Long life, high power, lasers
Stabilized long-life high-power lasers, designed and manufactured by ZYGO.
ZYGO's Verifire™ interferometer system provides fast high-precision measurements of plano or spherical surfaces, and transmitted wavefront of optical systems and assemblies. Measure glass or plastic optical components – like flats, lenses, and prisms – and even precision machined metal and ceramic surfaces.

A true laser Fizeau design, the Verifire™ system expands upon ZYGO's unmatched experience in surface form metrology. The on-axis configuration combined with ZYGO's patented acquisition algorithms and full-featured Mx™ metrology software enables high-precision surface form metrology with advanced analysis capabilities.

SmartAveraging™ Technology

Measurement averaging is an effective method of reducing the effects of random noise sources such as air turbulence, but determining the best number of averages can be tricky... too few reduces the effectiveness; too many wastes time. SmartAveraging™ technology is an exclusive feature of ZYGO's Mx™ software that automatically calculates and uses the optimum number of averages. SmartAveraging technology removes guesswork, minimizes operator variability, and ensures confidence in the measurement result.

QPSI™ Vibration-Tolerant Interferometry

Enabled by optimized system design and a high-power laser, ZYGO's proprietary QPSI vibration-tolerant interferometry ensures reliable "ripple-free" phase measurements in vibration-prone environments, and can be trusted to provide accurate surface metrology in the QC lab and on the production floor.

Stabilized, Long-life, High-Power Laser

ZYGO's proprietary laser source is designed and manufactured in Middlefield, CT. The laser exceeds the power and lifetime of the commercially available HeNe lasers typically used in laser interferometer products. With a lifetime rating exceeding 60,000 hours, our laser is backed by an unmatched 3-year warranty, minimizing downtime and maximizing your ROI.

Accessories

The Verifire system is compatible with standard ZYGO interferometer accessories which expand the system's versatility. This includes our ZYGO certified reference optics that ensure optimum performance from our laser interferometers.
