	What is Your Field of View? Four of our deveices are used to control field of view (FOV) and aperture: Optical Fiber (25° FOV, aperture = fiber diameter) Collimating Lens (0° - 45° FOV, aperture = 3 mm) Cosine Corrector (180° FOV, apterture = 3.9mm) Integrating Sphere (360° FOV, apterture = 25mm) Technical Tip The divergence (α) of a beam focused using a single lens is: tan(α) = d/f where f is the focal length of the lens and d is the aperture of the spectrometer.
