High-Resolution, Low-Distortion LensProviding ultimate imaging performance for 2 and 5 megapixel cameras.
CA-LAR
Special optical design and construction
With a resolution of 250 units/mm and 180 units/mm for peripherals (CA-LAR12, 16, 25, 35, 50), the model has a resolution of more than twice that of conventional high-resolution lenses. This results in high-contrast images and enables stable dimension and appearance inspections.

Resolution at the edge of the image area
The CA-LAR Series can capture images at high resolution across the whole image area.

Minimum working distance
By using special low-scattering glass, we have achieved a working distance of 0.1 m for all models. This makes it possible to use the lens to the extent of its capabilities over a wide range without needing a close-up ring.

CA-LAR35, no close-up ring
The unit can be installed at WD = 100 mm without the need for close-up rings, allowing the lens to achieve optimised performance. Images with high resolution at the edge of the image area are obtained.
CA-LH35, close-up ring: 10 mm
Resolution worsens due to the effects of the close-up ring.
