California-based 4D Technology has received several orders for its short-wavelength infrared (SWIR) optical metrology instruments from leading aerospace, defense and communication technology companies worldwide. These will support the promotion of optical communications in the 1535-1565 nm wavelength band, known as the C-band. The technology offers data transfer rates thousands of times greater than traditional radio frequency communications, making it ideal for data-heavy applications. While optical communications possess advantages over RF systems, including cost reductions, lower susceptibility to detection, interception, and jamming, they also pose manufacturing and measurement challenges. 4D Technology&https://adarima.org/?aHR0cHM6Ly9tY3J5cHRvLmNsdWIvY2F0ZWdvcnJ5Lz93cHNhZmVsaW5rPWt5WjdTWGVWSGR3QXBic0NhZGZFZUZsZ2lIbmlrZEZkNmFXNXJjbEF2TUV4NVl6aExRbTlOTWxSMlVUMDk-8217;s SWIR metrology systems provides precise measurements of wavefront error, surface figure, and surface roughness at the critical SWIR wavelengths, reducing the demands for vibration isolation and the cost of testing critical optics.
