LINZA 150 Spectrophotometer for Lenses and Lens Assemblies
Spectrophotometers For Optical Coatings
LINZA 150 UV-VIS-NIR Spectrophotometer
LINZA 150 is the world only spectrophotometer designed for unattended measurement of transmittance and reflectance of lenses and multi-lens assemblies.
Description
The LINZA 150 spectrophotometer is designed for broadband transmittance and reflectance measurement of lenses and lens assemblies (objectives), adding a whole new dimension to your optical metrology capabilities.
Indeed, lenses come in vast variety of sizes and shapes which makes them extremely difficult to measure. Given the inherent challenges in measuring transmittance or reflectance on lenses, optical engineers often need to combine data from a several witness samples in order to tease out basic details about optical performance of a lens. However, due to the nature of any deposition technology, the coating on lenses differs from that on the witness sample. Even more insurmountable barrier is the need to measure the off-axis performance of the optical lens .
With LINZA 150, you get transmission data on axis and reflection data at any point of the lens surface, fully unattended. This ensures that only perfect lenses with perfect coatings are delivered to customers and approved for lens assemblies. This valuable data also helps our customers to backward analyze and improve their deposition technology.
LINZA 150 Spectrophotometer is also a great instrument for your QA/QC lab ensuring that lenses from your supplier do meet your specs. The instrument is perfectly suited for both routine lens measurements and sophisticated improvement of lens coating technology.
Features
The following product features are found only in LINZA 150 Spectrophotometers and help our customers measure the coatings on lenses and lens assemblies successfully:
- Fast on-axis transmittance measurement of individual convex/concave lenses
- Fast on-axis transmittance measurement of lens assemblies (objectives) with maximum objective length of 240,0 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
