High Resolution Telecentric Lens for 1.1" Sensor by SWAROTEC

High Resolution Telecentric Lens for 1.1" Sensor

From the Idea to the Finished Solution

Prototype challenges

Due to the limited space available, the actual dimensions of the lens were tightly restricted. Using a smart combination of mechanical mounts and optical alignment the requirements could
be fulfilled and the working distance achieved with a precision of less than 1 mm.

Resolution and contrast

Modulation Transfer Function (MTF) at a wavelength of 460 nm.
The resolution of the lens is very close to the diffraction limit even in the corners of the sensor.

Longitudinal chromatic aberration

Longitudinal chromatic aberration in the visible spectral range. The lens is designed with an apochromatic correction. The offset of the focal planes for RGB-LEDs (typ. wave length 460/525/625 nm) is within 10 μm.
