Target Precision Analyzer - TPA
From uncertainty to certainty — in under two minutes.
The Chrosziel TPA turns riflescope inspection into a fully digital, objective, and repeatable process. It replaces subjective assessments with standardized measurement workflows — delivering fast, reliable results every time.
Whether in R&D, production, or quality control, the TPA measures key optical parameters like diopter, parallax, magnification, reticle alignment and field of view — all digitally, all without operator influence. Data is visualized in real time and exported instantly into professional test reports. The result: less ambiguity, more trust, and higher product confidence — from prototype to final delivery.
- Measure what matters – digitally, reliably, instantly: The TPA delivers automated readings of all relevant optical parameters, eliminating human error and streamlining inspections.
- Create professional test reports in seconds: PDF and CSV exports document each test session — ideal for quality audits, incoming goods inspection, or OEM compliance.
- Same result. Every time. No matter who’s testing: Standardized digital workflows ensure repeatability across users, locations, and shifts — from single pieces to batch runs.
- Built for production. Trusted by OEMs. Scalable across teams: The TPA integrates seamlessly into high-throughput environments — minimizing training time, maximizing reliability.
Product Information
Product Overview
The Chrosziel TPA is a compact, self-contained measurement system for riflescopes. It combines motorized collimator alignment, digital chart calibration, and guided software workflow into a single, highly efficient solution. Unlike traditional optical benches or visual methods, the TPA delivers reproducible data with zero guesswork — fully digital, objective, and documented.
It is the perfect fit for optics manufacturers, service departments, military armorers, and anyone needing to verify optical performance with confidence.
Measurement Functions
Precision that goes beyond expectations.
The TPA tests all essential riflescope parameters — in a digital, structured and time-saving workflow:
Magnification
Measures the true zoom factor — digitally and precisely.Zero Diopter Check
Confirms optically neutral eyepiece alignment.Field of View
Calculates the full usable viewing field at any magnification.Parallax Evaluation
Analyzes image shift and pupil deviation to quantify parallax — fully digital.Reticle Angle
Detects misalignment of the reticle relative to the mechanical center.Cleanliness Assistance
Supports visual inspection of lenses for contamination, scratches or residue.
