An immersion suit, also known as a survival suit, is a type of waterproof dry suit intended to protect the wearer from hypothermia if immersed in cold water or otherwise exposed after abandoning a vessel, especially in the open ocean. Immersion suits usually have integral footwear, and a hood, and either built-in gloves or watertight wrist seals.
A common use of the term refers to protection from cold and wet environments at sea. Depending on type, they may be worn during normal work, in emergencies, or when exposed to unusual conditions. [1] [2] [3] Examples of exposure suits as a class include diving suits, [4] space suits, offshore survival suits, immersion suits, [1] and foul ...
Immersion lithography or immersion microscopy, optical techniques in which liquid is between the objective and image plane in order to raise numerical aperture; Immersion (mathematics), a smooth map whose differential is everywhere injective, related to the mathematical concept of an embedding
Immersion lithography is a technique used in semiconductor manufacturing to enhance the resolution and accuracy of the lithographic process. It involves using a liquid medium, typically water, between the lens and the wafer during exposure.
baptismós (βαπτισμός) refers in Mark 7:4 to a water-rite for the purpose of purification, washing, cleansing, of dishes; [94] [95] in the same verse and in Hebrews 9:10 to Levitical cleansings of vessels or of the body; [96] and in Hebrews 6:2 perhaps also to baptism, though there it may possibly refer to washing an inanimate object.

Oil immersion objective lenses look superficially identical to non-oil immersion lenses. In light microscopy , oil immersion is a technique used to increase the resolving power of a microscope . This is achieved by immersing both the objective lens and the specimen in a transparent oil of high refractive index , thereby increasing the numerical ...
A woman using the Manus VR glove development kit in 2016. In virtual reality (VR), immersion is the perception of being physically present in a non-physical world. The perception is created by surrounding the user of the VR system in images, sound or other stimuli that provide an engrossing total environment.
In light microscopy, a water immersion objective is a specially designed objective lens used to increase the resolution of the microscope. This is achieved by immersing both the lens and the specimen in water which has a higher refractive index than air, thereby increasing the numerical aperture of the objective lens.
