Foresters commonly use these prisms to measure the basal area factor (BAF) of trees. They feature a glass construction, which is either clear or amber tinted. Amber prisms provide a brighter image, which can aid in visibility during conditions with little sunlight. Our prisms are available in several different Basal Area Factors (BAF).
