Fiber optic light guides are a key component of efficient UV curing because they transfer UV and visible energy from the light source installed inside the point curing device to the curing area. This blog will outline several factors to consider when choosing a light guide for your system.

DIMESIONS

The optical guide is usually one meter long, but if your application requires a more customized length, a variety of other lengths are available.

Nanjing Giant can provide greater curing capacity due to its larger light conduction opening which captures more light from the bulb.

MULTI OR SINGLE POLE? 

Light which is emitted from spot lamps can be channelled through a single pole light guide or split between multiple pole light guides. Each pole of a multi-pole light guide emits equal intensity (typically +/- 10% for liquid filled light guides), and are available liquid-filled or quartz fibre with all sharing a common shutter. Standard Giant multi-pole lightguides incorporate integrating rods to cure multiple points simultaneously with a more balanced output from pole to pole. On the other hand, single pole light guides offer a higher minimum initial intensity (W/cm²) and typical intensity at 2000 hours(W/cm²), ensuring light is delivered with much greater strength and depth to the target object.

INTENSITY V DISTANCE

When the curing area/intensity is considered in relation to distance, the UV and visible light emitted from the photo conduction are separate. Therefore, as the distance from the end of the light guide increases, the strength decreases and the curing area increases.

Giants has various glass fiber optic light guides and quartz fiber optic light guides. They can be used in industrial and medical area. Such as laser television, laser sensor, dental curing light, fiber optic patch cord, etc. Most of our fiber optic light guide products are customized. Clients need to provide sample or drawing before making. Nanjing Giant will give customer some professional advise to help customer get the final design.
