Diffraction Grating

Diffraction grating is an optical component with a periodic structure that diffracts light into several beams travelling in different directions . The emerging coloration is a form of structural coloration. The directions or diffraction angles of these beams depend on the wave (light) incident angle to the diffraction grating, the spacing or distance between adjacent diffracting elements on the grating, and the wavelength of the incident light.

Beam Splitters

A beam splitter is an optical device that splits a beam of light in two. It is a crucial part of many optical experimental and measurement systems, such as interferometers

Optical Chopper System and
Chopper Wheels

The MC2000B Optical Chopper is a precision instrument that utilizes advanced features to modulate light from a continuous beam. The controller uses a phase-locked loop (PLL) motor speed control design to precisely maintain the chopping speed and phase relative to a reference signal. An internal, crystal-stabilized, frequency synthesizer provides an accurate and stable reference frequency for stable long-term performance. The MC2000B Chopper offers faster locking times, interface improvements, and a larger selection of blades than our previous-generation MC2000 Optical Chopper.

Compact Spectrometer, 350 - 700 nm

An optical spectrometer is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. The variable measured is most often the light's intensity but could also, for instance, be the polarization state. The independent variable is usually the wavelength of the light or a unit directly proportional to the photon energy, such as reciprocal centimeters or electron volts, which has a reciprocal relationship to wavelength

Compact Spectrometer, 500 - 1000 nm

Thorlabs' Czerny-Turner spectrometers are fiber-based, compact devices roughly the same size as a portable hard drive. Each spectrometer is calibrated using the included patch cable

Laser Line Mirrors

Optical Element - Laser line mirrors are fabricated with specialized coatings that offer high damage thresholds, making them well suited for use with a range of high-powered CW or pulsed laser sources / high-intensity beams typically produced by Nd:YAG, Ar-Ion, Kr-Ion, and CO2 lasers.
