TIR Collimators are an optic style that utilizes total internal reflection (TIR) to control the high angle light emitted by the lamp. Commonly these optics feature a convex feature in the center to control the light in the direct to low angles from the source. A TIR collimator has the ability to control the lamp's entire beam, making it a useful optic for applications where you need to limit field light or maximize peak intensity.
