The VF20 cleave check interferometer
The VF20 is an interferometric inspection system specifically designed for testing optical fiber cleaves. The VF20 will check the surface quality and flatness of your cleaved, polished or lensed fiber end at the flick of a switch.
Based on the Michelson interferometer, the VF20 benefits from a long working distance, thus eliminating the risk of damage to the fiber end. The user can select either an inspection mode, to view the quality of the fiber end, or an interferometric mode, to characterize the surface flatness.
The VF20 is able to measure the quality of both perpendicular and angled fiber ends using removable precision fiber holders.
Features and benefits
- Non-contact - no damage to the fiber under test
- Inspection and interferometric modes
- Easy to use - load fibers using kinematic fiber holder
- Measure perpendicular and angled fiber ends
Applications
- Cleaver manufacture or maintenance
- Laser manufacture
- Fiber R&D - holey fiber, MEMs devices, etc.
The VF20 "Trio"
The Trio is the latest in the VF-20 range. It is designed to produce high quality images of the ends of optical fibers to enable you to estimate their quality and flatness.
The VF20 Trio will enable you to inspect fibers with diameters from 100um to 1000um, so you won't need multiple pieces of equipment to see all your fiber types properly.
It has two modes of operation – inspect and fringe - so you can check the flatness and the end quality of your cleaved, polished or lensed fiber end at the flick of a switch. This means reduced testing time.
It comes with an efficient software package which enables you to grab, save, and print images. This gives you the ability to record vital data and produce QA reports for internal use or to supply to customers.
The VF20 "Classic"
If you are working exclusively with 125 µm diameter fibers, the VF-20 Classic is for you. It is designed to have a native magnification which produces high quality images of the ends of Telecom type fibers to enable you to estimate their quality and flatness. So when you have inspected your fibers with the VF-20 Classic you can be confident that they have the standard of end preparation which will maintain the reliability and performance of your product.
The VF-20 Classic comes with the same software package as the VF-20 Trio which enables you to grab, save, and print images, and as well as estimate end angles.
