Re: condenser insert set

Nikon Achr 0.90 is not the best candidate to use with DF inserts, because of the internal design (I fixed your drawing a little bit). Internal "opening" (green) does not allow to go closer to the aperture . Of course, for the DIY purpose, opening could be widened, but it is kind a aggressive measur...

Re: condenser insert set

These are INSERTS into the condenser and close to the diaphragm. I’m pretty please with my set. What type of condenser are you using? On my 0.90 achromat the diaphragm resides c. 30mm above the bottom plate. http://iconoclastica.nl/download/condenser.jpg http://iconoclastica.nl/download/condensator...

condenser insert set

Has anyone tried one of these https://www.ebay.co.uk/sch/bauras/m.htm ... 7675.l2562 ?

I have always read these modifiers ought to sit near the diapragm, but in this contraption they are much lower. Isn't the position perhaps that important?

Re: Lomo MBD-1 microscope no. 693029

There's a rounded recess at the left, below where the plug is on the photo. I guess it is meant to sit there with the tube between the foot and the table, and the lamp is not part of the original package. The case is an interesting concept in itself: Each cover has four holes through which bolts go ...

Re: Does a DSLR adapter need a lens in it?

If your microscopy doesn't need correcting eyepieces then you do not need any lens in your photo pathway. No lens is always better than a cheap lens and possibly cheaper too. All what needs be done is to catch the primary image on your sensor. The primary image is located near the bottom of the eyep...

Re: Home adapter for microscope

It is quite large enough though centering is critical. The height of the image is nearly identical to what I see by eye, but of course the width is 1.5x wider. I made a mistake ordering the dovetail 0.5mm too small so mine is a bit off center. I use it with Canon APS-C; I am not familiar with the Ni...

Re: Home adapter for microscope

Hi Ivan, I made one, though for a different microscope/camea combination. But that should not matter too much, important is that when your camera is APS-C and the microscope has no colour correcting eyepieces, you can do without a relay lens, which makes everyting much simpler. My solution is descri...

Re: Condensers...

AFAIK, there are no theoretical objections to using condensers foreign to the brand of your microscope, unless they come along with custom above stage equipment (the phase rings/objectives were mentioned above). But there's also the issue of physical fit. However, if you know your way with e.g. 3d-p...

DIY filters

De Nikon Optiphot uses 45mm filters at the lamphouse. These filters are quite hard to find at all and bl**dy expensive when they are offered. For special applications they still may be worth it, but I think a simple ND filter or a blue color filter don't need expensive technology. I tried cutting fi...

on the why of NA and resolution

Is there a verbal explanation why higher apertures result in better resolution? I mean, the maths is clear enough, but why can a wider cone of light resolve smaller details?

Re: Using Motic K700 accessories on Leica MZ6 specifically Stereo Microscope Drawing Device

I have an old Wild MZ5 and it is 'the same' as the Leica MZ (other than the zoom system) so guess it is from when they rebranded.
I am actually using a black Wild photothube on an MZ7.5. As far as I am any judge, only style and colour don't match.
