The Schneider EMERALD low distortion lens offers an image circle diameter of 43.2 mm. It is compact, robust, and optimized for imaging objects with a uniform image quality over the entire sensor area. The 400 - 1000 nm broadband coating makes it suitable for applications in the visible and the near infrared spectrum.
The iris is locked with a thumb screw. The focus is set by rotating the main barrel via an internal thread and locked with a locking collar that resists vibration.
This 'LD' version is optimized for longer working distances, ranging from 553 to 2830 mm. However, good images can be obtained as close as 54 mm. We also offer the 'SD' version that is optimized for shorter working distances.
