The Kowa LM25SC lens was designed for the latest generation of larger format image sensors. Having an image circle of 16 mm, we recommend pairing it with cameras having a 10 to 16 mm (up to 1" format) sensor.
This lens delivers 160 lp/mm resolution at center, and 120 lp/mm in the corners, so it is appropriate for cameras having pixels as small as 3 microns. Kowa’s wide-band multi-coating reduces glare and refraction. Expect high performance even with the iris fully open.
The compact metal housing moves the aspherical elements independently, virtually eliminating optical aberrations across all working distances. The focus and aperture adjustments lock-down with thumb-screws to resist equipment vibration.
