Field of view vs focal lengthcanon

ACL’s range of static detection and industrial static control devices give technicians the tools for measuring static environments, fixtures, and personal controls. Managers can count on repeatable and reliable readings with every instrument.

The calculator below converts between the focal length f and the field of view (FOV) of a rectilinear lens. The formula that it implements is FOV = 2 arctan (x / (2 f)), where x is the diagonal of the film. The FOV is measured across the frame’s diagonal, and is therefore smaller across the horizonal dimension, and even smaller across the vertical dimension.

Until now all Pentax DSLRs use a sensor smaller than the standard 24 x 36 mm film frame. The lens still produces a 24 x 36 mm image, but the sensor only captures the central portion of that image — your wide-angle is not so wide and your tele is even longer. The calculator below takes the 1.5 x crop factor into account.

The Pentax fish-eye zoom lens has a diagonal FOV varying between 180° at the wide end and 90° at the long end. The Birds-Eye lens forms a circular fish-eye image with FOV of 180° across the image circle. All other Fish-Eye lenses form full-frame images with a diagonal FOV equal to 180°.

Staticide topicals eliminate electrostatic attraction (ESA) on all types of materials. Staticide ESD Safety Shield controls static by creating a dissipative surface and preventing electrostatic discharge (ESD).

ACL ESD Workbench products are designed for the electrostatic protected areas (EPA). From dissipative mats to protective cleaners, these ESD essentials control and guard against static harm.

The ACL Staticide® Microfiber Cloth provides superior cleaning performance for general applications where strengthand softness are required. The split-fiber construction allows more dirt, dust, and oil to be removed than traditional wipers.Where some microfiber cloths have an unpleasant tactile drag, ACL Staticide® Microfiber Cloth feels unusually silky to touch. Surfaces remain unscratched when wiping with or without the use of chemicals.For the best performance, soak cloth in water prior to initial use and allow it dry. For dusting, use dry. For cleaning, dampen with water. Avoid oversaturation. If using a cleaner, avoid detergents with bleach and abrasive materials like silica.

ACL Staticide's ESD-safe Metal-In Static Shielding Bags safeguard sensitive components from electrostatic discharge. Metal-In styles include open top and resealable.
