What does the Incure LGT-90-8 do?

The Incure LGT-90-8 mounts onto the tip of any Ø8mm UV lightguide and redirects its UV output 90° relative to the lightguide axis. This provides a wider Ø8mm spot at a right angle — curing larger perpendicular bond faces on housing side walls, wide PCB edge flanges, and vertical assembly surfaces that a straight lightguide cannot reach without repositioning the part.

When should I use the LGT-90-8 vs the LGT-90-5?

Use the Incure LGT-90-8 when your lightguide has a Ø8mm exit port and the bond face is wide enough to benefit from the larger spot. The LGT-90-5 is for Ø5mm lightguide systems requiring a precision spot at 90°. The LGT-90-8 covers larger bond joint areas in one pass, eliminating the need for multiple Ø5mm spot positions across a wider face.

Which lightguides is the LGT-90-8 compatible with?

The Incure LGT-90-8 is compatible with any UV spot curing lightguide with a Ø8mm exit port, including the Incure LLG-1P-8 liquid light guide and compatible third-party liquid light guide systems with a matching Ø8mm aperture. Verify your lightguide exit port diameter before ordering.

Does the LGT-90-8 reduce UV intensity?

The Incure LGT-90-8 aperture matches the Ø8mm lightguide core diameter — there is no aperture step-down at the connection interface. The aluminum body is rated for continuous UV exposure. Any intensity reduction is a function of the lightguide and UV source, not the terminator itself.

When should I use the LGT-90-8 vs the LGT-60-8?

Use the Incure LGT-90-8 when the bond face is exactly perpendicular to your lightguide approach axis — a full right-angle (90°) exit is needed. Use the Incure LGT-60-8 when a full 90° approach is mechanically obstructed by the fixture or housing and an oblique 60° angle provides the necessary clearance to reach the bond face.

90° Lightguide Terminator — Incure LGT-90-8

Name: Incure LGT-90-8 90° Lightguide Terminator
Brand: Incure

Incure LGT-90-8 mounts onto the tip of any Ø8mm UV spot curing lightguide and redirects its output 90° — curing wider perpendicular bond faces, side-wall flanges, and large PCB edge joints that the Ø5mm LGT-90-5 cannot cover in a single pass.

Covers Wider Bond Faces Than the LGT-90-5 in One Pass

The LGT-90-5 delivers a Ø5mm spot at 90°. The LGT-90-8 delivers the same right-angle access with a Ø8mm spot — covering larger bond joint areas on vertical housing walls, wide PCB edge connectors, and side-wall flanges without repositioning. Where the LGT-90-5 requires multiple spot passes across a wider face, the LGT-90-8 cures in one.

No Aperture Adapter at the Ø8mm Lightguide Port

Inserting a Ø5mm terminator on a Ø8mm lightguide port creates a step-down at the connection interface that wastes UV energy. The LGT-90-8 matches the Ø8mm core exactly — full throughput at the tip, no adapters, no energy loss through the terminator. For Ø8mm systems already in the process, no hardware changes are needed.

Ø8mm Aperture — Wider Spot for Larger Bond Joint Areas

The LGT-90-8 aperture matches the Ø8mm lightguide core with no step-down — the full Ø8mm output exits at 90°. Aluminum body is rated for continuous high-intensity UV exposure. For precision Ø5mm perpendicular access, see LGT-90-5. For oblique 60° access at Ø8mm, see LGT-60-8.

The Incure LGT-90-8 is compatible with any UV spot curing lightguide with a Ø8mm exit port. Verify your lightguide exit port diameter before ordering; aperture mismatch will cause UV energy loss at the connection interface. For precision Ø5mm perpendicular access, see LGT-90-5. For oblique-angle Ø8mm access, see LGT-60-8.
