Editing BoPET (section)

===Science===
* Amateur and professional visual and telescopic [[solar filter]]s. BoPET films are often annealed to a glass element to improve thermal conductivity, and guarantee the necessary flat surface needed for even telescopic solar observation. Manufacturers will typically use films with thicknesses of {{convert|280|-|500|um}}, in order to give the films better resilience. {{convert|250|um|adj=on}} thickness films with a heavy aluminium coating are generally preferred for naked-eye Solar observation during eclipses.
* Films in annular ring mounts on gas-tight cells, will readily deform into spherical mirrors. [[Photomultiplier]] [[cosmic-ray]] observatories often make use of these mirrors for inexpensive large (1.0 m and above), lightweight mirror surfaces for sky-sector low and medium energy cosmic ray research.
* As a light diaphragm material separating gases in hypersonic shock and expansion tube facilities.
* As a [[beamsplitter]] in [[Fourier transform infrared spectroscopy]], typically with [[laser]] applications. Film thicknesses are often in the 500 micrometre range.
* Coating around [[Hematocrit|hematocrit tubes]].
* Insulating material for a cryocooler radiation shield.
* As a window material to confine gas in detectors and targets in [[nuclear physics]].
* In [[CT Scanner|CT scanners]] it acts as a physical barrier between the X-ray tube, detector ring and the patient allowing negligible attenuation of the X-ray beam when active.
* Spacecraft are insulated with a metallized BoPET film.
* The descent stage of the [[Apollo Lunar Module]] was covered with BoPET to control the temperature of equipment for lunar exploration carried in the Modular Equipment Stowage Assembly.
