Raymetrics offers a wide variety of options within the standard product range. However we also produce fully customized LIDAR designs for products which cannot be built from our modular components. These can include entire LIDAR stations, Differential Absorption LIDARs (DIAL Systems) for ozone and potentially for other gases, and LIDAR components such as specialist telescopes.
Raymetrics telescopes are designed especially for LIDARs, with a focal point inside the telescope (as opposed to at the back where an eye-piece would be for atronomical telescopes). This reduces the size and weight, but more importantly also allows the secondary mirror to be smaller, resulting in reduced obscuration and up to 40% increased signal. Mirror coatings are designed for wavelengths beyond the visible light range (for UV and IR wavelengths). Optical quality glass is also used for telescope windows, thereby reducing chromatic aberration, which is extremely important for multi-wavelength LIDARs. Glass is also not used to focus, which also results in chromatic aberration. 200, 300 or 400 mm telescopes are available as standard, with other custom sizes on request.
