FOIF Diagonal Eyepiece

Diagonal Eyepiece for FOIF Surveying Instruments

The FOIF Diagonal Eyepiece is an optical accessory for compatible FOIF total stations and theodolites. It provides an angled viewing position when the instrument telescope is directed toward elevated targets or steep vertical angles.

For surveyors using FOIF instruments in construction, engineering and industrial measurement projects, a suitable diagonal eyepiece makes telescope observations more convenient when direct viewing is difficult.

A Useful Accessory for FOIF Instrument Users

FOIF surveying instruments are used for a variety of measurement tasks, from construction layout to angular observations and engineering control surveys.

A diagonal eyepiece is particularly useful when the telescope must be aimed upward toward structural reference points, elevated equipment or overhead survey targets.

Instead of requiring the operator to view directly through the standard eyepiece position, the accessory provides an alternative optical viewing arrangement.

This improves observation convenience without changing the instrument's measurement accuracy.

Selecting the Correct FOIF Eyepiece

FOIF produces different total station and theodolite series, and their eyepiece connections should not be assumed to be identical.

Before purchasing, confirm the instrument model and the required eyepiece mounting arrangement.

For replacement orders, buyers can provide the original accessory reference or photographs of the telescope eyepiece connection to help identify a suitable configuration.
