Increasing (i'dont' know in english for gamma) is constant for each position of L1.

gamma is constant for each distance between object-L1. I can move object several time and gamma is constant....

When i move L2, gamma is not constant but i move a little bit ;)and dw/de is not big.

If the diagram is to scale it looks more like 4 or 5 cm (=40 or 50 mm).

OK.

So then your diagram is either out of date or not to scale.

In either case it is not much help.

I do not understand your ray diagrams either. It looks to me like your ray diagrams show only two lenses, but your system has three lenses.

I think no one else will use your system if they don't understand it.

Again, I recommend to show a photograph of your system, with a ruler in the picture, with all lenses showing (not hidden inside tubes).

Perhaps then we will be able to understand.

Best regards,

Hum objective + lens tube = 1 lens for me = L1

For example with a x10 that means image is 10 x more tall with a lens of 20 mm (lens tube = 200 mm but it's not important).

In my case raynox is L2

It's possible to change my system with 2 lens fixed. In this case just object or just camera (without nothing exept for dust) move. Gamma could be constant if i see the simulator.

Then why did you increase the separation between those to 25 cm?

Because i don't want rebuilt my system :). More short is normally the same thing.

Frederic,

At http://www.photomacrography.net/forum/v ... 560#177560 , you wrote:
ploum wrote:tube lens is Inside

Change DCR 250 by DCR 150

lens tube is more far than objectif = 25 cm

Camera 0 cm - lens RAYNOX 8 cm - Lens tube 18 cm - 43 cm objective
Does that description match this last photograph?

Do I understand correctly, that you have the Raynox DCR-150 stuck directly on the front of the camera, with no added extension?

Small extension = 8 cm between sensor and raynox dcr 150 and 8 cm between raynox and lens tube.

A question... the lumix have their objective attached between the Raynox and the body camera? or there is only the Raynox in front of Lumix body?

In this system Lumix is alone.... with is raynox. I try an variation with a fixed raynox and a lumix alone without raynox fixed....

The blue cross with a fov 1.1 mm is done like that.

Hi,

sorry for my english. I have rebuilt my system. Now, it' more short.

camera move alone without lens.

Here i present photo of target 1 mm with 45° angle.

I a use width growth Gz in my system. Gz = Gy* Gy

for delta Z object = 0.7/1.41 = 0.5 mm camera advance for 20 mm.

Gz = 40 and Gy = 6.2. These 6.2x is obtain with an objetive x10 with raynox dcr 250 with focal distance of 125 mm ( x10 * (125/200).

With an angle of 30° of mire. I obtain these 3 images.

4x ON=0.1 sharp for 120 microm => width 60 micrometer
5x ON=0.14 sharp for 70 microcom = width 35 micrometer
10x ON= 0.28 sharp for 20 microm =>width 10 micrometer

Numerical aperture =AN

Width of field WF is a fonction of AN

i found WF = k/(AN*AN)

with my measure i found k = 0.6 (in micrometer)

And width of stacking

Width Staking = Gz x PdC = Gy[sup]2[/sup] x pdc = [Gobjective x (focale lens /focale standard]2)x (k/ON[sup]2[/sup])
 
Give 2x and ON= 0.055 => WS = 300 micrometers
          5x and ON = 0.14 => WS = 300 micrometers
          10x and ON = 0.28 => WS = 300 micrometers
        20x and ON = 0.42 => = 550 micrometers

Here a link in french

I explain than diffraction is predominante to circle of confusion. This circle don't exist in normal use (sensor definition superior at image résolution)

For mitutoyo's objective and APS-C 24 Mpix only diffaction exist
