MANUFACTURING PRECISION OPTICS FOR FAST,
GROUND-BASED INVENTORIES OF FOREST BIOMASS & VOLUME.

GLOBALLY APPLICABLE WEDGE PRISMS

Wide BAF of 1-30 m2/ha applies to all global forest types and also enables “big BAF” height measure (VBAR) at 3x diameter measure (TC) of 1-10 m2/ha. The “big BAF” method is the world’s most time-efficient method to measure forest biomass and volume1. Amber tinted wedge prisms (available in 1-10 BAF metric) heighten contrast in low-light conditions in any forest type.

MODERN Wedge PRISM LENSES (Pat. Pend.)

Aluminum tubes shaped for eye sockets, clear labels, protective caps, and cases with lanyards allow anyone to conduct prism sweeps from plot center without push or pull positioning errors, BAF size errors, glass chipping, or equipment losses. Prism lenses are also compatible with all smartphone or tablet camera lenses via included clips. Off-set tree stem images can be viewed via digital grids to more easily view “in” or “out” status. Furthermore, off-set images can be digitally photographed for auditors, supervisors, and others.
