Raytools BM06K D37×F100 Focus Lens Assembly: Compatibility and Replacement Guide
The Raytools BM06K D37×F100 Focus Lens Assembly is a replacement optic assembly identified by the BM06K head designation and the D37×F100 size notation. The designation indicates a nominal 37 mm diameter and 100 mm focal length, but those dimensions alone do not prove compatibility with every BM06K configuration. Before ordering, compare the existing assembly, machine and laser setup, and supplier documentation; confirm the optical specification and mechanical interface as well as the model name.
This guide explains how to check fit, select a replacement, and prepare a clear supplier inquiry. It is intended for machine operators, maintenance teams, and purchasing professionals sourcing a replacement or spare. QIRUI LASER can review the information you provide and help assess whether the requested assembly matches your application; final compatibility should be confirmed against the relevant equipment specifications.
Key Takeaways
- D37×F100 identifies nominal dimensions of 37 mm diameter and 100 mm focal length; verify these against the actual part and technical documentation.
- Compatibility also depends on the head configuration, mounting details, optical material and coating, wavelength, and operating conditions.
- Share clear photos, part markings, machine information, and operating requirements before placing an order.
- Ask suppliers to confirm the exact scope of supply, available documentation, packaging, MOQ, and lead time in writing.
Who This Guide Is For
This guide is for buyers replacing a damaged, worn, or unavailable focus lens assembly associated with a Raytools BM06K laser head. It is also useful for distributors and service providers who need to check a part before quoting or holding inventory. If you are choosing an assembly for a different head model, do not assume that a similar diameter or focal length makes it interchangeable.
What the D37×F100 Designation Tells You
Nominal dimensions and function
In this product designation, D37 refers to a nominal diameter of 37 mm, while F100 refers to a nominal focal length of 100 mm. A focus lens assembly directs and focuses the laser beam in the cutting head, so its optical and mechanical characteristics both matter. The designation is a useful starting point for identification, not a complete technical drawing or a substitute for checking the assembly interface.
Information that the designation does not establish
The name by itself does not confirm the lens material, coating, wavelength range, allowable laser power, thickness, edge details, or exact mounting arrangement. These details may vary by configuration or supplier and should be checked against reliable documentation for the specific part. For example, a 1,000 W laser source is an application detail to report to a supplier, not a confirmed power rating for this lens assembly.
Compatibility Checks Before Replacement
1. Identify the head and existing part
Record the laser head model and any version, serial, or configuration information available from the equipment label or service records. Photograph the existing assembly from several angles, including visible markings and the way it sits in the head. If the old component is damaged, avoid relying on a single measurement taken from a deformed or contaminated part.
2. Confirm dimensions and mounting
Check whether the 37 mm nominal diameter and 100 mm focal length match the original part or the equipment documentation. Also verify the assembly’s external dimensions, seating surfaces, retention method, and orientation where applicable. If you do not have a drawing or a reliable measurement method, send photographs and part details to the supplier rather than guessing from appearance.
3. Match the optical requirements
Confirm the laser wavelength, source type, and operating power requirements for your machine. The wavelength should be specified in nanometres (nm), and the power rating should be stated in watts (W); ask the supplier to confirm suitability for your actual operating conditions. Do not treat a lens with matching physical dimensions as suitable if its optical specification is unverified.
4. Check the complete application
Consider the cutting head configuration, process, operating environment, and maintenance history. A part that fits mechanically may still be unsuitable if its optical properties or coating do not match the laser setup. When the machine has been modified or its maintenance records are incomplete, obtain confirmation from the equipment provider or a qualified service contact before installation.
Selection Framework for Buyers
| Check | What to confirm | Why it matters |
|---|---|---|
| Model and configuration | BM06K head identification and any version details | A model name alone may not identify every configuration. |
| Dimensions | 37 mm nominal diameter, 100 mm nominal focal length, and mounting details | Physical and optical fit both affect replacement suitability. |
| Optical specification | Material, coating, wavelength, and applicable operating conditions | These characteristics must suit the laser source and process. |
| Order scope | Assembly contents, documentation, packaging, MOQ, and lead time | Clear terms help prevent purchasing and maintenance delays. |
Materials, Coatings, and Assembly Details
Focus optics are supplied in different material and coating configurations depending on their intended wavelength and operating requirements. Do not select a material or coating based only on a general description such as “laser lens”; request the specification for the exact assembly being quoted. If the original part carries a marking or part number, include it with your inquiry so the supplier can use it as a reference.
Goto QIRUI LASER to know more.
Clarify whether the quoted item is the complete focus lens assembly or only an optical element. Ask what components are included, whether the assembly is supplied ready for the specified interface, and what handling or installation instructions are available. These questions are especially important when comparing quotations that may describe different supply scopes.
Pricing, MOQ, and Lead Time
Price and availability depend on the confirmed specification, order quantity, stock status, and whether the request requires a standard or specially specified configuration. MOQ and lead time can therefore vary, and they should be confirmed for the exact item rather than inferred from the product name. For a time-sensitive replacement, ask the supplier to state the estimated dispatch timing and shipping terms in the quotation.
When comparing offers, evaluate more than the unit price. Check that each supplier has quoted the same model, dimensions, optical requirements, assembly scope, and documentation. A lower-priced item is not a like-for-like alternative if a key specification remains unclear.
Supplier Evaluation Checklist
- Can the supplier explain how the offered assembly corresponds to the BM06K D37×F100 request?
- Will the supplier confirm dimensions, optical specifications, and mounting details in writing?
- Can they identify exactly what is included in the assembly and provide relevant product documentation if available?
- Are MOQ, lead time, packaging, shipping terms, and quotation validity clearly stated?
- Is there a practical channel for resolving specification questions before purchase?
Ask for evidence appropriate to the product and order, such as a dimension drawing or specification sheet, when available. Do not rely on broad claims about compatibility or performance without confirming the exact configuration and intended use. Keep the supplier’s written confirmation with your purchasing and maintenance records.
Common Replacement Mistakes to Avoid
One common mistake is ordering by model name alone without confirming dimensions and configuration. Another is assuming that a matching diameter guarantees the correct focal length, coating, or wavelength suitability. Buyers can also overlook whether the quotation covers a complete assembly or a lens element only.
Avoid installing a part when its identity or optical suitability is uncertain. Keep optics protected from dust and handling contamination, and follow the equipment manufacturer’s service procedure for removal and installation. If the replacement does not seat correctly or the machine’s process changes unexpectedly, stop and have the assembly and installation checked by a qualified technician.
How to Request a Quote from QIRUI LASER

Include photos of the existing assembly and any markings, plus the laser wavelength in nm and rated operating power in W if available. You can also specify your destination, preferred delivery timing, and whether you need a standard replacement or a technical review before ordering.
QIRUI LASER can use these details to review the requested specification, clarify open questions, and provide a quotation subject to confirmation of availability and configuration. If you are unsure which information is relevant, send the machine label and existing-part photos first. This gives our team a clearer basis for discussing fit and sourcing options without assuming compatibility.
Conclusion
The Raytools BM06K D37×F100 designation points to a 37 mm nominal diameter and 100 mm nominal focal length, but it is not enough on its own to establish a safe, correct replacement. Confirm the head configuration, mounting interface, optical specification, wavelength, and operating conditions before purchasing. The most practical next step is to gather the part markings, photos, machine details, and order quantity, then request written confirmation from a qualified supplier.
