Photo Electronics DROLED UV LED lamps have different optical systems, depending on the specific use.

FLAT WINDOW

It permits to achieve an high exposure time in the curing phase.

The radiation comes out with a wide angulation, equal to about 120°.

Application

Complete polymerization few millimetres from the window.

Available on DROLED models
L70, L74, L75, L76

FOCUSED LENS

It permits to focus the radiation at high distances and obtain ­an high irradiance value, using the light ­reflection and refraction optical principles. This specific system also avoids the dispersion of the energy on the sides of the radiation.

APPLICATION

Complete polymerization far from the window of irregular or non-planar surfaces.

Available on DROLED model
L70

ROD LENS

Ideal for collimate the radiation that comes out from ­the cylindrical ­­surface, achieving a very tight beam,­a consequent low exposure time ­and a reduction ­in rays dispersions outside the target area.

APPLICATION

­­Gelification and ink pinning.

Available on DROLED models
L75, L76

ANGLED ROD LENS

Ideal for collimate the radiation that comes out from the cylindrical surface,­achieving a very tight beam, a consequent low exposure time and a ­reduction in rays dispersions outside the target area.

The outbound light ­is angled compared to the lamp axis and that permit to distance the target­­ ­area from the printhead.

APPLICATION

Gelification and ink pinning through angled beam.

Available on DROLED models

L75, L76

DISTANCE BETWEEN UV LED LAMP AND THE SURFACE TO POLYMERIZE

DROLED UV LED lamps allow to move the emitting window away from the surface to be polymerized, still obtaining a high radiant energy.
