SCHOTT A08575 Dual Rigid Gooseneck 23" Fiber Optic “Focusing” Light Guide (Black)

The SCHOTT A08575 is a dual (2-branch) semi-rigid gooseneck fiber optic light guide with permanently attached focusing spot lenses. It is designed for incident illumination in space-constrained microscopy and inspection setups where you want two independently aimable light vectors and the ability to focus the beam at the work surface.

Compatibility note: Compatible with SCHOTT ACE and DCR Series light sources (A20990 / A20980) and not compatible with KL Series. Confirm your light source family before ordering.

SCHOTT A08575 Features
  • Made with black dekabon semi-rigid gooseneck tubing
  • Standard output ferrules accept spot lenses with or without polarizing caps
  • Dual focusing gooseneck with permanently attached spot lenses — focus by turning the knurled lens barrel(s)
  • Incident illumination for space-constrained applications
Why teams choose the A08575
  • Precise positioning: complete control of light placement for contrast tuning
  • Near shadow-free options: opposing gooseneck positions can reduce harsh shadowing
  • Re-adjust with ease: reposition quickly when switching parts, fixtures, or inspection steps
  • Two lights, one source: dual branches illuminate the workspace from a single illuminator
  • Beam control: focusing lenses help concentrate or expand the hotspot on the target surface

About the Manufacturer: 

SCHOTT is a multinational technology group known for specialty glass, advanced materials, and precision components used in microscopy, industrial inspection, electronics, and life-science workflows. SCHOTT’s modular illumination ecosystem pairs dedicated light sources with interchangeable light guides (goosenecks, flexible guides, and ringlights) so teams can standardize illumination geometry, improve operator consistency, and maintain repeatable inspection conditions.

Notes: For consistent results, document the gooseneck angles (“clock positions”), tip-to-part distance, and light-source output setting used during evaluation. If you change focus, record the lens barrel position used for pass/fail decisions.

The Technical Vault: SCHOTT A08575 Dual “Focusing” Gooseneck Light Guide (23" / Black)

Vault purpose: How to use dual gooseneck + focusing optics to control contrast, how to standardize geometry for repeatable inspection, and how to avoid the #1 error (ACE/DCR vs KL compatibility).

1) What the A08575 is (and what makes it “focusing”)

The SCHOTT A08575 is a dual rigid gooseneck fiber optic light guide with permanently attached spot lenses. These spot lenses are focused by turning the knurled lens barrel(s), allowing you to tighten the hotspot for high-contrast defect detection or widen coverage for general viewing.

This product is listed as compatible with ACE and DCR Series light sources (A20990 / A20980) and not with KL Series.

2) The winning setup: “rake + fill” (dual-branch advantage)
  • Raking branch: set one branch low to the surface to amplify scratches, chips, haze, films, residue, and texture.
  • Fill branch: set the second branch higher to soften harsh shadows and stabilize exposure.
  • Opposed geometry: placing branches in opposing positions can create near shadow-free illumination on complex parts.
3) Focus as a controlled input (don’t let it drift)

The focusing barrels are powerful because they change the illumination footprint. For inspection programs, treat focus as a controlled parameter:

  • Hotspot size: smaller hotspots can increase contrast for tiny defects (and also increase glare risk).
  • Coverage: wider focus reduces hotspots and improves uniformity for documentation images.
  • Repeatability: once qualified, record the barrel position (or number of turns from a reference) used for pass/fail decisions.
4) Standardization checklist (what to document)
  • Branch clock positions: define directions relative to the part/fixture (example: 10 o’clock + 2 o’clock).
  • Tip-to-part distance: define a target range and maintain it.
  • Focus setting: record focusing barrel position used for the approved method.
  • Light-source setpoint: record intensity level used for evaluation and documentation.
  • Reference image: store a baseline for glare/contrast and use it after maintenance or re-training.

Practical tip: A simple witness mark on each gooseneck + fixture makes “reset to approved geometry” fast after cleaning.

5) Compatibility guardrail (avoid the most common ordering error)

The #1 error is mixing SCHOTT families. This product is listed as ACE/DCR compatible and not for KL Series. If you are using KL-series sources (KL 1500 / KL 1600 / KL 2500), choose KL-series dual guides instead (example: (KL Series) SCHOTT 154.202 Double Rigid Gooseneck Light Guide).

6) Published dimensions (bench meaning)
  • 23" (584 mm) gooseneck length: reach around stages/fixtures while keeping the source remote.
  • 12 mm tubing diameter: contributes to “set-and-stay” stability once positioned.
  • 8 mm distal ferrule: output-end mechanical interface noted on the product page.
  • 5 mm active input fiber: input fiber diameter noted on the product page.
7) Source basis (spec traceability)
