Brand: ThorLabs | Category: Scientific & Laboratory Equipment

Shear plate devices that give a quick qualitative check of whether a coherent beam is collimated. Fringes parallel to the reference line mean the beam is collimated, and rotated fringes show convergence or divergence.

Sensors that pair a CMOS camera with a photolithographic microlens array to measure the wavefront of a beam and decompose it into Zernike terms. They are used for optical alignment, adaptive optics and lens testing.
Confocal cavity spectrum analysers that resolve the fine structure of a continuous wave laser, including mode hops and linewidth. A piezo scans the cavity length and the transmitted signal is read on an oscilloscope.
Dual scanning slit heads that reconstruct the two dimensional intensity profile of a near Gaussian beam, with a knife edge mode for very small spots. They measure beam width and position to ISO 11146 for continuous wave and pulsed lasers.
