Interactive LINC-NIRVANA Image
Move your mouse over the orange dots in the image to learn about the components of LINC-NIRVANA.
LINC-NIRVANA uses a total of seven large enclosures to house its electronics. These enclsosures are sealed and climate controlled to ensure proper performance and low heat leakage.
Mid-High Wavefront Sensor
These two devices measure the atmospheric turbulence at an altitude of 7 km above the telescope and correct it using the Xinetics deformable mirror.
These two mechanisms de-rotate the sky, allowing the natural guide stars to fall on the correct locations in the Mid-High Wavefront Sensor.
These two bolt circles have been deliberately kept free to allow future expansion of LN capabilities.
These metal enclosures guide the many cables between the components of LINC-NIRVANA.
Ground Layer Wavefront Sensors
These two large instruments measure the turbulence directly above the telescope and feed the correction information to the LBT's adaptive secondary mirrors.
These small optical breadboards supply light for internal alignment and calibration of the instrument.
Science Channel Cryostat
The light from both telescopes ends up in the large (2 m high) science channel cryostat, containing both the science detector and the fringe and flexure tracking system
This lightweight pair of mirrors moves back and forth rapidly to remove differential arrival time of the wavefront at the two telescopes. To reach the necessary performance, the LN team developed a (patented) custom metal substrate.
Xinetics Deformable Mirrors
These two high-speed deformable mirrors contain 349 actuators each to implement the turbulence correction measured by the Mid-High Wavefront Sensors.
A pair of flat mirrors with a central hole direct the starlight from 2 to 6 arcminute diameter into the Ground Layer Wavefront Sensors.
Carbon Fiber Optical Bench
This patented large, lightweight composite structure provides stiffness and low thermal expansion for supporting the optical elements of LINC-NIRVANA
Light From Telescope
The semi-transparent yellow beams indicate the light path from the two telescopes of the LBT into the instrument. A special mirror above the science channel cryostat splits visible from infrared light.
