The LCM-100 can perform far-field measurement of light distribution exiting a fiber. This analysis can yield the numerical aperture of a fiber. The far-field measurement can also be used to verify proper launch conditions for military standard launches such as AS100 orAS62 specified in ARP5061. |
- LCM-100
Launch Condition Meter
•Far-field measurements
•Auto-alignment and focusing
•Mode Field Diameter measurements

Description
The LCM Launch Condition Meter is a convenient benchtop instrument for analyzing characteristics and geometry of optical fibers. Use Santec's software to scan and easily plot far-field patterns. The LCM can be equipped with two internal LEDs with 850 nm and 1300 nm wavelengths. Internal 105/125µm, 0.22NA fiber allows for overfill testing in most applications. The optical interface of the instrument accepts all standard 2.5mm ferrules. Other connector sizes are available upon request.
Applications
•Fiber analysis
•Insertion loss source compliance testing
•R&D
Compliance
•IEC 60793-1-45 for MFD
Using the auto alignment and focusing feature of the LCM-100 system, a technician can easily verify that the system is properly focused and aligned to yield accurate and repeatible nearfield measurements.
Using the far-field scanning apparatus of the LCM-100 system, the mode field diameter can be measured for single-mode fibers per the reference method as defined in IEC 60793-1-45.
