01 — Product Overview

Enovasense Point Sensor with T060 probe

Non-contact coating thickness measurement from 10 nm to 1 mm — with the smallest probe of the range

The Enovasense Point Sensor is a laser photothermal radiometry instrument that measures the thickness of a coating on a part — fully non-contact, fully non-destructive, in real time. The T060 probe is the ultra-compact head of our range: only Ø35 × 64 mm and 150 g, it is designed for applications where mechanical space is scarce — small robots, confined mechanical assemblies, dense multichannel arrays and integration into existing production tooling.

It measures paint, polymers, adhesives, anodizing, electroplating, thermal spray, cold spray, HVOF, PVD, CVD, PACVD, galvanizing, and screen-printing deposits on virtually any substrate — with the same thickness envelope as the rest of the range: from 10 nm up to 1 mm.

02 — Why choose the T060 point sensor

Six reasons this sensor earns its place on a production line

1. Non-contact, non-destructive, and substrate-agnostic

The sensor works by sending a modulated laser beam onto the coating and analysing the infrared thermal response with a built-in detector. No probe tip touches the part, so there is no risk of scratching a fresh paint layer or a soft polymer; and no sample is cut, so 100% of the production can be inspected instead of a destructive sample every thousand parts. The method is insensitive to the electrical or magnetic nature of the substrate — it works on metals, aluminium, steel, polymers, glass, and composites.

2. The most compact photothermal probe on the market

At Ø35 × 64 mm and only 150 g, the T060 is more than 60% smaller and 60% lighter than the T033 — and smaller than any competing photothermal or optical coating-thickness probe. It fits on the smallest cobots, reaches inside narrow fixtures and multi-part jigs, and can be doubled or tripled inside a single measurement station without mechanical interference.

3. One sensor covers an unusually wide thickness range

From a 10 nm PVD layer up to a 1 mm thermal spray deposit, a single T060 point sensor — configured with the right optical tool and the right laser module — covers the full envelope. This replaces the 2 or 3 complementary instruments typically needed when mixing eddy-current, ultrasonic, and X-ray gauges.

4. Real-time output, ready for closed-loop control

Each measurement takes from 100 ms to 1 s depending on the application. Results stream out in real time via Ethernet/TCP-IP and can be fed directly into an MES, an SPC system, or a closed-loop spray recipe. Coating process drift is caught in seconds, not in thousands of parts.

5. Proven in automotive, aerospace, medical, and electronics

The technology is deployed worldwide for critical coating measurements — including a joint patent with Renault Group (EP3781902B1) on the use of laser photothermal radiometry inside cylinder bores of combustion engines.

6. Engineered for safety and long service life

The laser source has a Mean Time To dangerous Failure (MTTFd) of 1454 years with a Diagnostic Coverage > 99%, and the controller integrates a safety interlock compatible with integration into a certified machine loop. The laser diode MTBF is 11.4 years in continuous use — these sensors run for years without maintenance beyond routine lens cleaning.

03 — Applications

Where the T060 point sensor is used

The T060 configuration is favoured whenever the measurement point is hard to reach, the machine footprint is tight, or several probes must be clustered into a small volume. Typical deployments include:

04 — Technology

How laser photothermal radiometry works

A modulated laser beam emitted by the module travels through the optical fiber to the probe, is focused on the coating surface and generates a controlled thermal wave inside the coating. An infrared detector inside the probe captures the returning heat wave and extracts two physical quantities from the signal: the phaseshift and the amplitude ratio between the thermal response and the laser modulation. The coating thickness is then derived from these signals through a calibration curve built on reference samples.

Why this technology — a summary

Photothermal radiometry is fully optical and thermal: no contact with the part, no electrical or magnetic coupling required. This means the sensor is indifferent to the magnetic properties of the substrate, to surface roughness (within a large range), to part geometry (flat, curved, internal bores) and to the production environment (dust, oil mist, fluid cooling — the front lens is protected and cleanable). Calibration is built from representative reference samples once, and then reused in production indefinitely.

All values are typical. The actual performance depends on the combination of items selected (module power, optical tool, fiber length) and on the target application. Please contact Enovasense for a performance diagnosis on your specific samples.

06 — Product Structure

A modular sensor — six items to build the system you need

The Point Sensor is structured as a set of six independent articles (plus an optional control station), giving full configuration flexibility. A complete working sensor requires one item from each of the six categories below. For a multichannel system, items 2 to 6 must be ordered in the same quantities as the number of measurement channels.

Upgrade without replacing. Each item is ordered by a dedicated reference code. You can upgrade a laser power, change a spot size, replace a damaged fiber or extend to a multichannel configuration without replacing the rest of the system.

07 — Available Articles for a T060 Configuration

Full list of references compatible with the T060 probe

① Controller & software suite

One controller is required per system. Choose the size according to the number of channels.

② Module (laser + signal acquisition)

Select one module per measurement channel. The choice of wavelength and power depends on the coating material and thickness range.

The maximum power of a laser source may vary by up to 30 % below the nominal value.

③ Probe — T060

④ Optical tool — T060 (front lens / lens + mirror)

The optical tool defines the spot size on the part and the working distance between the probe and the part. Tools come in three families: simple front lens (screwed or magnetic), Mirror + Lens (90° horizontal emission) and Lens + Mirror (inverted geometry). All references below are compatible with the T060 probe.

Working-distance column gives the nominal focal configuration of the lens. For Lens + Mirror tools, the effective distance from the tool's exit aperture to the sample is shorter than the nominal value. Tolerances on the measurement distance range from ±0.5 mm (metallic/ceramic, 20 mm working distance) up to ±20 mm (paints/polymers, 150 mm working distance) depending on the optical tool and the coating family. Long-working-distance objectives (80 / 200 / 450 mm) are exclusive to the T033 probe.

⑤ Optical fiber — T060 (FC/PC ↔ SMA)

All T060 fibers are multimode 105 µm core with an FC/PC connector on the module side and an SMA connector on the probe side.

⑥ Electric cable — T060 (M8)

One cable per probe. The T060 probe uses an M8 connector on the probe side.

08 — Accessories and options

A number of complementary accessories are available to extend the sensor capability in specific contexts:

Note: the lens and sample air-blowing systems (5105900, 5105901), the dynamic 90° module (5104781), the probe rotation module (5105929) and the long-working-distance objectives (80 / 200 / 450 mm, refs 5105899 / 5105897) are exclusive to the T033 and are not compatible with the T060.

09 — Optional Integration

From sensor to turnkey control station

The T060 Point Sensor can be integrated into one of four Enovasense control stations. These stations include a safe enclosure, an automated positioning system, a PC and a dedicated HMI — turning the raw sensor into a turnkey laboratory, by-the-line or in-line measurement solution. The sensor itself must be ordered separately from the station.

Need help building a configuration? The T060 probe is compatible with every Enovasense module, with all T060-specific optical tools and with every control station. Contact Enovasense with the description of your coating and substrate, your thickness range and your production throughput — we will propose the optimal combination of the six items and, if needed, the appropriate control station.
