Description
Designed for students and professionals preparing for the ABO certification exam or wishing to quickly brush up on optical formulas, this
easy-to-use workbook contains optical formulas, definitions, and walk-through problems with practical examples throughout. Rather than
searching through dozens of optics books, readers will find all relevant information here in one source. Coverage includes everything
from sine, cosine and tangent to resultant prism and resolving prism to polarized filters - and much more!
