What is the minimum focusing distance and field depth of the CAL32 optical level?

The minimum focusing distance of the CAL32 optical level is 1 meter, which allows precise measurements even in confined or urban environments. Its field depth (depth of field) permits clear sights between 1 meter and infinity, ensuring sharp readings across job sites.

Technical Insights on the CAL32 Optical Level's Focusing Distance and Field Depth

The CAL32 optical level is recognized among professionals for its robust surveying capabilities. The minimum focusing distance—1 meter—means users can reliably target benchmarks and reference points even at close range. This feature becomes particularly significant on congested construction sites or urban landscaping projects, ensuring uninterrupted workflow.

The field depth of the CAL32, meaning the span where objects remain acceptably sharp, extends from the minimum focus to several hundred meters. For example, when calibrating or verifying elevation differences, this generous depth of field reduces the need for constant refocusing, which is critical for maintaining accuracy over long distances. For comparison, other instruments available in our surveying equipment selection offer similar performance, but the CAL32 stands out for its ease of use and consistent results.

For large-scale leveling projects in Belgium, tools like the Topcon RLH5A rotating laser pack can complement optical levels by providing automated large-area grading solutions, but precise manual sighting with the CAL32 remains indispensable for detailed benchmarks or starting points.

How does field depth affect accuracy with the CAL32?

The field depth ensures that both the staff and reference marks remain focused across varying distances, reducing human error due to refocusing and contributing to consistently reliable readings in all site conditions.
