LIDAX is advancing high-precision optical systems for space and scientific applications through a portfolio of technologies designed for observation, measurement and analysis in demanding research and exploration environments. The company's expertise spans the design and manufacture of optical systems that integrate optical engineering, precision mechanics, and advanced control technologies to support Earth observation, deep-space exploration, scientific instrumentation and free-space optical communications. These systems are developed for operation across ultraviolet (UV), visible (VIS), infrared (IR) and X-ray wavelengths to meet the requirements of next-generation space missions.

A key component of LIDAX's portfolio is its telescopes and optical objectives, which are engineered to maximize light collection and image quality across multiple spectral bands. These high-precision optical assemblies form the foundation of robust observation systems used in scientific research and space missions. Complementing these capabilities are the company's space-grade laser collimators, designed using Structural-Thermal-Optical Performance (STOP) analysis to maintain exceptional optical performance under structural, thermal and optical constraints. The collimators support Free Space Optics (FSO) communication systems and scientific applications that require highly stable laser pointing accuracy.

LIDAX also develops custom Focal Plane Assemblies (FPAs) that capture faint celestial signals and high-resolution Earth imagery with exceptional sensitivity across UV, visible, infrared and X-ray bands. These FPAs are designed to maximize data collection while supporting advanced scientific observations and remote sensing applications. The company further applies its optical technologies to emerging scientific and space applications, contributing to missions ranging from deep-space exploration to Earth observation and advanced scientific instrumentation.

The company's optical technologies have been incorporated into numerous international space missions. LIDAX contributed to the James Webb Space Telescope by validating its mirror movement system under cryogenic vacuum conditions at 25 K. It also led the adaptation of the SMARTLID3 terrestrial LiDAR system for space operations, ensuring compliance with ECSS standards. Additional contributions include the BepiColombo mission through the MIXS focal plane, EarthCARE through active co-alignment sensor technology, PLATO through the design and manufacture of 26 CCD-based focal plane assemblies, Meteosat Third Generation through opto-thermo-mechanical systems for the IRS and FCI payloads, ExoMars Rover through a 532 nm Raman laser optical head and the MORERA project through the development of a compact refracting telescope operating in the 8–12 μm thermal infrared spectrum.

Supporting these developments is LIDAX's advanced engineering and validation infrastructure, which includes ISO 5 and ISO 7 clean rooms, cryogenic testing facilities, vacuum furnaces, vibration and thermal testing systems, helium leak testing laboratories, and specialised equipment for optical integration and verification. These facilities enable the company to design, integrate, validate, and qualify complex optical and opto-mechanical systems for demanding aerospace and scientific applications. By combining high-precision optical design, opto-mechanical engineering, advanced testing capabilities, and expertise across multiple spectral domains, LIDAX delivers optical systems that support space exploration, Earth observation, scientific research and optical communications. Its technologies continue to contribute to major international missions while enabling next-generation instruments for future space and scientific applications.
