After World War II, Vladimir K. Zworykin developed the first practical commercial night-vision device at Radio Corporation of America, intended for civilian use. Zworykin's idea came from a former radio-guided missile. [15] At that time, infrared was commonly called black light, a term later restricted to ultraviolet. Zworykin's invention was ...
The Exotic Electro-Optics subsidiary of laser components maker II-VI has signed two multiyear agreements to sell its sapphire windows to Lockheed-Martin . The first agreement is for Lockheed's F ...
In 2022, II-VI acquired laser manufacturer Coherent, Inc.. [14] and took the name Coherent Corp. Carl Johnson served as II-VI's first CEO from 1985 to 2007. He stepped down as CEO in 2007 and was named chairman of the board, a position he held until 2014. [15] Johnson was succeeded as CEO by Francis Kramer, who had been president since 1985. [13]
At Eurosatory 2018, Ophir introduced another infrared thermal imaging lens to the range, the LightIR 15-75mm f/1.2, for uncooled 10–12-μm-pixel-size long–wave infrared (LWIR) detectors. [6] In 2019, Ophir expanded its family of cooled MWIR long range lenses, adding 900mm and 1350mm FLs, for use in aviation and observation systems. [7]
It went public in 1970. Over time, Coherent acquired other laser businesses and expanded to lasers for different industries and applications. From 2004 to 2021, it grew from $400 million to almost $2 billion in revenues, in part through a series of acquisitions. In 2022, II-VI Incorporated acquired Coherent, Inc. and took the name Coherent Corp ...

The Advanced Target Pointer Illuminator Aiming Laser, ATPIAL AN/PEQ-15 known colloquially as the "PEQ-15" [/ p ɛ k / / f ɪ f t iː n /] produced by L3Harris (originally designed and manufactured by Insight Technology, until their acquisition by L3Harris in 2010); is a multifunction IR Target Pointer & Illuminator, a.k.a. a Laser Aiming Module (LAM) for use as a rifle attachment, using a ...
ZnSe is used to form II-VI light-emitting diodes and diode lasers. It emits blue light. [2] [dubious – discuss] ZnSe doped with chromium (ZnSe:Cr) has been used as an infrared laser gain medium emitting at about 2.4 μm. [3] It is used as an infrared optical material with a remarkably wide transmission wavelength range (0.45 μm to 21.5 μm [4]).
