Waveplates and retarders are optical components designed to transmit light while modifying its polarization state without attenuating, deviating, or displacing the beam.

Innovative ultra-thin filters provide flexibility, scratch resistance, and durability comparable to most hard oxide coatings. Learn more at Edmund Optics.

Optical Filters are used to selectively transmit or block certain wavelengths or wavelength ranges within optical systems.

Pulse Compression and Dispersion Compensation for Ultrafast Lasers

Learn about the metrology that Edmund Optics® uses to guarantee the quality of all optical components and assemblies.

Dispersion is the dependence of the phase velocity or phase delay of light on another parameter, such as wavelength, propagation mode, or polarization.

Learn how Highly-Dispersive Mirrors compensate for dispersion and compress pulse duration in ultrafast laser systems, which is critical for maximizing performance.

Four major trending topics in machine vision technology include edge artificial intelligence (edge AI), AI paired with high-resolution sensors, event-based machine vision, and affordability of SWIR sensor technology.

Polarizers are optical components designed to filter, modify, or analyze the various polarization states of light.

Hyperspectral imaging (HSI) and multispectral imaging (MSI) are two related technologies that make use of specialized vision systems to acquire extra image information from extended regions of the electromagnetic spectrum aside from the visible spectrum.

The short pulse durations of ultrafast lasers make them interact with optical components differently, impacting the optic’s laser damage threshold.

Specialized coatings can minimize thermal lensing in ultrafast laser systems, which are particularly susceptible to detrimental thermal effects.
