Pen torches are typically made of durable plastic or metal and have a small, lightweight design that makes them easy to carry in a pocket or medical bag. Pen torches typically have a single LED bulb that provides a bright, focused beam of light. Many pen torches also have a pupil gauge, which is a small ruler that is used to measure the diameter of the pupil.
