IDAS Filter NBZ 2"Schmalbandfilter erzielen eine Kontrasterhhung dadurch, dass sie nur noch einen bestimmen Wellenlngenbereich des Lichts um die Spektrallinien des Wasserstoffs (H a, 656nm), Sauerstoffs (OIII, 501nm), Schwefels (SII, 672nm) usw. hindurch lassen.

Schmalbandfilter erzielen eine Kontrasterhöhung dadurch, dass sie nur noch einen bestimmen Wellenlängenbereich des Lichts um die Spektrallinien des Wasserstoffs (H-a, 656nm), Sauerstoffs (OIII, 501nm), Schwefels (SII, 672nm) usw. hindurch lassen. Die Filter können immer für die Fotografie eingesetzt werden, auch wenn der Mond am Himmel steht, oder als Filter gegen die Lichtverschmutzung in einer Großstadt. Dabei spielt die Länge der Belichtungszeit keine Rolle – auch Langzeitfotografien können getätigt werden. 

Der IDAS-NBZ ist ein neuer dualer UHC-Schmalbandfilter für H-Alpha und OIII Bereiche.

Zusätzlich wirkt er der Lichtverschmutzung entgegen und verstärkt den Kontrast vieler Nebelstrukturen erheblich. Der NBZ hat eine sehr hohe Transmission von 96% und steht den anderen Filtern von IDAS auch in punkto Qualität in nichts nach. Der Filter ist visuell und fotografisch (DSLR-Fotografie) einsetzbar und kann sogar noch an extrem lichtstarken RASA oder Hyperstar Systemen mit einem Öffnungsverhältnis bis f/2 erfolgreich verwendet werden! Der NIR-Bereich wird bis zu 1200nm geblockt.

Als dualer Filter lässt der NBZ sowohl Sauerstoff-, als auch Wasserstofflinien passieren. Der Sauerstoffbereich (OIII) liegt hier sogar zwischen 495.9nm und 500.7nm. Die Wasserstofflinien (H-Alpha) werden bei 656.3nm durchgelassen.

Easy Read with good case studies!!
Format: Paperback
I had to purchase this for my Advanced Pathophysiology class in my Acute Care Nurse Practitioner program. It is very easy to understand and have pretty good case studies. I like that the CD that accompanies the book goes into some detail in explaining the cases further and the disease processes without giving you the answers to the questions. It stimulates one to think!! Once this class is over I will go back from time to time to review!!

Helpful
Format: Paperback
This is a nice compliment to other classroom instruction materials. I am teaching an advanced pathophysiology course in a nurse practitioner program. This book is very helpful for students to put together the concepts of patho with the clinical setting. Will use these for in-class group assignments. Case-studies are thorough and offer a variety of different disease processes to choose from. It certainly does not offer a case study for every possible disease or clinical scenario, but does cover most major areas and enough variety in my opinion. Should be helpful in reinforcing the clinical significance of some difficult to understand concepts. I would recommend this text to course instructors.

Good book!
Format: Paperback
Very helpful book for pathophysiology. The CD not only gives you answers to the case studies but gives you clear details of the clinical Pathophysiology of a particular disease. Definitely recommend it to students going for their Master's degree!

No Answers Provided to Case Studies
Format: Paperback
The cases are helpful; however, realize that there are NO answers whatsoever to the questions presented in the cases--not a huge problem I suppose, b/c you can google everything, but certainly an annoyance. (esp. when there are multiple possible answers. The author states in the foreword that some of the cases are real; in which case, why not provide the justification presented in the patient's chart as to why that patient takes a particular drug, esp. considering that you may take a drug for its side effects rather than its therapeutic effect. . .anyhow. . ) I think if the author provided at least SOME insight/guidance to the cases that it would be much more helpful, but until then, I'm skeptical as to why others gave this book 5 stars.
