(KL 300 Only) SCHOTT 171.101 Single Flexible Light Guide — M-PVC Ø 4.5mm / 1000mm

The SCHOTT 171.101 is a single-branch flexible fiber optic light guide designed for SCHOTT KL 300 light sources. It delivers targeted illumination from a remote illuminator to the work zone—ideal for microscopy and precision inspection tasks where you want adjustable angle, controlled beam placement, and remote illumination.

Accessory note: This is a light guide (fiber optic). It does not generate light by itself and must be connected to a compatible KL 300 light source.

SCHOTT 171.101 Features

Flexible light guide format (available in different lengths and diameters across the family)
M-PVC outer jacket for handling and routing at a workstation
Designed for remote illumination from a KL 300 light source

SCHOTT 171.101 Benefits

High flexibility: supports multiple illumination techniques and easy aiming
Remote illumination: keep the light source away from the immediate work zone while delivering light where needed
Controlled contrast: position the guide to create raking light that can reveal scratches, haze, films, or edge features (application-dependent)

Common System Pairing

About the Manufacturer:

SCHOTT is a multinational, technology-based group developing and manufacturing special glass, specialty materials, components, and systems for more than 125 years. In illumination workflows, SCHOTT’s modular approach pairs dedicated light sources with interchangeable light guides so teams can standardize lighting geometry and maintain repeatable inspection conditions. :contentReference[oaicite:1]{index=1}

Notes: If you’re selecting between single vs dual guides, start with the inspection task: single for targeted spot lighting; dual when you need “rake + fill” contrast control.

The Technical Vault: SCHOTT 171.101 Single Flexible Light Guide (KL 300 Only)

Vault purpose: How to use single-branch flexible illumination to control contrast, how to keep station results repeatable, and how to avoid the two most common failures: “washed out” vs “too harsh.”

1) What the 171.101 is (in station terms)

The SCHOTT 171.101 is a single flexible fiber optic light guide specified for KL 300 only. Its job is to deliver light from the KL 300 to the inspection zone while letting the operator set angle, distance, and incidence to control how defects appear. :contentReference[oaicite:2]{index=2}

2) The “contrast lever”: angle beats brightness

For most surface inspections, changing the incidence angle changes visibility more than increasing brightness:

Low-angle (raking) light: emphasizes texture, scratches, chips, haze, films, and residues.
High-angle light: reduces shadows and can “flatten” texture—useful for general viewing or documentation photos.

3) Repeatability checklist (what to lock down)

If your team reviews parts across shifts, treat illumination geometry as a controlled input:

Tip-to-part distance: define a target range and keep it consistent.
Angle reference: record the “clock position” of the guide relative to the part (e.g., 2 o’clock).
Intensity setpoint: record the KL 300 output setting used for pass/fail judgments.

Fast control tip: Add a small witness mark on the fixture and a corresponding mark on the guide’s sheath so approved geometry can be reset after cleaning.

4) Size and routing: why Ø 4.5 mm and 1000 mm matter

Ø 4.5 mm: a common “precision aiming” diameter—small enough for tight work envelopes while still delivering useful output.
1000 mm length: supports routing from a remote light source to microscope/inspection stations without crowding the work area.
M-PVC jacketing: designed for handling and routine repositioning at a workstation. :contentReference[oaicite:3]{index=3}

5) Single vs dual: when you should upgrade

Single (171.101): best for targeted spot illumination and quick angle changes.
Dual flexible: best when you need “rake + fill” (one branch for defect emphasis, one branch to stabilize exposure).

KL 300 dual option: SCHOTT 171.202 Double Flexible Light Guide 4.5mm/1000mm.
