Product Information: 6" by 9", Hardbound, Smyth sewn to lay flat, 462 pages, 452 Illustrations, 45 Tables.

Introduction to Lens Design with Practical ZEMAX Examples is based on an introductory lens design course taught in the Optical Science & Engineering doctoral program at the University of Alabama in Huntsville and sponsored by the Center for Applied Optics.

The book’s 38 chapters follow Dr. Geary’s classroom lecture syllabus, suitably augmented and expanded for the person interested in self-study. Included are more than 450 illustrations, numerous examples, problems and their solutions. While designed for self-study it is also suitable as a comprehensive introductory text. Although it is about lens design, the scope is general and will provide optical engineers and others with important tools and skills useful in a world which increasingly relies on optics in a wide variety of applications.

The book’s theme generally follows the historic development of the photographic lens. Ten photographic lens design problems are presented from the simple Wollaston landscape lens to the more complex achromatic telephoto. This book recognizes the fact that a modern lens design must thoroughly integrate one of the commercially available lens design codes into its presentation. While ZEMAX examples are used here, other software is not precluded. Manual (pencil and paper) thin lens pre-design calculations provide the starting prescriptions for every ZEMAX illustrated problem. Paraxial ray tracing, element power computations, and aberration calculations are utilized throughout. Consequently, all designs are firmly anchored by theory.

The design principles covered in the book include: lens bending, stop shift, symmetry, element splitting, color correction, aberration balancing, field flattening, and aspherics, as well as the proper use and construction of the merit function. Of equal importance are the analytical tools used to determine the quality of the design. Today, all modern codes are built upon a strong tradition of optical analysis. They can provide the user with a rich variety of numbers and plots (such as axial color and ray fan plots, spot diagrams, and MTF). This book will provide the reader with a thorough understanding of the origin of these numbers and what the plots mean.

My Dobermans favorite toy to destroy, and one of our recommended picks.
Color: Checkers - Elephant (Gray), Size: Large
Ok, here's an honest breakdown review. I have a 6 month old Doberman who shreds every stuffed animal and dog bed he's come across. He's one of the worst chewers I've owned. We have tried a WIDE variety of stuffed toys. That said, this elephant is his favorite toy. I have ordered 4 of them so far, and just ordered another 4-pack on a buy three get one free deal. The elephant stands out above all the other stuffed creatures from goDog for me as to durability. Hence why I keep buying more. But they usually last about 2-3 weeks on average. In our house, the poor creatures are subjected to vicious, crazy, shaking of the head, helicopter type rotation. It' so hard if it hits your bare arm or leg it actually stings especially when its wet. Then the old, put it between his legs laying down, tearing at the legs action. The limbs are usually the first things to go over time. But they are each almost self sealing, so you clean up as little fluff and keep using it. Eventually the pup reaches the main body and finishes it off. For a normal light to normal chewer, one of two will get you a long way. For those of us resigned to having zoomie type manic chewers that need a constant supply of toys, 2-3 week durability is pretty sound too. I do not recommend the green cheaper monster. It lasted about 45 minutes. The free replacement took about 3 days. Hopefully this aids you in your decision!

Very durable for rowdy pups
Color: Checkers - Elephant (Gray), Size: Large
This toy has outlasted any other dog toy I have ever bought. I have one large and one medium dog who share toys, fight over toys, chew them to death and still play with them. It might be because it isn't one of their favorites. I don't know. All I know is that our house is littered with dog toys in different states of destruction and this elephant toy has very little damage. It has definitely been in the dog toy rotation. I had this toy for 2 months without any major damage. The day I wrote the review the dogs tore the leg off! I still think it is a good toy. Some toys lose the stuffing or squeaker the first day.

Great toy for a smaller dog
Color: Checkers - Dinos Bruto (Purple), Size: Mini
This is a small, firm, sturdy toy designed for chewing. It isn't a soft toy and it does not have a squeaker. My dog is only 8 lbs, and this is a perfect size for her. I discovered these smaller toys through my groomer. Other manufacturers make this size, as well. The "hard chew" part indicates that this toy will not be chewed to death easily. The oldest one that we have is still in good condition. It's a baby duck (also available on Amazon) and it's over a year old. The dinosaur is colorful, easy to throw, and a really cute. Every night, my dog gives these small toys a bath, cleaning them up by licking each one before going to sleep. It's as if they are her babies. Since she never had a liter, my vet said that they are about the size that her babies would have been, so she may see them as her babies. She treats them well. Every now and then they go" swimming" in the washing machine and come out looking bright and new again.

Updated, still going !! didn't last two minutes.
Color: Checkers - Elephant (Gray), Size: Large, Color: Checkers - Elephant (Gray), Size: Large
I hated giving this a 1 star, because it was so cute when I unpacked it today. I just gave it to my dog and in less than two minutes he has a hole ripped in it.! he loves it so I don't wanna take it away from him, but I'm sure it's going to be gone in another few minutes. Why can't someone make a stuffed animal for a dog that lasts like they say so on their listing? I really should take it away from him and send it back, but I don't have the heart. I had to come back and give this a better review. it deserves at least four stars because even though he ripped holes in it, this one has lasted way longer than any other toy. He's actually still playing with it, and it still has some crinkle left to it so he didn't destroy the whole thing as quickly as he did other stuffed animals. I will certainly buy another one because at least it lasted a week so far!

Looks Nice But Destroyed by my Lab
Color: Checkers - Elephant (Gray), Size: Large, Color: Checkers - Elephant (Gray), Size: Large
A really cute little elephant. My lab loved it and carried it around for a week. Then the elephant began losing body parts. Both legs are gone now plus the big squeaker. Lab still likes the elephant and carries it around. Its loosing stuffing and the real question is what body part is next. Its nice but not tough.
