SCHOTT A08500 Dual Rigid Gooseneck 18" Fiber Optic Light Guide (Chrome)

The SCHOTT A08500 is a dual (2-branch) semi-rigid gooseneck fiber optic light guide that delivers precise, directed incident illumination for microscopy and inspection workstations. Dual goosenecks allow you to aim two light vectors independently—commonly used as “rake + fill” to reveal surface features while controlling shadowing.

Compatibility note: Compatible with SCHOTT ACE and DCR Series light sources (A20990 / A20980). Verify your light source family before ordering.

SCHOTT A08500 Features

Made with chrome plated semi-rigid metal
Standard output ferrules accept spot lenses with or without polarizing caps
Incident illumination for space-constrained microscopy/inspection workstations

SCHOTT A08500 Advantages

Precise positioning: complete control of light placement
Near shadow-free illumination: opposing gooseneck positions can reduce harsh shadowing
Re-adjust with ease: fast re-aiming when switching parts, fixtures, or inspection steps
Two lights, one source: dual models illuminate the workspace with a single light source

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.

The Technical Vault: SCHOTT A08500 Dual Gooseneck Light Guide (18" / Chrome)

Vault purpose: How dual-gooseneck geometry shapes contrast, how to standardize illumination for repeatable inspection, and what the published dimensions mean at the bench.

1) What the A08500 is

The SCHOTT A08500 is a dual (2-branch) semi-rigid gooseneck fiber optic light guide listed as compatible with ACE and DCR Series (A20990 / A20980). Each branch is 18" (457 mm) long, allowing two independently aimable light vectors for incident illumination.

2) The default best practice: “rake + fill”

Raking branch: set one branch low to the surface to reveal scratches, haze, edge chips, films, residue, and texture.
Fill branch: set the second branch higher to soften shadowing and stabilize exposure.
Opposed branches: placing legs in opposing positions can create near shadow-free illumination (as noted on the product page).

3) Repeatability checklist (what to standardize)

Branch clock positions: define each branch direction relative to the part/fixture (e.g., 10 o’clock + 2 o’clock).
Tip-to-part distance: define a target range and keep it consistent.
Light-source setpoint: record intensity used for evaluation and documentation images.
Reference image: store a baseline for glare/contrast and use it after maintenance or training.

Practical tip: Add witness marks on the fixture and use a quick photo in the work instruction so operators can re-set the “approved geometry” in seconds.

4) What the published dimensions mean at the bench

18" (457 mm) branch length: compact reach for bench-top work without excess routing.
12 mm tubing diameter: supports “set-and-stay” aiming once positioned.
Distal ferrule Ø 8 mm: output-end interface noted on the product page; standard ferrules accept spot lenses with/without polarizing caps.
Active input fiber Ø 10 mm: input bundle diameter noted on the product page.
Chrome tubing: durable, cleanable finish often preferred in instrument-heavy work cells.

5) Quick accessory note (spot lenses & polarization)

The A08500 uses standard output ferrules that accept spot lenses and optionally polarizing caps (as listed on the product page). Spot lenses can tighten the beam for higher-contrast viewing on small areas, while polarization is commonly used to reduce glare on reflective surfaces (application dependent).
