NIRCam wrapped up in 2013 NIRCam being installed in 2014. NIRCam (Near-InfraRed Camera) is an instrument aboard the James Webb Space Telescope.It has two major tasks, as an imager from 0.6 to 5 μm wavelength, and as a wavefront sensor to keep the 18-section mirrors functioning as one.
Afocal photography works with any system that can produce a virtual image of parallel light, for example telescopes and microscopes. Afocal photographic setups work because the imaging device's eyepiece produces collimated light and with the camera's lens focused at infinity, creating an afocal system with no net convergence or divergence in the light path between the two devices.

The Near Infrared Camera and Multi-Object Spectrometer (NICMOS) is a scientific instrument for infrared astronomy, installed on the Hubble Space Telescope (HST), operating from 1997 to 1999, and from 2002 to 2008. Images produced by NICMOS contain data from the near-infrared part of the light spectrum.
The magnification of such a telescope is given by M = f 2 f 1 , {\displaystyle M={\frac {f_{2}}{f_{1}}},} Afocal systems are used in laser optics, for instance as beam expanders , Infrared and forward looking infrared systems, camera zoom lenses and telescopic lens attachments such as teleside converters , [ 3 ] and photography setups combining ...
An infrared telescope is a telescope that uses infrared light to detect celestial bodies. Infrared light is one of several types of radiation present in the electromagnetic spectrum . All celestial objects with a temperature above absolute zero emit some form of electromagnetic radiation . [ 1 ]

On a mountaintop in northern Chile, the Vera C. Rubin Observatory, which holds the largest digital camera in the world, is preparing to power up. ... The telescope will survey the night sky for ...
Flat-field correction (FFC) is a digital imaging technique to mitigate the image detector pixel-to-pixel sensitivity and distortions in the optical path. It is a standard calibration procedure in everything from personal digital cameras to large telescopes.
