The ENVL-CL model is a product with two lightings: epi-illumination around the lens and transillumination on the box. The two lightings can be turned on/off individually.
The newly designed, LED-exclusive slim head uses a board-mounted LED with high color rendering (Ra≧90) and heat generation.
A flat, diffuser and protector will reduce the work and the light source as well as the glare unique to LEDs.
Epi-illumination can be used for external inspection, and transillumination can be used in to inspect the translucency of an object, its external parts, or fish-eye cameras as well as confirm the linings of a perforating hole.
