How ordering works
Simple, documented and trackable — from quotation to delivery.
Request a quote
Use the quote form or email sales@dichroptics.com with the part (our SKU or the brand part number you use now), quantity and destination country. We reply with a written quotation, usually within one business day.
Proforma invoice
Once you confirm, we issue a proforma invoice listing items, unit prices, shipping, delivery terms and bank details — suitable for most purchasing departments.
Payment by bank transfer via Wise
Pay by international bank transfer in USD or EUR to our Wise account. Bank details are provided on the proforma invoice only.
Dispatch & tracking
In-stock items typically ship within 3–7 business days after payment, by tracked international express. You receive the tracking number and a commercial invoice. Custom parts have longer lead times, stated on the quotation.
Delivery with spectral data
Each shipment includes the spectral / test data for the supplied batch.
Shipping
- Free shipping on orders of 5+ units or US$600+.
- Otherwise a flat US$75 shipping & handling per order.
- Tracked international express; transit time depends on destination and is typically several business days after dispatch.
- Delivery terms: DAP (Delivered At Place). The buyer is responsible for import duties, VAT/GST and any customs brokerage charges in the destination country.
Prices & quotations
- All prices in USD per unit (per set for filter sets), excluding import duties and taxes.
- “From” prices apply at 5+ units of the same item; single-unit prices are listed alongside.
- Custom wavelengths, bandwidths and sizes are quoted on request.
- Quotations are valid for 30 days unless stated otherwise.
Quality, returns & out-of-spec parts
Every filter is supplied against its stated specification, with spectral data for the batch. If a filter does not meet its stated specification, or arrives damaged, contact us within 30 days of delivery with your order number, a description and (where possible) your measurement or photos. After review we will replace the filter or refund it, and cover return shipping for confirmed out-of-spec or transit-damaged items.
Standard catalog items that are in specification and unused may be returned by agreement; the buyer covers return shipping. Custom-made parts are non-returnable unless out of specification.
Export compliance
Optical components can be subject to export regulations. We may ask for end-user and end-use information for some destinations or quantities, and we may decline orders we cannot ship lawfully.
