Key Features
High resolution and high contrast
Supports 1.1” format 12 megapixel / 1” format, 9 megapixel cameras. Achieves 147 lp/mm high resolution from center to periphery.
Compact design Φ42mm
To suit 44 mm housings used for most 12 megapixel cameras, these lenses have a 42 mm compact design ideal for installation with high performance equipment.
Extremely low distortion
The optical distortion of this series is generally ~2%, (wide angle lens FL-BC1220-9M) or less, partially even <0.1 %. The resulting extremely low-distortion images are excellent for use in the image measurement field.
Bright and clear to the periphery
Despite the small diameter of 42 mm, the vignetting has been reduced to the minimum. Combined with the 12 megapixel resolution, bright, high contrast images are achieved all the way to the edges.
Floating focusing mechanism
The floating focus mechanism contributes to low distortion, high resolution images at all distances, from infinity right down to their minimum object distance, demonstrating maximum performance at any magnification. Compared with using macro rings, the floating mechanism maintains higher image quality throughout the entire focusing range, making it possible to capture images with the least deterioration even at the lens's MOD. This series is ideally suited to macro photography.
