Resonant Chopper Systems
Electro-Optical Products Corp.
An external clock signal, to provide an ultra stable modulating optical beam motion [sub] system. The system can be used as a "stand alone" unit, in the laboratory, or can be incorporated into a larger instrument/system. The chopper is ONE FIXED FREQUENCY, picked from the range of 5 Hz to 20 kHz. The chopper is a small size, light weigh, low cost and long life device. It requires low power drive electronics and does not radiate electromagnetic interference (EMI). It has high frequency stability and high amplitude stability. The chopper is IR, VIS and UV and high vacuum capable. Reference signal and position output available.

*Divergent Light Measurement
The IS1.5-VIS-FPD-800 & IS1.5-IRG-FPD-800 contain 2 photodiodes: a calibrated photodiode for precise power measurement using Ophir meters and a fast photodiode with integral reverse bias circuit for temporal characterization using third-party instrumentation such as oscilloscopes and spectrum analyzers. Their small, 1.5" internal diameter preserves the temporal shape of pulses down to 3.5 nsec for VIS and 6 nsec for IRG. An SMA fiber optic connector is provided for connection to a spectrometer. The large, 20 mm input aperture allows for wide acceptance angles and long working distances, making these spheres well suited for testing VCSELs and other types of laser.

Mode-Conditioned Light Sources
Thorlabs' Mode-Conditioned Light Sources are fiber-coupled LED sources that have an output with a flat-top profile in the far field. Common applications include the testing of multimode fused fiber components as well as verification of modal behavior in fiber-based setups. Standard fiber-coupled LED sources can have a range of output profiles that are usually not uniform and vary from source to source. This can be dependent on emitter orientation, alignment with fiber tip, and connector assembly...show more -
