Trinocular Microscope Barlow Lens 0.5X WD165 & 0.7X WD120

Trinocular Stereo Microscope Barlow Objective Lens — 0.5X (WD165) & 0.7X (WD120)

Expand the capabilities of your trinocular stereo microscope with this precision-engineered Barlow auxiliary objective lens. Available in two magnification options — 0.5X (WD165 mm working distance) and 0.7X (WD120 mm working distance) — this lens accessory is designed to alter your microscope's total magnification range while simultaneously extending or adjusting the working distance between the lens and the specimen. It's the ideal upgrade for hobbyists, researchers, electronics technicians, and educators who need greater flexibility from their existing stereo or trinocular microscope setup.

Key Features

• Two Magnification Options: Choose 0.5X for a lower magnification with increased field of view and extended working distance (WD165 mm), or 0.7X for a moderate reduction with WD120 mm working distance — giving you more room to maneuver samples or tools under the lens.
• Trinocular Camera Port Compatible: Specifically designed for trinocular stereo microscopes, making it equally useful for the camera port (for imaging/video capture) or main observation ports.
• Auxiliary Objective Lens Design: Threads directly onto the existing objective of compatible stereo zoom microscopes for quick, tool-free installation.
• Zoom Stereo Microscope Compatible: Works with standard zoom stereo microscopes using common objective thread sizes.
• Enhanced Field of View: The 0.5X Barlow significantly widens the observable area, ideal for inspecting larger circuit boards, specimens, or intricate craft work.
• Optical Glass Construction: High-quality optical glass elements deliver clear, sharp imagery with minimal chromatic aberration.
• Compact & Lightweight: Easy to attach and remove, with no impact on your microscope's overall ergonomics.

Frequently Asked Questions

Q: What does a Barlow auxiliary objective lens do on a trinocular microscope?

A: A Barlow auxiliary objective lens threads onto your microscope's existing objective to modify the total magnification. A 0.5X Barlow halves the base magnification while doubling the working distance (WD165 mm), giving you a wider field of view and more room to work under the lens. A 0.7X Barlow reduces magnification to 70% of the base while providing a WD120 mm working distance — a great balance between magnification and specimen access.

Q: Which Barlow lens option should I choose — 0.5X (WD165) or 0.7X (WD120)?

A: Choose the 0.5X (WD165) if you need a wider field of view and maximum working distance — perfect for larger samples or where you need to use tools simultaneously (e.g. soldering, dissection). Choose the 0.7X (WD120) if you want a moderate working distance increase while retaining higher magnification — suitable for detailed observation tasks where the sample is relatively compact.

Q: Is this Barlow lens compatible with my stereo zoom microscope?

A: This lens is designed for trinocular and stereo zoom microscopes that accept auxiliary objective lens attachments. It is compatible with most standard stereo zoom microscopes. We recommend verifying your microscope's objective thread size and front lens diameter before purchasing to ensure a proper fit.

Q: Can this lens be used on the camera port of a trinocular microscope?

A: Yes. This Barlow objective lens is suitable for use on the trinocular camera port, allowing you to adjust the image magnification captured by your microscope camera — useful for achieving full-frame coverage or optimal image scale for documentation and imaging purposes.
