Player One M48M-M48M 2mm Adapter

Overview

The Player One M48M-M48M 2mm Adapter is a machined threaded coupler with M48×0.75 male threads on both ends, adding a fixed 2 mm to the optical path. It is a purely mechanical part with no glass and no electronics, made from aluminum 6061-T6.

Who It's For

This is a good match if you need to join two M48-female components back to back, or add a short, fixed 2 mm spacer to fine-tune backfocus within an M48 imaging train.

Key Features & Design

• M48 male on both sides: M48×0.75 male threads at each end.
• 2 mm optical length: adds a fixed 2 mm between the connected components.
• Aluminum 6061-T6 body: light, corrosion-resistant, and dimensionally stable.
• Fully mechanical: no optical elements and no electrical connection.

Recommended Uses

Use it to couple two M48-threaded accessories together or to add 2 mm of spacing where an M48 imaging train needs to reach a target backfocus.

Compatibility & Accessory Notes

The adapter fits standard M48×0.75 threads. Because it is a fixed-length coupler, include its 2 mm in your total backfocus calculation. If you are not sure how it fits your imaging train, send us your camera, filter, and spacer setup and we will work out the numbers with you.

Good to Know Before You Order

• Mechanical adapter only: it carries no optical elements and passes no electronic signal.
• Male on both sides: both ends are male threads, so the mating components need matching female threads.
• Fixed 2 mm length: the spacing it adds is set and not adjustable.

Frequently Asked Questions

Is it difficult to set up?

No — it threads directly onto standard M48 fittings by hand and needs no tools or adjustment.

What is it best used for?

Joining two M48 male-to-female junctions and adding a fixed 2 mm to the optical path.

Does it contain any optics?

No. It is a bare mechanical coupler with no lenses or coatings.

Will it change my backfocus?

Yes — it adds 2 mm, which you should include in your spacing total.

Bottom Line

In short: a compact aluminum M48 male-to-male coupler that adds a fixed 2 mm to the optical path, for cleanly joining M48 sections of an imaging train.
