In my opinion, the Bahtinov mask is one of the most useful inventions for astrophotography. The traditional use of a Bahtinov mask is for focusing a telescope only and is not used for collimation of ...

Introduction: Gamma camera imaging with 99mTc-Pyrophosphate (PYP) is the standard for noninvasive diagnosis of transthyretin (ATTR) cardiac amyloidosis (CA). Current treatment with tafamidis arrests ...

Collimating is a method of aligning a light beam or stream of particles in a parallel path. The technique reduces particle distribution while ensuring parallel propagation. Collimation optics is the ...
