General Photonics phase shifter produces phase shifts up to 15 pi at modulation frequencies from DC to 20 kHz.
OCT- und Sensorsysteme erfordern hochleistungsfähige ausgewogenePhotodetektoren, um das Signal-Rausch-Verhältnis des Systems zu verbessern. Die BPD-003 wurde speziell für OEM-Anwendungen in solchen Bereichen entwickelt, die auf niedrige Kosten und geringe Größe sowie hohe Leistung ausgelegt sind.
The FST-001-B is a piezo-driven fiber stretcher with a long optical delay range of up to 3 mm. The device comes complete with a piezo driver packaged in a user-friendly small enclosure.
GPCs’ 2nd generation all fiber phase shifter/modulator provides phase shifts up to 65π with a much lower half-wave voltage (~2 volts as compared with 10-20 volts for the 1st generation phase shifter) at frequencies from DC to 20 kHz
The FPS-003 all fiber phase shifter/modulator combines a wide modulation bandwidth (up to 60 kHz) with low half-wave voltages to create a long-range device that can be driven by standard function generators.
OCT and sensor systems require high performance balanced photodetectors to increase system signal to noise ratio. Polarization sensitive OCT and similar applications require separate analysis of the two polarization components of a signal. The PBPD-001 is specially designed for use in such systems.
Simultaneously detecting the powers of two orthogonal polarization components is important for many sensor and measurement applications. A pigtailed polarization beam splitter coupled with two photodetectors can be used for such applications; however, this arrangement is bulky, troublesome to handle, and costly.
