Controllers are offered as fully enclosed instruments and as circuit cards.

Before selecting a controller, review the Electrical Drive Data page for the shutter model of interest. Recommended models are listed.

Each shutter has an optical rating that must be observed to avoid damage. Factors include rated wavelength (for dielectric mirrors) or range of wavelengths (for metal mirrors), CW maximum power, peak energy density (fluence), recommended beam diameter, polarization vector, and alignment control.

Shutters are designed for typical beams that use 50-80% of the aperture diameter. This allows good thermal dissipation on metal mirrors and keeps the damage threshold at a high level. When a small beam is to be used in a larger aperture, and the fluence or CW power is high, consult our sales engineer for estimated thresholds of optical damage.

Beams need to be aligned entering the input aperture to ensure the dumped energy is reflected to the proper location. Dielectric optics requires good alignment practice to provide the highest reflectivity and damage threshold. As a rule, the entering beam should be orthogonal to the input face within about 3 degrees.
