PRODUCT DETAILS
Ultra‑stable parallel beam for laboratory‑grade accuracy – The F550‑3S Laser Collimator Small Screen features a 550mm focal‑length optical system that generates a highly stable, collimated laser beam simulating an infinite‑distance target. This enables precise verification of collimation axis error (2C), vertical index error (i‑angle), and horizontal axis tilt error in total stations and electronic theodolites.
Triple‑tube configuration for multi‑axis calibration – Equipped with three parallel optical tubes, the F550‑3S Laser Collimator allows simultaneous or sequential alignment along multiple axes. This design eliminates frequent repositioning of the instrument under test, greatly improving calibration efficiency and enabling comprehensive diagnostic testing.
Floor‑standing design for maximum mechanical stability – Unlike benchtop units, the F550‑3S Laser Collimator adopts a heavy‑duty floor‑style structure that minimises vibration and external disturbances. Even during prolonged calibration sessions, it ensures consistent optical alignment and repeatable measurement results.

Integrated photoelectric tube with real‑time display – One of the three tubes incorporates a photoelectric sensor and a small built‑in display, providing instant visual feedback during alignment. This feature enhances measurement sensitivity and makes the calibration process more intuitive and efficient.
Wide compatibility – one instrument, multiple applications – The F550‑3S Laser Collimator is compatible with total stations, electronic theodolites, automatic optical levels, multi‑line lasers, and rotary laser levels. It serves as a universal calibration solution for metrology labs, service centres, and manufacturing QC departments.
