Theia Varifocal Ultra Wide Lens 1.8-3.0 mm lens incorporates patented Linear Optical Technology® which enables an ultra-wide field of view without barrel distortion. It is a varifocal lens, which lets you optimize the field of view from wide angle to ultra-wide. The rectilinear design of the lens enhances the resolution at the edges of the image, increasing the probability of detection.The lens is IR-corrected. This means that you don't need to adjust the camera's focus when you shift between day and night mode using the IR-cut filter.
