CCS LDR2-LA

LED dark field illumination

By mounting LEDs on a flexible circuit board at a steep angle, it becomes possible to converge light in the centre section from a low angle. Providing direct light from a low angle to the centre section creates an image that emphasises the workpiece's surface characteristics.

The LDR2-LA series has a compact design and a low housing height. All housings are made of aluminium, which ensures effective heat dissipation. Diffusers and polarisers are available as an option with some models. The LDR2-LA series is a low angle illumination series and has multi-row LEDs. Multi-row dark field solutions use a shallower angle of 65° to 80° to the optical axis. These lights are also available as a WD version. They work most effectively at working distances of between 5 mm to 20 mm.

LDR2-LA Optional diffuser ring: By using a diffusion ring, glare from shiny surfaces can be effectively suppressed as is shown in the image below.

Inspection of uneven damage or engravings

Providing direct light from a low angle to the centre section creates an image that emphasises the workpiece's surface characteristics.

Aluminium housing

Heat dissipation material is used between the board and the aluminium housing, absorbing heat produced by the LEDs. This succeeds in greatly reducing the creation of heat, which causes the LEDs to deteriorate.

Available with diffusion plates

Diffusion plates can prevent glare, which is a problem when creating images of glossy workpieces.
