High density collimators, approximately 1.5" diameter x 1.875" length, are machined from solid tungsten bars, suppling 3 to 5 half value layer (HVL) of shielding for IR 192. Customer machined to fit standard source tubes. Beam collimators have an 82 degree cone window that eliminates film cut off, even on short source to film distances.
Large diameter beam and End Port Collimators are made as special orders. Sketch must be provided with your request. Typical delivery is 2 to 3 weeks.
Mini Collimator Clamps are designed to fit 1.5" diameters. Made of 0.062" stainless spring steel with slotted ears, to accommodate a 6 ft. web belt (included), for securing to the pipe. Longer belts are available for additional charge.
