Nikon features an upgraded LC15Dx non-contact laser scanner that provides continuous feedback on metering information

The LC15Dx laser scanner, manufactured by Nikon Metrology Industrial Metrology Business Unit (Brighton, Michigan, USA), is the global benchmark for the efficient measurement and detection of manufactured components, especially those with complex free-form geometry, such as turbine blades, orthopedic implants and complex plastic parts. Compatible with all metering platforms and software, new versions of the sensor have been rolled out, and Nikon says its features have been significantly upgraded in several key areas to make it more suitable for Quality 4.0 detection applications.

LC15Dx has been certified to ISO 10360-8, the industry standard for the performance of laser scanning equipment for coordinate measuring machines (CMM). The "ISO 15-10 Detection Size Error All" on the device is reported to be one-third better than previous models, providing more accurate and repeatable size measurements at the 10 micron scale than the original 15 micron.

Custom-designed, in-house manufactured scanner lenses offer improvements in the way data captured by the lens and imager is converted into measured data points, with improved structural resolution for finer surface textures and details.

The LC15Dx uses Nikon's proprietary software algorithm to maintain scanning accuracy, speed and data quality by automatically adjusting the laser Settings in real time at each measurement point to match the type and reflectivity of the material being tested. Coupled with advanced daylight filters adapted to different ambient light conditions, they are said to be able to examine any material, regardless of color, gloss or transparency, without spraying or other surface treatments. This capability is further enhanced in the new unit by facilitating better data acquisition from very dark materials. You can even turn on high ISO mode for black surfaces, including those with glossy surfaces.

In addition, Nikon reported faster scanning capabilities when turned on, increasing productivity when detecting or reverse-engineering components. Its warm-up time is still zero because the algorithm compensates for any measurements taken when the sensor temperature rises to match its ambient temperature. However, the new feature is to halve the startup time to 14 seconds, so the internal computers are ready to receive data faster.

According to product manager Kristof Peeters, "In addition to all these improvements, the livery has been changed to a smart black and white look, so users can immediately see that they are using the latest sensor version. The LC15Dx retrofit kit is available for controllers installed on all leading brands of CMMS, while many reputable software providers offer a wealth of programming and reporting options.

In addition to these developments, Nikon's laser-scanning models are completely wireless, so they can be adapted for a variety of applications, whether mounted on production machines or suitable for metering equipment. Contactless scanners are said to transmit the dense point cloud data they collect almost in real time over WiFi links, while maintaining the high data throughput, consistency and accuracy of a wired connection. The operation of the detection tool can also be combined with the contact detection of the multi-sensor measurement program on the CMM, using the automated option of the replacement rack so that deep holes or other hard-to-see interior features can be accessed by touching the probe to trigger.

Peters added: "Our new wireless scanning technology is well suited to support process quality control in machining centers and 3D printers, eliminating the time-consuming process of bringing components to a quality control room for inspection, which effectively eliminates the need for measurement data to be fed back into production.
