1355 Introduction To Optical Prisms

Prisms are solid glass optics that are ground and polished into geometrical and optically significant shapes. The angle, position, and number of surfaces help define the type and function. One of the most recognizable uses of prisms, as demonstrated by Sir Isaac Newton, consists of dispersing a beam of white light into its component colors.

  • Asphere Lenses: Let's Put The Pieces Together

    Ignoring materials, intended usage, manufacturability, or measurability often leads to an asphere lens that's too expensive to produce and too difficult to measure. The pieces need to fit together to ensure maximized performance and cost effectiveness.

  • Eradicating Preventable Blindness In The Developing World

    Worldwide, approximately 285 million people are visually impaired, and 80% of these cases are the result of preventable causes. To continuously observe patients’ eyes without irritation, Forus Health’s designs incorporate both stock and custom optical components from Edmund Optics to capture high quality images in both visible and near-infrared (NIR) spectra.

  • How Optical Coatings Impact High-Powered UV Lasers

    High powered lasers, such as those in the ultra-violet (UV) wavelength range (100 to 400 nm) are now used in medical, micro-machining, semi-conductor chip manufacturing, automotive, and defense, and aerospace technologies. UV lasers have distinct advantages over visible light and infrared lasers. 

  • Precision Optics For Military Applications

    This application note reviews a number of precision optics suitable for military applications, including corner cube retro-reflectors, integrator rods, mirrors, windows, and cube beamsplitters, as well as a wide variety of prisms.

  • Ultrafast Dispersion

    While the effect of dispersion is minimal for many types of laser systems, it is especially problematic in ultrafast laser applications. Ultrafast lasers are characterized by short pulse durations on the order of picoseconds, femtoseconds, or attoseconds.

  • Optical Flats

    An optical flat is a precisely polished flat surface, used as a reference against which the flatness of an unknown surface may be compared. Edmund Optics offers both single surface and dual surface optical flats in either ZERODUR® or Fused Silica.


  • BOROFLOAT® 33 is a UV-NIR transparent borosilicate float glass with excellent optical properties and smooth low scatter surfaces straight off the float process.
