Test & Measurement

Designs and manufactures dynamic laser interferometers and optical profilers, and surface defect gauges. Applications include precision machined surfaces, optics, astronomy, aerospace, space-based telescopes, flexible electronics, automotive, and in-line production measurement.

Extensive suite of application-focused instrumentation for life sciences and materials research and production covers the full range of metrology techniques, sample sizes, and imaging resolutions. Technologies include AFMs, NanoIR spectrometers, fluorescence microscopes, stylus and optical profilers, mechanical testers, and nano-indenters.

Develops integrated imaging solutions to enable automated visual inspection and measurement of light, color, and surfaces. Scientific-grade imaging colorimeters are used for production-quality inspection and R&D testing of displays, backlit components, LEDs, and other light sources, as well as overall manufacturing integrity.

Provides measurement solutions for optical surfaces and systems. Custom metrology for measuring surface figure error, precision alignment, and transmitted wavefront error. Products include computer-generated holograms (CGHs) for interferometric measurement of aspheric and freeform surfaces, mechanics, and accessories for enabling CGH measurements.

Precision optical glass: strip, blanks, pressings, polished balls, near-UV transmitting i-Line glass, ceramic substrates, CaF2, UV/IR materials, quartz, fused silica (standard/excimer grade), Nanoceram. Ohara CCZ ultralow expansion (excellent CTE uniformity, blank form, to 1.8 m diam). Double-side polished substrates (low surface roughness, excellent flatness).

Fizeau and LUPI interferometers. Making optics is a daily challenge. Less time, more challenging specifications, and demands to lower cost. Apre interferometers give you the performance edge and architecture to grow with you, at minimal cost. APRE upgrades most brands and models of interferometers to keep your present systems working.
