High Resolution Lenses
The High Speed lenses (HSF) have been developed for applications with large sized high-resolution sensors. The HSF-lenses feature a minimum distortion, a high relative aperture and a very small light loss in the corners. The following focal lengths are available: 25, 30, 35, 40, 45, 50, 75 and 95 mm. They are applicable in the visible spectral range and are optimized for focus distances from 250 mm to infinity. The lenses have high-quality mechanical parts with a high-grade steel flange and can be supplied with a F-mount or a PL-mount. The focus drive is designed as a multiple thread and can be fixed manually. All of the HSF-lenses have a manual iris diaphragm with click stops.
