CRi Spatial Light Modulator

Simultaneous phase and amplitude modulation of your VIS or NIR beam with no moving parts. These Spatial Light Modulators (SLMs) are based on proven industry-leading designs, and offer both single-mask and dual-mask configurations for phase, amplitude, or for simultaneous phase/amplitude pulse shaping. The Cambridge Research & Instrumentation (CRi) Spatial Light Modulators (SLMs) are now a part of Meadowlark Optics. CRi collaborated with the Massachusetts Institute of Technology (MIT) on the...

ACPL-798J Sigma-Delta Modulator

The ACPL-798J is a 1-bit, second-order sigma-delta modulator that oversamples an analog input signal into a high-speed data stream with galvanic isolation based on optical coupling technology. The ACPL-798J operates from a 5V power supply with dynamic range of 82dB with an appropriate digital filter. The differential inputs of ±200mV (full scale ±320mV) are ideal for direct connection to shunt resistors or other low-level signal sources in applications such as motor phase current...

Automotive R²Coupler™ Sigma-Delta Modulator

The ACPL-C797T isolated modulator converts a low bandwidth analog input into a high speed 1-bit data stream by means of Sigma-Delta ( Σ- Δ)  over-sampling modulator.   The  modulator data and on-chip sampling  clock are encoded and transmitted across the isolation  barrier where they are recovered and decoded into separate high speed clock and data channels.  Combined with superior optical coupling technology, the modulator delivers high noise margin...
