This came from an electronic device's motherboard. Hope someone can identifu it.

Mike the link is not working for me giving a server error message.

Thank you Rik for clearing this.It's obvious that a low magnification microscope objective (1x-2x) has no lack compared with a macro lens at same magnification. Not to mention the small image circle these objectives always have.

Hello Des. To me the best camera is the one that suits best to the rest of your setup. To be more specific: 1)If you are not using flash then you definitely need an efcs camera or you must somehow mount the camera without contact with the trino head., 2)No microscope objective (with the exception of...

Think the calculated NA is incorrect. NA~1/(2*F) for small NA, thus NA~0.1786 about twice 0.089. Also I assume you are referring to green wavelength which is ~0.55um, not 550um, which should actually be 550nm. So the resolution predicted by the Rayleigh Criterion is ~1.88um! Best, Mike From WiKi. "...

Sorry if this is a bit off topic but I was ready to ask why someone would use a T/C with printing nikkor. Then I decided to do the math by myself: Printing nikkor has a f number of 2.8 This equals to a NA of 0.0.089 I used the following formula: NA=M/Sqrt(4*f^2*(M+1)^2+M^2) where M=magnification=1 a...

Thank you Klaus.I'm looking forward for these heligon manuals.

Excellent images

Hello Lou. Did you try 436nm or 546nm version?Just for reference I think you must post a single color image (no stacking)
thank you in advance

Haris

Lou many thanks for sharing these information with us. Personally I would like to see how these lenses rendering colors (I know that they are optimized for single wavelength use) but there is always the possibility to be acceptable since you are actually using a tiny central segment of a huge image ...

Waldo this may reveal more information under polarized light.

Your chips semiconductor photos are among the best I have ever seen. Which 4X Inf. 0.1NA objective was used for this photo? Does it cover the FF sensor of D800?

It is called condensation.Put the objective on a warm and dry place (35c).You can use some silica gell inside a jar.Leave it at least 24 hours.You will be probably ok.

HarisA, your second shot shows very nice color, at least at this reduced magnification. What lens is that taken with? Maybe some of these lenses are color-corrected. Maybe the TV versions? If you blow up the sharp part of that image (the lips, it seems), are color aberrations visible? Lou these are...
