HYSM-AS2000 series scheimpflug lenses adopt spherical + aspherical lens design
Large aperture F4, receiving more light
MTF is close to the diffraction limit
Ultra-low distortion, less than 0.02%
Small size helps reduce the overall size and weight of the sensor
The chief ray angle (CRA) at the edge of the field of view(the smallest in the industry), and the high CMOS photoelectric conversion efficiency improves the energy uniformity between the center and edge of the field of view.

If you build a monocular structured light system in a scene with a small object distance, you will generally encounter a depth of field problem. Because monocular structured light acquisition uses triangulation, there will be an angle between the camera and the structured light. If the light machine projects vertically.
When the camera is tilted to shoot, it will involve focusing at different positions on the target plane. Insufficient depth of field will cause some places to be clear and some places to be blurry.
In order to obtain a better depth of field, the aperture is generally set to the minimum, and the scheimpflug lens can achieve clear imaging at extremely large apertures.
BOTE OPTICS scheimpflug lens series has a variety of models for you to choose from, and the scheimpflug lens can also be customized according to your needs.
