4D InSpec Options

Numerous options are available to increase productivity and ease of use with the 4D InSpec Surface Gauge:

Robotic Inspection

Robot Automation
Because our instrument is immune to vibration, it doesn't need to be handheld—it can be held by a robot! The software automatically adjusts for different material colors and reflectivity, making the automation of measurements painless.

The 4D InSpec software now natively supports UR robots, or your own robot. Automation speeds repetitive measurements, and provides high repeatability in measurement acquisition.

4D InSpec Fold Mirror Kit to measure surface defects in difficult to access areas
Fold Mirror Kit
The fold mirrors are used instead of the standard alignment aid to measure difficult-to-access areas, such as the sides of pipes, the surface between turbine blades, the area under a lip or flange, etc. The kit includes four mirrors:

• 20 mm left-hand fold
• 20 mm right-hand fold
• 12 mm left-hand fold
• 12 mm right-hand fold.

All fold mirrors are mounted at 45 degrees to bend the test beam 90 degrees. The standoff distance is set for full compatibility with the 4D InSpec. A hard shell carrying case is included.

Battery powered, wheeled cart

4D InSpec Surface Defect Gauge Cart with Monitor4D InSpec Surface Gauge measuring aircraft engine casing

The portable cart holds the all-in-one computer on a swivel arm, as well as the 4D InSpec and its stand on the adjustable shelf. Raise the monitor and shelf for standing use, or lower the monitor when measuring a part that is sitting on the floor. The articulated arm is easily positioned for use in tight quarters and to reduce glare in factory lighting conditions. The cart is also capable of securely holding the 500W power supply accessory.



4D InSpec Uninterruptable Power Supply
500W Portable Uninterruptable Power Supply (UPS)
This battery power supply is capable of running the 4D InSpec and computer for approximately 8 hours of standard use, or 6 hours of high-intensity use, without any need to plug into a wall outlet. The power supply provides improved portability for use throughout the shop floor. The power supply securely mounts to the LCD cart and detaches with a single thumbscrew. Multiple power supplies can be purchased so that one can be charging while the other is in use, allowing outlet-free operation of the 4D InSpec over multiple shifts.


4D InSpec Surface Gauge Depth Calibration StandardCalibration Standard
4D Technology worked with PTB and HALLE Präzisions-Kalibriernormale GmbH to create a depth standard for vertical calibration and verification of the 4D InSpec Surface Gauge. The standard includes grooves from 1 um to 900 µm deep. 4D uses the 50, 200, 600 and 900 µm grooves for 4D InSpec calibration. The geometry of the standards is shown here. Each standard comes complete with a storage box as shown.

The standard is made from very pure copper (OFHC-Cu) which provides the best surface qualities (arithmetical mean deviation Ra = 1 nm, waviness Wt = 50 nm, flatness 50 nm over 20 mm measurement length). The copper disks are 90 mm in diameter and 10 mm thick. After machining the disc with rotationally symmetrical grooves, wire EDM is used to cut the disk into twelve segments of equal size which are then chemically nickel-plated to a thickness of 5 µm. The surface hardness of the standards is then about 500 HV and wear-resistant.

The grooves in the uncalibrated standard are estimated to have uncertainties in their depths of about 200 nm. These standards will be measured at the factory using a 4D InSpec which was itself calibrated using a certified standard. The nominal groove depths will be noted upon shipment.

4D InSpec measurements can always be initiated using either the trigger button on the measurement head or the software controls on the touchscreen interface.

The USB foot pedal provides a third, hands-free option to initiate a measurement when measuring difficult geometries or large parts. All three methods are available at all times, providing maximum flexibility to easily achieve good surface defect measurements.

4D InSpec Depth Calibration StandardCalibration Standard with Height Certification
This standard is identical to that described above, except the four grooves used for 4D InSpec calibration are certified using the Carl Zeiss accreditation service, providing greater accuracy for 4D InSpec calibration. This standard is recommended for QC departments that require the highest accuracy standards. The uncertainty of the grooves will be:

• 50 µm groove = 80 nm
• 200 µm groove = 100 nm
• 600 µm groove = 100 nm
• 900 µm groove = 180 nm.

Stand-Alone Software License
4D InSpec Surface Gauge Feature Analysis for locating and measuring pits, scratches, bumps, corrosion and features
This option lets you install an additional copy of the 4D Inspec software on a computer which is not connected to the 4D InSpec instrument. The extra copy makes it possible to load, analyze and modify measurements from the instrument at the convenience of a separate Windows® 10-based computer, while the instrument continues to be used.

Remote Access Software
4D InSpec Surface Gauge remote access software enables WCF communication for integration into automated systems
This option enables Windows Communication Foundation (WCF) functionality with the 4D InSpec software such that the Surface Gauge may be controlled remotely via a user-written application. This functionality makes it possible, for example, to integrate the 4D InSpec into an automated platform. With the remote access software package you can trigger such actions as grabbing a live camera image, opening a configuration file, taking a measurement, performing the Feature Analysis calculations, or other key operations that normally happen via the 4D InSpec’s own graphical user interface.

IronPython Scripting
4D InSpec Surface Gauge Scripting with IronPython Optional Package
This option enable the IronPython Scripting language within the 4D InSpec software, allowing you to write your own data analyses and automation scripts. You can also manipulate the instrument or analyses using your own software to interact with the core 4D InSpec software. The package includes several example scripts to get help you get started and to demonstrate some of the additional capabilities.
