The Schneider EMERALD 21-1070074 low distortion lens offers an image circle diameter of 43.2 mm. It is compact, robust, and optimized for imaging close 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.
The recommended working distance is 327 mm to infinity.
The flexible V48 mount enables pairing with an accessory for C, M42x0.75, M42x1.0, or TFL mount cameras.
