FAQs
What is the Excelitas 35-00-04-000?
It is a 1.67x \ 120fl lower lens for the Optem FUSION micro-inspection lens system, made by Excelitas Technologies in the Optem series. It is a lens accessory that serves as one of the stackable modules used to configure the magnification, function, form, and wavelength of the lens system.
How is total magnification calculated in the FUSION system?
With the Optem FUSION System, the optical magnification is the product of the magnification of the lower lens, the zoom dial setting (if a zoom is used), and the magnification of the camera tube. This 1.67x lower lens contributes its factor to that overall calculation for the configured system.
What wavelengths does the FUSION system support?
The formula works even when using Qioptiq microscope objectives, which can be modified to affect form, function, and performance across the visible (400-700 nm), near infrared (NIR, 700-1100 nm), and short-wave infrared (SWIR, 900-1700 nm) wavebands, supporting varied imaging and inspection needs.
How do I choose the right configuration?
Refer to the FUSION Component Matrix and the Optical Performance Chart that matches your chosen fixed magnification or zoom configuration, for example, with or without objectives and with standard or mini camera tubes. Following the flow lines identifies the components required to configure the lens performance you desire.
What is this lower lens used with?
It is designed for use with the Optem® Fusion Micro-Inspection Lens System. As a modular lower lens, it stacks with other FUSION modules such as a zoom and a camera tube to build the complete imaging path, rather than functioning as a standalone lens on its own.
