(KL Series) SCHOTT 155.100 Single Flexible Light Guide — Ø 5.0mm / 1000mm

The SCHOTT 155.100 is a single-branch flexible fiber optic light guide designed for SCHOTT KL-series light sources. It delivers directional illumination from a remote illuminator to the work zone, allowing operators to control angle and distance to tune contrast for microscopy and precision inspection.

Accessory note: This is a fiber-optic light guide. It does not generate light by itself and must be connected to a compatible SCHOTT KL-series light source.

SCHOTT 155.100 Features

Single-branch flexibility: easy aiming for localized, directional illumination
Larger Ø fiber: 5.0 mm diameter supports higher light throughput than smaller guides
M-PVC jacket: designed for routing and routine repositioning at inspection workstations
Standard KL interface: 10 mm adapter for KL-series light sources

Why teams choose a single flexible guide

Targeted contrast: adjust angle and distance to highlight scratches, haze, films, or edge features (application-dependent)
Remote illumination: keep the light source away from the immediate work envelope
Simple station builds: a single branch is often sufficient for focused inspection tasks

The Technical Vault: SCHOTT 155.100 Single Flexible Light Guide (Ø 5.0mm / 1000mm)

Vault purpose: How single-branch flexible illumination controls contrast, how to lock geometry for repeatability, and when a larger fiber diameter matters.

1) What the 155.100 is

The SCHOTT 155.100 is a single flexible fiber optic light guide for KL-series light sources. It delivers directional illumination to the inspection zone and is commonly selected when a single, controllable light vector is sufficient for the task.

2) Why Ø 5.0 mm matters

Compared with smaller-diameter guides, a 5.0 mm active fiber can deliver higher usable light output to the work surface. This can be beneficial when:

Working at longer distances from the part
Using lower-reflectivity materials
Needing higher brightness without increasing source intensity

3) Repeatability controls

Angle reference: record the guide’s clock position relative to the part
Tip-to-part distance: define and maintain a target range
Light-source setpoint: record output used for inspection decisions

Practical tip: Simple witness marks on the fixture and guide help operators reset approved geometry after cleaning or maintenance.

4) When to choose single vs dual vs ringlight

Single flexible (155.100): targeted, directional illumination with minimal hardware
Dual flexible: add a second branch for “rake + fill” contrast control
Ringlight: choose when uniform, low-shadow illumination is required

5) Source basis (spec traceability)
