Precision and Innovation Since 1973
The Chrosziel TPA sets a new benchmark in objective
optical testing. Delivering standardized results in under
two minutes – for manufacturers, authorities, and
professionals who demand precision
About Chrosziel
50 Years of Bavarian Precision
For over five decades, Chrosziel has set the standard for precision in film and
broadcast equipment. With the TPA, we bring this legacy to the optics industry –
combining proven engineering with cutting-edge innovation to deliver
reproducible results in under two minutes.
BENEFITS
All You Need. In One System. Without Compromise.
Fast & Digital
Complete testing in under two
minutes – fully digital, efficient,
and documented.
Fully Objective Results
No more guesswork. The TPA
delivers fully standardized and
reproducible test data.
Ready to Use
Preconfigured and ready within
minutes – with guided setup and
intuitive operation.
All in One Solution
One standardized solution – all
parameters, no modular setup,
no complexity.
Portable & Flexible
Designed for mobile use – easily
deployed in labs, production
lines or service departments.
Audit-Ready Documentation
All results are exportable, timestamped
and ready for traceable documentation
and compliance.
TRUSTED PRECISION
Proven results, delivered digitally.
Measurements
Where Precision Becomes Data.
Magnification
Determines true optical magnification – digitally
and precisely.
Zero Diopter Check
Verifies correct zero-diopter setting for optically
neutral alignment.
Field of View
Calculates the full usable field of view – across all
zoom ranges.
Parallax Measurement
Measures parallax using sharpness shift and exit
pupil deviation.
Reticle Angle Measurement
Checks reticle rotation relative to the scope’s
mechanical reference.
Cleanliness Check
Supports visual inspection of optical surfaces for
dust or residue.
True precision starts with proof.
A perfect image is not enough. In critical situations, optical performance must be
proven – not assumed. That’s why we built the TPA: to turn invisible tolerances into
measurable data. To give manufacturers confidence, authorities certainty, and
professionals the peace of mind they deserve. Objective. Repeatable. Trusted.
FLEXIBILITY
One System. All Diameters.
Every scope deserves precision – regardless of size.
The TPA is equipped with quick-change mounts for all major tube diameters.
Switching between scopes takes just seconds – no tools, no adjustments, no
compromises. Engineered for professionals, built for universal compatibility.
