By Dan Fiore, Vice President What is a beamsplitter coating? Beamsplitter coatings can be deposited in a variety of different ways and perform in an array of different substrate scenarios. Beamsplitters can be applied to cubes, prisms, plates, hexagons, and pentagons. They can be polarizing, non -polarizing, or both, they can also come in narrowband or broadband varieties. If that isn’t enough to confuse you, these coatings can be comprised of dielectrics or metals, and can be designed to have an escape index of air, optical cement, or even optically contacted (a bonding process without epoxy).

Infrared vision is the ability for optical systems to detect heat signatures or waves of light emitted via infrared radiation. Thermal vision and thermal imaging are also commonly used terms in this situation since infrared waves emitted from a body are directly related to the body’s temperature: warmer objects emit more energy in the infrared spectrum than bodies with a lower temperature, hence their heat signature is more viewable. The human body, as well as many moving or static objects, are typically warmer than the surrounding environment. Since warmer objects produce more infrared energy than colder ones, it is easier…
