Distance from the 6-way-cross to the floor (Not from the center, but from the bottom window to the floor.): [math]37\frac{1}{4}[/math] inches = 94.615 cm.

The distance from the Center of HRRL beam pipe to the floor is: 106.3 cm

From the center of the 6-way cross to quartz window: 11.685 cm

The distance from the center of the OTR target (also the center of the 6-way cross) to the closest position we place our first lenses is 13 cm.

Edge to edge OTR cone diameter size ([math]4\theta[/math] angle, ) at this distance is 2.665 cm.

Ring actuated Irises are designed for integration into a 60 mm cage assembly, where the movement of a lever actuated iris would be hampered by the cage rods.

Price: $75.50

Lens

Diameter: 5 cm.

We can use 3 lens system to hold image directly at the sensing area of the CCD camera. Sensing are of the JAI CCD camera is 6.49(h) x 4.83 (v) mm and field of view of our interest has a diameter of 1 inch.

Since OTR is placed 45 degree to vertical plane, one of the dimension of the OTR image actually is 1.796 cm. If we put this to vertical dimension of the camera and put the other dimension of image on the horizontal dimension of the camera, the magnifications we need to hold the view of our interest on the 50% of the sensing area of the camera will be:

HRRL Emittance Optics Lay Out:

In this telescope system magnification will be:

[math] M = \frac{f_2}{f_1} [/math]

So, we need to pick 2 lenses with optical length satisfy above ration. From the lower port of the 6-way cross the the floor is 94.6 cm. So, we have 90 cm place to place our camera system. So, I suggest we order camera with focal lens of 50 cm, 20, and 6, cm. These pieces can produce magnification that is small enough for experiment.

To avoid delay of experiment due to possible miscalculation, it is prudent to order 2 more lenses. One of them should be focusing and other one should be defocusing. In that case we can extend our optics as shown in following 2 figures;

Dear Sadiq,
The LCP01T can hold 2" lens.  The maximum thickness for the optics would be 17.8mm (the part in contact with the retaining ring).  
You can find the drawing for the part at http://www.thorlabs.com/Thorcat/21400/21473-E0W.pdf
Please let me know if you have any further questions.

Imaging System Test

Cage system were constructed, and 3 lenses with focal length of 500 mm, 100 mm, and 65 mm used to take image.

Out most ring on the target has a diameter of 27 mm.

Lights and Laser on

Following images are taken within distance of 45 cm (from target to CCD sensor).

Dr. Kim's suggestion:
Dear Sadiq,
Good Job!
If you have some free time, please would you try to improve brightness of the captured image?
As you can see, the captured rings are somewhat dark now.
If it is needed, you may install a small LED illuminator toward the screen and a light-shielding box around the cage.
The bigger lens are also helpful to improve brightness.
Sincerely yours,
Yujong Kim
