Handheld Light Source
The palm-sized FibKey 6900-series light source pairs with the 6800-series power meter for a full range of tests.
Features:
Energy saving: uses the same low-power technology as the 6800 series Highly stable output power and wavelength Portable: playing-card size, fits a shirt pocket, only 126 g Two-color molded housing integrates a shock-absorbing layer: sturdy, protective, stylish, and comfortable Outputs stable continuous wave (CW) or modulated (MOD) light MOD frequency selectable: 270/1000/2000 Hz Calibrated stable output: −7 dBm (laser) 0 dBm laser output available on request High-quality laser diodes and precision microelectronic circuitry ensure time and temperature stability Waterproof touch keys Tri-color LED indicates CW/MOD output and 270 Hz/1 kHz/2 kHz modulation Low-battery LED flashes; still works 2–5 h until fully drained User-controlled auto power-off (eco mode) Multiple wavelengths: 650/850/1310/1550 nm, etc.
