CM3005 Multi-Angle Spectrophotometer — 5 angles for metallic and effect finishes

The CM3005 multi-angle spectrophotometer (COLO product code PRO7922) measures the colour of metallic, pearlescent and other special-effect finishes at 5 angles in one measurement, with 1 receiver (45°). It is a handheld, battery-powered instrument for the car body, the paint shop, the production line and the laboratory.

Overview

Place the instrument on the panel and press the button: all 5 angles are measured in about 5 s and shown in one table on the touch screen, with the colour difference to the standard at every angle and a pass/fail result.

Key characteristics

• 5 measuring angles in one measurement, 1 receiver (45°)
• Concave grating and 256-pixel dual-array CMOS sensor, 400–700 nm in 10 nm steps, 0–600 % reflectance
• Full-spectrum LED with blue enhancement
• Repeatability ΔE*ab 0.03, inter-instrument agreement 0.2 ΔE*00
• Flop index and colour difference at every angle
• Colour camera preview, 3.5″ touch screen, USB and Bluetooth 5.0, battery operation

Suitable for

• Automotive OEM coatings: body colours, bumpers, mirror caps and other add-on parts matched to the body
• Refinish and body repair: the repair colour checked against the original paint at every angle
• Paint and effect-pigment producers: aluminium, mica and interference pigments in development and incoming inspection
• Coated plastics and consumer goods with metallic or pearlescent finish

Why multi-angle

A metallic or pearlescent coating does not have one colour: near the gloss angle it is light and saturated, at the face angle it shows its main colour, and at a flat angle (the flop) it turns darker or changes hue. Two panels can match at 45° and still look different on the car. A multi-angle instrument measures every angle the standard prescribes, so a mismatch is found before the parts are assembled. The CM3005 measures the five angles used in the ASTM and DIN methods for metallic finishes.

Measuring and data

All 5 angles are measured with one press of the button; the camera preview shows where the instrument sits on the part. The instrument keeps 1 000 standards and 4 000 samples and transfers data by USB or Bluetooth 5.0; the PC software is available for download.

Which model in the series?

All models share the same handheld body, concave-grating optics with a 256-pixel CMOS array, 400–700 nm, 0–600 % reflectance, camera preview and a 3.5″ touch screen. They differ in the number of angles and receivers and in the effect values:

• CM3003 — routine check of metallic colours: near-specular, face and flop angle.
• CM3005 — the five angles of the ASTM and DIN methods for metallic finishes, for paint shops and suppliers of add-on parts.
• CM3006 — six angles plus sparkle grade, coarseness and colour variation, when the effect pigment itself must be controlled.
• CM3008 — adds a 15° receiver for pearlescent and interference pigments.
• CM3012 — twelve angles with two receivers for development laboratories and OEM colour approval.
