support for KDP2 might be slow again for a while. Last Friday my back
and siatic nerve problems came back like gamg busters really bad. I
see the doctor tomorrow.
I am trying to make a fix to the re-alignment optimization in the

I have a microscope which came with a blue and a green filter. I use the blue to
create a white background. I can find anyone that knows what you would use the
green filter for. Any help?

            its been a long time since I posted here, but this may be
of some interest!
I recently purchased, for the princely sum of around £40 UKP, a
replacement Laser reader assembly, for a Sony Playstation-3, With the

Does the diffracted mode of a diffraction grating that is being
illuminated by laser light have a bandwidth?  I understand that the
spectral line has a line width spatially, but what about in terms of
frequency.

Pardon my non-optics language - I am a product designer by profession
and need your help/guidance. Currently designing a special purpose
Flashlight based on 1W Lumiled LED (beam angle-125). My concern is to
get a very uniform spot of bright light of about 50 mm at a distance

Sorry to ask another question in such quick succession.
I need to have some details on the excited p states in Pottasium.
Bassically I want to know the natural decay time so I can work out
their frequency linewidth  so I can workout the required bandwidth of

I'm trying to develop a prop balancer for small planes, but I can't seem to make
a decent optical pickup.  Other companies make such balancers, so I know it is
possible. Following the practice of the other prop balancers, I want to place a
piece of reflective tape on the back of the ...

Hi sci.optics readers,
Has anyone already simulated a Carclo condenser for Luxeon LEDs with an
OptiCAD software like Zemax ? I can't find a mechanical drawing or a
ready-to-use optical model of this device which looks tricky. The

I know there's one guy in this group that will respond to this post,
even if he says he doesn't have one (hi Doug!)!
I really need a G325 Galvo motor ASAP.  Specifically I have a G325 DT
but I'm not sure if that DT really means anything.

Perhaps a silly question.
Has anyone heard of research to enhance solid state laser output by creating
an electron flow within the rod?
LiNb exhibits some superconductive properties at low temperatures.

I recently bought an M Series microscope  (Model BM-100FL). I want to
get a darkfield condenser to look at live cells, but I'm having
trouble determining which would be the correct one to buy. The
specifications provided in my manual indicate:
