Vorion Scientific M54Mx0.75mm to M36Fx1mm Adapter-3mm Added Thickness

Vorion Scientific M54x0.75 Male to M36x1 Female Adapter – 3mm Added Thickness

Precision Thread Conversion for Astronomy and Astrophotography Equipment

The Vorion Scientific M54x0.75 Male to M36x1 Female Adapter is a specialized astronomical mechanical adapter designed to connect equipment featuring different metric thread standards while introducing only 3mm of nominal additional axial spacing.

Featuring an M54x0.75 male external thread and an M36x1.0 female internal thread, the adapter allows compatible telescope components, optical accessories and camera assemblies to be integrated into a single threaded mechanical system.

In astrophotography, maintaining a suitable mechanical distance between the telescope optics and camera sensor is important, especially when using spacing-sensitive field flatteners, focal reducers and other correctors.

This Vorion Scientific adapter provides a compact thread conversion solution for custom imaging configurations where the required M54 and M36 interfaces differ in both diameter and thread pitch.

Key Features

• M54x0.75 Male Connection: External male threading with a nominal diameter of 54mm and a thread pitch of 0.75mm.
• M36x1.0 Female Connection: Internal female threading with a nominal diameter of 36mm and a thread pitch of 1.0mm.
• 3mm Added Thickness: Provides a nominal 3mm axial extension for compatible threaded assemblies.
• Thread Diameter and Pitch Conversion: Provides the mechanical transition between two different metric thread standards.
• Compact Fixed-Length Design: Suitable for configurations where minimizing additional mechanical spacing is important.
• Astrophotography Integration: Can be used in compatible telescope imaging trains, camera adapter assemblies and optical instrumentation.
• No Optical Components: A passive mechanical adapter with no lenses, mirrors or optical coatings.
• No Power Requirement: Requires no electrical connection, external power supply or software.
• Made in India: Vorion Scientific branded astronomy accessory with India as the country of origin.

Purpose of the M54 to M36 Thread Adapter

Modern astronomy and astrophotography equipment uses several mechanical thread standards, depending on the telescope, imaging accessory and manufacturer.

Larger threaded interfaces such as M54x0.75 are frequently used in astronomical imaging systems, while other specialized optical components may use smaller threads such as M36x1.

Because these connections differ in both nominal diameter and pitch, they cannot be connected directly.

The Vorion Scientific M54 Male to M36 Female Adapter provides an interface between compatible components using these two standards.

Its compact 3mm added-spacing design can be particularly useful when the imaging system has a limited available mechanical spacing budget.

Understanding the Thread Specifications

The adapter includes two different metric threads:

• M54x0.75 Male: 54mm nominal thread diameter with 0.75mm thread pitch.
• M36x1.0 Female: 36mm nominal thread diameter with 1.0mm thread pitch.

Thread pitch represents the axial distance between adjacent thread crests. Therefore, the 0.75mm and 1.0mm pitches are not interchangeable.

Before purchasing, users should verify the complete threaded specification of both mating components, including diameter, pitch, connection orientation, thread engagement and available clearance.

3mm Added Thickness and Backfocus

Many astronomical imaging systems include a series of mechanical components between the telescope optics and the camera sensor. These can include threaded adapters, filter wheels, off-axis guiders, filter drawers and camera mounting accessories.

Each component may contribute to the total mechanical spacing of the imaging train. For optical systems equipped with a field flattener or focal reducer, the correct sensor distance is determined by the manufacturer's optical specifications.

The Vorion Scientific M54 to M36 adapter is designated to introduce a nominal 3mm of additional thickness.

For example, if an existing imaging assembly provides 52mm of spacing and an additional 3mm is required, the adapter may contribute to achieving a nominal total of 55mm, provided both threaded connections are mechanically compatible.

Important: The 55mm example is illustrative. Actual backfocus requirements, reference surfaces and tolerances depend on the specific optical system.

Technical Specifications

Applications in Astronomy and Astrophotography

1. Telescope Imaging Train Integration

Allows compatible M54 female and M36 male-threaded astronomical components to be connected in a customized telescope imaging assembly.

2. Camera Adapter Configurations

Can be used in camera adapter systems where the required mechanical connections correspond to the specified M54x0.75 and M36x1.0 threads.

3. Backfocus-Sensitive Optical Systems

Useful when a compact thread conversion interface is required and the assembly can accommodate the nominal 3mm extension.

4. Telescope Optical Accessories

Provides a mechanical connection option for suitable telescope accessories, including specialized optical adapters and compatible threaded components.

5. Scientific and Laboratory Imaging

May be incorporated into custom scientific imaging and optical instrumentation requiring these particular thread standards.

Compatibility Information

The adapter requires the following mating connections:

• M54x0.75 Female: To receive the adapter's M54 male thread.
• M36x1.0 Male: To connect to the adapter's M36 female thread.

Compatibility Warning: This adapter is not interchangeable with M36x0.75, M42x0.75, M48x0.75 or other thread standards.

Matching the nominal thread diameter without matching the pitch can result in incorrect engagement and damage to the threaded components.

Compatibility must also be checked for mechanical clearance, available thread depth and the required imaging-train spacing.

Installation Guidelines

1. Identify the M54x0.75 female connection in the intended assembly.
2. Identify the component with the corresponding M36x1.0 male thread.
3. Verify both thread dimensions and pitches.
4. Confirm adequate thread depth and mechanical clearance.
5. Carefully engage the M54 male side with the compatible female connection.
6. Install the M36 male-threaded accessory into the adapter's female side.
7. Hand-tighten carefully without excessive force.
8. Confirm mechanical stability and adequate support for the attached equipment.
9. For imaging applications, verify the completed optical-axis spacing.

Frequently Asked Questions

What does this adapter convert?

It connects an M36x1.0 male-threaded component to an M54x0.75 female-threaded interface.

Does this adapter add 3mm of backfocus?

The adapter is specified as adding 3mm of nominal mechanical spacing. The effective installed distance should be evaluated between the relevant reference surfaces of the connected equipment.

Will it fit an M36x0.75 thread?

No. The adapter's female connection is specified as M36x1.0. An M36x0.75 thread has a different pitch and must not be forced into the adapter.

Does it change telescope magnification?

No. The adapter contains no optical elements and does not independently alter focal length or magnification.

Can it be used with ZWO or QHYCCD cameras?

It can be incorporated into a suitable camera assembly when the mating interfaces match M54x0.75 female and M36x1.0 male. Compatibility should be verified for the exact camera and adapter configuration.

Is the adapter adjustable?

No. It is a fixed-length mechanical thread conversion adapter.

Does this product require any software or power supply?

No. It is a passive mechanical component.
