(KL 300 Only) SCHOTT 121.101 Single Flexible Light Guide — 4.5mm / 600mm

The SCHOTT 121.101 is a single-branch flexible fiber optic light guide designed for the SCHOTT KL 300 light source. This shorter 600mm format is ideal when you want clean routing on a compact bench, minimal slack, and fast repositioning for stereo microscopy and inspection tasks.

Compatibility note: This item is listed as KL 300 Only. Confirm your light source model before ordering.

SCHOTT 121.101 Features
  • Compact reach (600mm): reduces excess slack for tidy bench setups
  • Flexible routing: route around fixtures, microscope stands, shields, and enclosures
  • Directional illumination: ideal for tuning contrast by changing angle and distance
Why teams choose a short single flexible guide
  • Less clutter: cleaner cable management versus 1000mm guides on small stations
  • Fast re-aiming: quick angle changes to reveal scratches, haze, chips, films, and texture
  • Stable workflows: easier to standardize distance and angle when the guide length matches the station

About the Manufacturer: 

SCHOTT is a multinational, technology-based group developing and manufacturing specialty glass, materials, and components used across microscopy, industrial inspection, electronics, and life-science workflows. In stereo microscopy illumination, SCHOTT’s KL ecosystem pairs compact light sources with modular light guides (flexible, gooseneck, and ringlight geometries) to help teams standardize lighting and improve repeatability.

The Technical Vault: SCHOTT 121.101 Single Flexible Light Guide (KL 300 Only)

Vault purpose: How to use a short flexible guide for contrast control, how to prevent setup drift, and how to avoid compatibility mistakes (KL 300 vs KL Series).

1) What the 121.101 is (and why 600mm matters)

The SCHOTT 121.101 is a single flexible fiber optic light guide listed as KL 300 Only with a 4.5mm diameter and 600mm length. :contentReference[oaicite:1]{index=1}

The shorter length helps reduce excess slack on compact inspection benches—often improving repeatability because the guide naturally stays within a narrower range of angles and distances.

2) The inspection lever: angle and distance (not just brightness)
  • Low-angle (“raking”) illumination: increases visibility of scratches, haze, edge chips, films, residue, and surface texture.
  • Higher angles: reduce harsh shadowing but can wash out fine texture.
  • Distance: controls hotspot size and glare; small changes can shift defect visibility.
3) Repeatability checklist (what to standardize)
  • Clock position: define the guide direction relative to the part (e.g., 1 o’clock).
  • Tip-to-part distance: define a target range and keep it consistent.
  • KL 300 output setpoint: record the brightness used for pass/fail decisions or documentation.
  • Support method: if your process is sensitive, use a simple clip/arm/fixture point so geometry doesn’t drift between operators.

Practical tip: Store a reference photo of the approved setup in the work instruction so the station can be reset quickly after cleaning or maintenance.

4) Compatibility guardrail (KL 300 vs KL Series)

This item is listed as KL 300 Only. :contentReference[oaicite:2]{index=2} If you are using KL 1500 / KL 1600 / KL 2500 (KL Series), choose KL-Series guides instead.
