    4D invites you to join us on Tuesday, January 10 for a webinar discussing surface roughness measurement on large optics.

    4D Technology's NanoCam Sq dynamic opitcal profiler being used to measure the surface roughness of a large optic

    Determining the roughness of large optics during polishing and after coating is challenging. Measuring optical grade roughness requires a high resolution metrology system such as an optical profiler. But typical optical profilers need extensive vibration isolation, and they lack sufficient clearance to measure large components. Inspectors must create replicas of portions of the large surface which can then be measured—a messy and time consuming process which provides only sparse data.

    A dynamic optical profiler is able to measure surface roughness across the entire surface of optics and precision surfaces. A dynamic system measures thousands of times faster than traditional profilers, making it possible to measure despite vibration, which enables handheld use, or mounting directly in polishing equipment.

    In this webinar we will discuss Dynamic Interferometry® technology and its advantages for non-contact measurement of large optical grade surfaces. We will show how a dynamic profiler can be used to measure on-optic or in situ in polishing equipment for vastly improved assessment of roughness before and after coating.

    The webinar will take place January 10 at 2:00pm Eastern Standard Time (19:00 GMT).

    Register today to learn about using dynamic optical profilers for measuring precision surfaces. The webinar will include a half-hour presentation followed by a question and answer period.

    Precision components for aerospace, automotive, and other applications must be inspected throughout production for damage, and throughout their life span for wear, corrosion and defects.

    Inspectors face challenges in determining the severity of defects and the depth of desired features such as laser marking or dot peening. Visual comparison techniques are quick and inexpensive but are subjective and not repeatable. More accurate metrology systems are typically too expensive, slow and susceptible to environmental factors for use on the shop floor.

    The 4D InSpec Surface Gauge is the first handheld, precision instrument for non-contact measurement of surface features and defects, with micrometer-level resolution. The gauge measures defects from 0.1 to 100 mils deep, even in difficult-to-access areas such as under flanges, in bores and on curved surfaces. Measurements take just seconds, with instant results and reporting.

    In this webinar we will discuss the Polarized Structured Light (PSL) technology behind the 4D InSpec Surface Gauge. We will demonstrate how the 4D InSpec can be used to measure surface features on large components and in difficult to access areas, as well as to make repeatable QA/QC measurements on production parts.

    The webinar will take place Thursday, Jan 19, 2017 1:00PM - 2:00PM EST (18:00 GMT).
