Re: Comparison of projection lens and wide field oculars for imaging.

I feel I must apologize.
I just do not use a microscope the way most of you do.
To me it is an extension of my cameras. Just five inter-changeable lens.
Chromatic aberration in some of my work is a bonus and is used for effect.
Thanks.

Let's try again. Ocular and projection lens

This time I used a prepared slide of a Basswood Stem and used a 2x objective to give a wider field which is more representative of the image size I use. I also adjusted the length of the camera tube to achieve better magnification comparisons. I have also added a frame from a Canon 5D MkII with a Ni...

Re: Comparison of projection lens and wide field oculars for imaging.

Gekko: I never use the eyepieces to view a slide. I am not interested in things being parfocal. To me it is the image I see on the print that counts. The comparison was to show you can use a wide field eyepiece as a camera lens in lieu of specialized optics. Although the image may suffer a bit, eyep...

Re: parts to mount a camera on a ao spencer series 15

Re: parts to mount a camera on a ao spencer series 15

A USB camera plugs directly into the eyepiece tube replacing the eyepiece.
USB cameras typically have a 10x magnification factor.

Comparison of projection lens and wide field oculars for imaging.

This is actually two tests. One is a comparison of wide field oculars and projection lens for imaging on a microscope using a DSLR. The second is a stability (vibration) test using a light weight DSLR body as the camera. The oculars in the comparison are: A Labomed 10x Wide Field 22mm eyepiece. (30M...

Re: parts to mount a camera on a ao spencer series 15

Henryr:
Apochronaut was describing the ideal match between objectives and eyepieces.

Try looking through your oculars and objectives. See if you can actually notice any difference.
You can purchase an adapter for your Sony Cybershot for considerably less money than an objective or USB camera.

Re: parts to mount a camera on a ao spencer series 15

Henryr:
Your adapter must fit/clamp onto the tube, not the eyepiece itself. The eyepiece must be fully inserted into the tube.
These two photos show what I mean and did.

Those particular Zeiss eyepieces though, if they were with compatible objectives would be a better choice as ...

Re: parts to mount a camera on a ao spencer series 15

No and yes. No it will not work because you will need the eyepiece in the tube to use the Cybershot. Yes it will work if you mount the camera next to the eyepiece. There are commercially made adapters to do this. You may want to look at some of them and see if you can manufacture something similar. ...

When the camera image and the eyepiece image is the same, I believe they are said to be par-focal. I am probably the last person to ask about this area as I do not care.

Re: parts to mount a camera on a ao spencer series 15

If the inside diameter of the eyepiece tube is 23.2 mm, almost all USB cameras will fit directly into the eyepiece tube. No adapter is required.

Which USB camera to buy?
I suggest Touptek USB cameras.
They are slightly more expensive, but use the Aptina CMOS sensor.

Re: New here and please help me choose an appropriate compound microscope

To apochronaut . I believe your focus area for basic achromatic objectives is a bit off. Most achromatic objective have a flat field of 60-65% of the field of view. This is a quote from Microscopenet.ca "The difference between these three lenses is the focusing area which can be seen from the eyepie...

You should contact Gekko about the rocks. He gave them to me to make thin sections.

The Kentallenite sample was "softer" than most rocks I have ground and I was only able to get one slide. If you would like to contact me send an email to
