Specification guide

Optical filter specifications for RFQ preparation

Use this checklist to turn wavelength needs, blocking targets and mechanical constraints into a reviewable optical filter request.

Wavelength window

Record the target pass band, blocked range, center wavelength and tolerance. A longpass or shortpass request should not rely on the cutoff name alone.

Signal control

Capture transmission target, OD or blocking depth, expected background light and any adjacent channel that could create leakage.

Build context

Add AOI, substrate preference, size, thickness, quantity, drawing constraints and any spectrum or reference curve available.

Product visuals

Real component photos are used as replaceable current references.

The component PDF has been ingested into the project records. Public content uses Lumalyx planning aliases for RFQ language, while component page and model references stay in the project records for traceability.

Naming pattern: LMX-{DOMAIN}-{APPLICATION}-{COMPONENT}-{ANCHOR}-{VARIANT}. Example: LMX-MED-PCR-CH-FAM-A maps to a component FAM qPCR channel example without making the component model a Lumalyx SKU.

RFQ fields to prepare before review

A stronger request separates optical behavior from mechanical and commercial context. The same wavelength label can still require different blocking depth, pass-band width, angle behavior or size limits.

  • Target pass band or center wavelength
  • Blocked range and required OD or cutoff depth
  • Transmission target for the useful signal
  • FWHM or bandwidth when the part is narrowband or bandpass
  • AOI, substrate, coating side, size and thickness
  • Instrument, detector, light source and quantity context

Catalog example fields

The reviewed component catalog set covers longpass, shortpass, narrowband and neutral density vocabulary. These examples show the type of fields to prepare, not final Lumalyx product commitments.

Lumalyx planning aliases

Component catalog entries are translated into Lumalyx planning aliases before public use. Examples from the medical catalog include LMX-MED-PCR-CH-FAM-A for a qPCR FAM channel example, LMX-MED-FLOW-BP-480-A for a flow cytometry bandpass example, and LMX-MIR-SPIRO-BP-4P65UM-A for a mid-IR spirometer reference.

What Lumalyx reviews from your request

Lumalyx can structure the inquiry around the useful signal, unwanted signal, geometry and documentation needed for engineering review. Final values should be confirmed against spectra, drawings and current catalog or custom-build options.

  • Whether the request is longpass, shortpass, narrowband, bandpass or neutral density work
  • Whether the wavelength and blocking fields are complete enough for comparison
  • Whether spectra, drawings or sample constraints are needed before quoting

Prepare a reviewable RFQ

Send the known wavelength, blocking, geometry and quantity fields. Mark unknown values clearly so engineering review can focus on the missing decisions.

FAQ

Common RFQ questions.

These answers keep the request focused on reviewable engineering fields.

Which optical filter specs should I prepare first?

Start with pass band or center wavelength, blocked range, transmission target, OD or cutoff depth, AOI, substrate, size and quantity.

Can I submit an RFQ if some values are unknown?

Yes. Mark unknown fields clearly and include the application, light source, detector and any spectra so the review can identify what is missing.

Are catalog example values final Lumalyx specifications?

No. They are examples of specification fields. Current values, availability and suitability require RFQ review.
