About this title

Synopsis

Master the fundamentals of light, reflection, and refraction that power fire-control instruments.

This nonfiction reference explains how light travels through different media, how surfaces reflect and refract, and how these rules guide the design of optical devices used in weapons and targeting systems. It covers core concepts like the laws of reflection and refraction, indices of refraction, and the behavior of light at polished versus rough surfaces, all illustrated with practical examples.

The text then applies these ideas to real instruments, describing telescope components, reticules, eyepieces, and how to achieve accurate sighting and measurement. It also discusses range finders, internal adjustments, and compensation for thermal and mechanical changes to keep systems reliable in service.

Foundational optics: reflection, refraction, indices, and how they determine light paths.
Surface quality and material effects on light behavior in practical instruments.
Fire-control optics: objectives, eyepieces, reticules, and their roles in aiming accuracy.
Range finders and their internal adjustments, including self-compensating designs for field conditions.

Ideal for engineers, technicians, and students studying military optics and historical fire-control equipment.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
