To the left of the lens table are two rows of buttons. Use these buttons to edit the table by row: either to delete the adjacent row or to insert a new row before the adjacent row. Up to eleven rows of lenses can be displayed at once. However, there is no hard limit to the number of lenses that can be entered. Whenever 10 or more lenses are displayed, a scroll bar appears at the right of the table that allows one to scroll the table display up and down to view the additional lenses

Instead, their initial offerings, Canon’s 18mp EOS M and Nikon’s 10mp V1 and J1 respectively, seemed more like an appeasement to their base and to those who might otherwise have been enticed by mirrorless pioneers Olympus, Panasonic and/or giants like Sony. But this criticism seems to have been rectified with the new full frame mirrorless releases.

“Bottled Water” 2018. Canon EOS M, 22mm f/2 STM. Manila, Philippines. They sure love their purified water in this country and in hindsight they were ahead of the game on this! But a lot has to to with not wanting to get sick from that tap water 🙂

“Funnel” 2018. Canon EOS M, 22mm f/2 STM. I’m not a huge fan of “state fair” type food, including funnel cake, but the light on that plate was delicious 🙂

I’ve used it sparingly over the years. Somehow, I never sold it. The turtle slow AF was reason enough to sell it but I think it’s the camera’s image quality when combined with that superb 22mm f/2 STM that made it a keeper for me. All pics here, unless otherwise noted, were made with the M and 22mm f/2 lens.

Version 1.2 fixed a minor bug in the Units menu.Note that both an executable (compiled) version and a LabVIEW source code version of this program are available. The executable version requires version 6.0 of the LabVIEW Run-Time-Engine. This is available as a free download from National Instruments. (Under Download Software, look for "All Software Versions", the LabVIEW, then your platform, then Run-Time-Engine, and finally 6.0.2.) However, the current version (7.0) of the Run-Time-Engine will not work with this program. You must download version 6.0.2.

“Turbulence” 2018. Canon EOS M, 22mm f/2 STM. In my opinion, the EOS M original is not well suited to action shots due to its turtle slow AF. But a shot like this is easy for the M 🙂

“Ride” 2018. Canon EOS M, 22mm f/2 STM. Note, the EOS M gives images that at first glance are reminiscent (in a good way) to photos from the latest generation iPhones, such as the iPhone X., in terms of color and sharpness. Of course, with an 18mp APS-C sensor, it also offers higher detail retention and resolution.

A description can be entered as a note of what optical layout is being modeled. This description is saved when the data is saved and will be displayed if a previously saved file is read into the program.

The files saved and read with the Open and Save commands are text files that can be viewed and edited with any simple text editor. Note that the calculated results are not saved in these files, but are recalculated after the file is loaded. Also, all lens data are saved, even if there are invalid lenses in the table (such as ones with a focal length of 0).

As mentioned before on this site, I’ve had my EOS M since 2013. I only got one when they were having a close out sale which included body and the 22mm f/2 STM lens for under $300.

Fans and critics (myself included) have complained that the big two did not give it their all when entering this market back around 2012.

Looking on these pics now, it does make me think quite hard about how I might acquire one of the new full frame mirrorless bodies from either Canon or Nikon 😊

To use the program, begin by entering the wavelength, initial waist size (radius), initial position of the waist, and M2. (M2 = 1 for a perfect Gaussian beam, >1 for real beams.) Note that in this program, the world begins at z = 0 and extends as far as the last valid lens or the last waist image. Then begin entering positions and focal lengths of lenses. Focal lengths can be positive or negative. When the program recognizes a valid lens (non-zero focal length, position greater than 0 and greater than the position of the previous lens), then it will calculate the beam parameters and display them. It will also display the lens and the propagated beam in the graph near the bottom of the screen. If there is a list of lenses, the calculations and display will only continue as long as the each lens meets the above criteria. Additional entries past that point will not be calculated or displayed.

Thanks so much Victor for your kind words! Great advice on the 5DII! I have a review of it somewhere on these pages and at today’s prices it might be the best DSLR bargain! Best Regards, Sam

With the recent release of the Canon EOS R system, and the Nikon Z6/Z7 just before that, it seems that these big two Camera Legends have finally embraced the mirrorless camera segment.

Once the beam is displayed on the graph, the graph axis and cursors can be manipulated to further study the beam. The X and Y scales are automatically adjusted, but can be manually changed to zoom in on certain features. The magnifying glass tool can also be used to zoom the graph, and the hand tool can be used to pan the graph. Two cursors are available which can be used to display the beam radius at any point. Each cursor can be dragged with the mouse. Also, the cursor most recently dragged can be moved one point at a time with the diamond-shaped directional palette. Cursor X and Y positions are displayed after the cursor names "Beam Size 1" and "Beam Size 2" in the cursor palette.

But don’t sweat it folks. I stand by my statements that I no longer crave the latest and greatest but that doesn’t mean I wouldn’t consider the new cameras once the prices come down 😀

This program is intended for calculating the propagation of Gaussian beams (laser beams) through thin lenses. It is based on a simple approach developed by Self in S.A. Self, "Focusing of Spherical Gaussian Beams", Appl. Opt. 22, no.5 (March 1983); 658. This approach is also described in the Melles Griot optics catalog (website no longer available).
