The Ricoh C-Mount 75mm f/2.8-32 9MP Manual Iris Lens is compatible with 3.69 μm pixel pitch, 1" format industrial cameras with resolutions up to 9MP. From the center to the periphery, it has a high resolution of 135 lp/mm. Due to minimal degradation of resolution up to the periphery, the lens produces sharp, high contrast images. In addition, the lens comes with focus and iris lock screws.

φ42mm Compact Design

To fit in a 44mm housing used for most 9MP cameras, the lens features a φ42mm compact design. This make it suitable for installation in high-performance equipment.

Low Distortion

Troublesome lens distortions for image measurement or recognition have been reduced. The TV distortion is reduced to less than 0.1% with very little image distortion, making the lens suitable for image measurement.

Floating Mechanism Design

The lens is designed with a floating mechanism to control aberration across the entire focus range from the minimum object distance (0.1 to 0.25 m) to infinity. This reduces image degradation due to a loss of resolution or contrast as a result of changes to the working distance (distance to the subject). It enables a variety of applications from near distance to infinity.

Reduced Minimum Object Distance

Thanks to the optic design, the minimum object distance has reduced from a maximum of 0.45 m to 0.1-0.25 m for image capture at even closer distances.
