Custom work is not a slogan in this catalogue; it is visible in the listings themselves. A customised optical band pass filter offered at the buyer's choice of 340, 505, 630 and 800 nm. A customised sapphire stepped optical window, machined to a mounting profile. A customised dielectric coating reflector mirror at 25.4 × 3 mm in JGS1 glass. A customised 300 mm K9 glass concave reflecting mirror. Each of those is a documented storefront listing, and together they describe a manufacturer whose default mode for non-standard parts is 'send the specification' — backed by a registered OEM/ODM service offer and sample availability before volume.
What Customisation Covers
- Dimensions — non-standard diameters, thicknesses, stepped and shaped profiles, large formats up to the documented 300 mm class.
- Wavelengths — filter centre wavelengths, cut edges and coating designs set to the instrument's band plan.
- Materials — the documented material set: optical glass (K9/BK7 class), JGS1, ZnSe, ZnS, CaF2, MgF2, sapphire, quartz and silicon. That set is the union of the materials recorded across the whole catalogue — windows, lenses, mirrors and other families each carry their own records — so it does not mean every material is available for every product family; the material for a specific part is confirmed against that part's family record.
- Patterns — submit a reticle pattern drawing or description for evaluation; no custom reticle listing or minimum is recorded, so availability and specification are confirmed in the quotation.
- Assemblies — components can be specified together against one drawing package, with each component's supply confirmed item by item in the enquiry.
How a Custom Enquiry Works
Send the drawing, or the specification in whatever form it exists — a sketch with dimensions and tolerances is a legitimate starting point. Mark which items you take to be catalogue and which custom; each item's supply, and the minimum quantity for any custom content, is confirmed item by item in the quotation. Samples are part of the documented offer, so a custom part can be evaluated before the volume commitment. Buyers who have not yet fixed their specification can start from the nearest catalogue family — lenses, filters, windows, prisms — and mark the deviations.
Frequently Asked Questions
Is OEM/ODM service documented?
Yes — OEM/ODM service and sample availability are part of the manufacturer's registered service offer, and the own-brand line is sold under its JS brand.
What is the minimum for a custom part?
It is confirmed independently for your part and stated in the quotation. A documented catalogue item's minimum — 10 pieces on many lines, 1 piece on the documented microscope wire reticle and selected filters — applies to that item only; it does not set the minimum for a neighbouring custom part, even one in the same family.
What should I send first?
The drawing or dimensioned sketch, material, coating or wavelength requirements, and the quantity. A first quotation is written against those inputs, and any further field is confirmed in the enquiry.
From Sketch to Quotation: What Happens to a Custom Drawing
A custom drawing is the starting document for a custom enquiry, and the first version is worth sending complete. A drawing can hold catalogue content and genuinely custom content side by side; mark which items you take to be catalogue and which custom, and each item's supply, and the minimum quantity for any custom content, is confirmed item by item in the quotation. For the custom content, the drawing itself states the fields that matter: radii, thicknesses, edge treatments and the material asked for, read against the documented material set. Tolerances are then read as part of the specification itself — a drawing that marks which dimensions are functional and which are reference states the buyer's priorities plainly, rather than leaving every figure uniformly tight. State the quantity you need for the custom content in the enquiry; a catalogue item's documented minimum belongs to that item and is not carried across to the custom part beside it. One habit helps: send the drawing with a short note naming the instrument the part serves.
