LINZA Family of Spectrophotometers for Lenses

Measuring real lenses is fundamentally different from measuring coated flats. The LINZA series was engineered for this task — enabling accurate reflectance and transmittance measurements directly on curved surfaces, from single lenses to entire optical assemblies.

It ensures that your production or R&D verification reflects the actual optical performance of the finished product.

LINZA 150
185-1700 nm

When your optics are curved, LINZA 150 provides true on-part measurement of lenses, doublets, and assemblies. It captures transmittance and reflectance across broad spectral ranges — no need for witness flats or approximations. Designed for coating verification directly on the real component, it brings confidence into optical manufacturing QA.

LINZA 2752
2.5-5.2 µm

Built for the MWIR (2.5–5.2 µm) range, LINZA 2752 precisely measures transmission through real lenses and multi-element systems. It enables accurate evaluation of coatings and substrates on actual curved optics, not just reference samples. Perfect for QA and R&D of IR imaging and sensor optics.
