Re: [ccp4bb] O/T: microscopes

[Jens T. Kaiser]

I can only recommend the Motic microscopes. i'm very impressed for $1,70O incl 
camera, not as sturdy as Leica (my favorite) but very good image quality. 
Drawback: no cold light source. But you can get a gooseneck light and do top 
illumination. Do not buy their polarizer, though.

Cheers,

Jens

 Dear Clint,
 Jerome is right. Do not expect to get a stereo microscope (these are
 more or less two microscopes within a smart arrangement) for this price.
 We purchased recently a Leica M205A, which defines the quality and price
 for a high-end system. It has a magnification range using a 0.8 plan
 objective and 10x oculars of 6-160x at a working distance of 90mm. The
 price for the objective alone is around 3000 US$, the full system with a
 CCD camera and the Leica application suite software cost then 13x more
 then you are expecting.
 Best regards,
 Uwe

  1) you are willing to buy a second hand of quality brands like Leica,

  2) you buy a low quality brand and you will later regret having done
  that .
 
  My two cents of advice, go for a SECOND HAND or, get more funding i.e.
  at least triple the amount

[ccp4bb] O/T: microscopes

Hi,

I am looking to buy a modestly-priced zoom scope for x-ray
crystallographic purposes ($2-3000).  Does anyone have suggestions about
what/where to possibly find this?  I currently have a cheap one that goes
from 7.5-50X, but I'd like something with a little more magnification, a
better light source and better optics.

Thanks,
Clint

Clint,

We have a Leica MZ125 scope with a Leica KL1500 LCD lightsource.  It has
adjustable zoom from 8x to 160x with the 16x occular lenses but can do up to
640x with a different occular.  We also opted for the optional optical
micrometer and polarizing lenses for looking at birefringence.
Additionally, they sell an attachment for hooking up a digital camera to
take pictures of your crystals.

This scope went for about 8k or so a year ago which is a little more than
you're looking to spend but the optics are great and it beats out any scope
I've used thus far even though I've only been doing crystallography for 4
years.

Cheers, Jim
