SunLab Image Capture & Processing

Here is a brief description of the data path from the RED 8k back. Data leaves the DSMCII RED camera through a RED Jetpack SDI that routes the compressed data through a Gigabit Ethernet cable that goes through a 24 port router. Directly from the router into 100tb remote servers at general compression. These will…

A highly successful project that broadcast the eclipse in many digital formats in 2017 from Carbondale, Illinois. The SunLab will be re-built at Lunt Solar in Tucson and will be a mobile and robotic facility that will capture the daily activity…

How a Lunt Etalon is Made (Part 1)

Lunt Etalons are precision crafted at our manufacturing facility in Tucson, Arizona. We start with precision cut UV grade Fused Silica blanks that we purchase from a glass supplier in Massachusetts.We use UV grade due to the higher specifications that UV grade material has for reduced bubbles and striae. Both of which would negatively effect…
