Wavelength Meter

HighFinesse provides sensitive and compact wavelength meters with a wide spectral range for high-speed laser measurements. The optical unit is a photodiode array transmitted by a temperature controlled Fizeau based interferometer. High absolute accuracy is achieved through the use of solid-state, non moving optics. The optical unit and related electronic products are placed in a compact, thermal sleeve. Connect a computer or laptop through a high-speed USB 2.0 port, which allows for high data read rates. The analysis software displays all interferometer information and is compatible with Microsoft Windows.

Main features and advantages:

·Pulse and continuous wave lasers can be measured

·The most accurate instrument: Measurement resolution of ± 2 MHz, 500KHz

·High speed measurement up to 600 Hz

·Very wide spectral range: 192 nm -11 µ m

·Data control is achieved through simple API access

·(Virtual Instruments, C++, MathLab...)
