I am looking for a stereo zoom microscope that I can mount my Nikon FM3a on.
Would the Konus Diamond 20-40x be a good one ?  What worries me about this
one and others like it is that the camera would be hanging out over the
microscope, thus make it unsteady.  Any help would be ...

I am considering outfitting my lab bench with transmitted DIC
capability.
I would like to do it as economically and efficiently as possible.
I have a number of Zeiss Standard/Universal/PhotoMic stands available

I have a Molectron Power Max I purchased from Molectron some ears ago.
At that time I purchased a PM10-19C sensor head that has a LM-25DB
conector that plugged into the Power Max meter.
Now I've purchased a PM150-50A. This one has a 4 pin Molex (1 pin for

I'm looking to modify a SMPS power supply that came with a 100mw DPSS
module from mains operation to battery operation. My thoughts on this
would be to simply measure the voltage across the LV (diode/tec)
section, and substituting in a battery of appropriate value, along with

hey everyone,
I have a sharplan CO2 Laser and I'm having some trouble reaching
maximum output..
although it's rated for a max output of 60W after it runs its self test

I found this PLAPON 60XO on EBAY at this website,

want to get ripped off.  Is anyone willing to offer ...

Hi, there,
I am looking for an adapter that could connect a digital camera to our
Olympus BX-60 microscope. The microscope currently has a video camera on
it via a c-mount tube (U-PMTVC).

Has anyone had recent experience of ordering from Roithner?
I have tried to email them a couple of times and have had no response.
Do they have a shutdown during the Summer?
Regards,

I am a beginner in the field of optical design, my current working is
in optical sensors.
recently I have managed a free version of OSLO called OSLO edu.
I have seen the posts from the very founder of the company and

The following's in reference to ambient far infrared radiation. Going
from high reflective index to low reflective index has low critical
angle. It seems logical that a great deal of radiation emitting from
material with high reflective index into air or vacuum should reflect

Hi all...
I'm trying to measure object forms with speckle interferometry and two
wavelengths
LAMBDA_synth = (lambda_1*lambda_2) / (2*|lambda_1-lambda_2|)

On RentaCoder one of the coders thought I just wanted him to change the
extension from WAV to BMP.  Another coder brought up the complexities
of actually converting WAVs to JPGs and back again, because JPGs are
compressed.  And someone else asked me how they could actually convert

How does one determine the maximum safe pulse width, duty, and current
one can apply to a IR LED?
Let's say it's a more or less ordinary 880 or 940 and the manufacturer
has listed its typical operating specs at a 20 mA drive, but has no

I am about to put together a supercontinuum light source (coherent
white light 450-1600nm) and was considering trying to route the
infrared portion of the beam into my Nikon TE-2000U and try some
epi-fluorescent/scattering experiments.
