With the OptiSpheric AF 500 INV, Trioptics presents a measurement system that is specifically designed for the precise measurement of flange focal distance and effective focal length of camera lenses. In addition to effective focal length, flange focal length is particularly important when manufacturing camera lenses. This determines the distance to the camera sensor, thereby influencing the quality of the lens.
With the OptiSpheric AF 500 INV, Trioptics has developed a measurement instrument with which these parameters can be quickly and reproducibly measured – regardless of their physical length. Mounting lenses on the measurement instrument is additionally facilitated by the simple implementation of customer-specific sample receptacles. In addition to determining effective focal length and flange focal length, the instrument can also measure back focal length, radius and MTF for camera lenses with a length of up to 300 mm.
