- Fast on-axis transmittance measurement of individual convex/concave lenses
- Fast on-axis transmittance measurement of lens assemblies (objectives) with maximum objective length of 240 mm
- Unattended on-axis and off-axis reflectance measurement of individual lenses providing measurement data virtually from any area on lens surface (both convex and concave). Ideal for fine-tuning of deposition technology used to produce coatings on lenses
