The resolution of an SLM refers to its ability to distinguish between two close light points, typically measured in pixels or micrometers. Spatial Light Modulators (SLMs) are versatile optical devices that modulate the intensity, phase, or polarization of light waves in space and time. A simple example is an overhead projector transparency. It is the best qualified and diversified SLM platform with many versions optimized for specific requirements, including high reflectivity versions featuring a dielectric mirror for high power applications. Our SLMs consist of liquid crystal (LC) pixels, each independently addressed, acting as separate variable retarders.
[pdf] The transmissive spatial light modulator uses electrically addressed thin-film transistor driven liquid crystal display (TFT-LCD), while the reflective spatial light modulator uses silicon-based liquid crystal display (LCOS-LCD). Schematic of a liquid crystal-based Spatial Light Modulator. Liquid crystals are birefringent, so applying a voltage to the cell changes the effective refractive index seen by the incident wave, and thus the phase retardation of the reflected wave. The use of LC. Our high-power SLMs are recommended for these applications. They play an important role in adaptive optics as phase-correction devices.
[pdf] A beam splitter or beamsplitter is an optical device that splits a beam of light into a transmitted and a reflected beam. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. Image Credit:. Beamsplitters are optical components designed to divide or combine light beams within an optical system.
[pdf] The Visual Fault Locator (VFL) Pen has a visible red light source centered on 650nm. The RPEN-210 is a necessity tool that should not be missing from any fiber plant manager or fiber optic installing technician. VFLs typically use a 650nm wavelength red laser that is transmitted through the fiber.
[pdf] Fiber optic transmitters convert electrical signals into optical signals and then inject these optical signals into light- conducting cable. They use light emitting diodes (LED) or laser diodes as their optical source, and are designed for use with either single-mode or multi-mode. The four main types of optical sources are LEDs, Fabry-Perot (FP) lasers, Distributed Feedback (DFB) lasers, and Vertical Cavity Surface-Emitting Lasers (VCSELs). LEDs are tiny semiconductor devices. Fiber-optic communication systems require a light source to generate the signal that the fiber transmits.
